- * Enhanced `FFmpegFrameRecorder` to support conversion between audio sample formats (for the experimental AAC encoder among other things) and to let two different threads call `record(samples)` and `record(image)` simultaneously, plus a couple of other features like `setFrameNumber()`, which lets users skip image frames (achieving variable frame rate) - * Added a `javacpp.skip` property to `pom.xml`, such that a command like `mvn package -Pall -Djavacpp.skip=true` only recompiles the Java source files, but also added `platform.root` and `compiler.path` properties, which map directly to JavaCPP's for convenience - -### July 21, 2012 version 0.2 - * Provided new `javacv-linux-arm.jar` build thanks to Jeremy Nicola (issue #184) - * Additional default properties inside `pom.xml` make it

maybe Linux (issue #212) - -### May 27, 2012 version 0.1 - * Started using version numbers, friendly to tools like Maven, and placing packages in a sort of [Maven repository](http://maven2.javacv.googlecode.com/git/) - * JavaCV can now extract and load native dependent libraries such as `libopencv_core.so.2.4`, `libopencv_core.2.4.dylib`, `opencv_core240.dll`, etc. from Java resources placed inside the `com.googlecode.javacv.cpp.<platform.name>` package (i.e.: under the `/com/googlecode/javacv/cpp/<platform.name>/` directory of a JAR file in the classpath) (issue #146) - * Included new `FaceApplet` sample to demonstrate [How to use JavaCV in an applet](http://code.google.com/p/javacv/wiki/HowToMakeAnApplet) - * Added handy `IplImage.asCvMat()` and

directory layout - * Made it easier to create one massive statically linked native library by passing something like "-Xcompiler -Wl,-static -o javacv" as command line options to JavaCPP, usually from inside `build.xml` or `pom.xml` (issue #146) - * Fixed missing parameter from `CvANN_MLP.create()` - * Added methods `cvCalcCovarMatrixEx()`, `cvEigenDecomposite()`, and `cvEigenProjection()` taking an `IplImage[]` as argument for convenience - * `VideoInputFrameGrabber.start()` now accepts a `connection` argument such as `VI_COMPOSITE` to support analog cameras and what not - * Fixed

`CvDrawShape`, `CvVectors`, `CvParamGrid`, `Cv*Params`, `CvSVM*`, `CvPair16u32s`, `CvDTree*` `CvTrainTestSplit`, `CvMLData`, `FeatureEvaluator`, and `*DataMatrixCode` - * Increased versatility of `IplImage.createFrom()`, `copyFrom()`, `copyTo()`, `getBufferedImage()` by providing a `flipChannels` parameter, whose effect was previously mistakenly forced onto four-channel images of byte values only (issue #163) - * Fixed a couple of things with `CvMat.get()/put()` (issue #167) - * In addition to an `IplImage`, we may now specify the pixel format of the data when calling `FFmpegFrameRecorder.record()`, but otherwise when `IplImage.nChannels == 2`, it assumes `PIX_FMT_NV21`, allowing for easy and efficient encoding of data captured from the camera on Android (issue #160), image objects we can also convert to RGB using `cvCvtColor()` with `CV_YUV420sp2BGR` - * Fixed seeking capabilities of `FFmpegFrameGrabber` (issue #162) and added `getLengthInFrames()` and `getLengthInTime()` methods to query the duration of streams, when known - * Enhanced `IplImage.clone()` and `create*Compatible()` with cloning of their `BufferedImage` to make it easier to keep color components in the right order (issue #163) - * Refactored `FrameGrabber` and `FrameRecorder` a bit to accommodate new `createDefault(...)` and `create(String className, ...)` factory methods, offering to users an easier selection method to work around limitations of some APIs (issue #70) - * Adjusted `GNImageAligner`, `ProCamTransformer`, etc. to support alignment of only the projector display on textureless surface planes - * Renamed a few more `Settings` properties to reflect better their meanings - -### February 18, 2012 - * Added `GLCanvasFrame` to show OpenGL renderbuffers on screen, plus a new factory method `JavaCVCL.createCLGLImageFrom()` to create compatible ones from `IplImage` objects, as well as more user-friendly `getGLContext()`, `getGL()` and `getGL2()` methods - * Fixed various things of the original `CanvasFrame`, and `JavaCV.createCLImage()` and `createIplImage()`, also appending `From` to their names - * New `createPinnedBuffer()` and `createPinnedIplImage()` factory methods in `JavaCVCL` to allocate page-locked memory for faster CPU<->GPU transfers, but it does not seem to work for OpenCL image objects, only linear buffer objects :( - * Fixed and enhanced `GNImageAlignerCL` and `ProjectorDevice` (its `useOpenGL` property) to support fully OpenCL and OpenGL acceleration - * Refactored `Parallel` a bit so that we may set the number of threads it uses via its static `numThreads` property or the "com.googlecode.javacv.numthreads" system property, which defaults to `Parallel.getNumCores() = Runtime.getRuntime().availableProcessors()` - * Cleaned up and renamed some methods in `JavaCV`, while adding `boundingRect()`, functionally similar to `cvBoundingRect`, but better adapted to compute a properly aligned and padded ROI - * Inserted a couple of missing `allocate()` inside `opencv_flann` - * Updated `ObjectFinder` with a `Settings.useFLANN` property to let it use FLANN via OpenCV - * Cleaned up and optimized `HandMouse` - * `CanvasFrame`, `FrameGrabber`, `FrameRecorder`, and `ProjectiveDevice` objects now throw `Exception` objects of a nested class instead of the too generic `java.lang.Exception` one - * Moved parallel execution of

properties here and there to correct typos and reflect better their meanings - * Updated `freenect` to reflect the latest changes of OpenKinect's master branch - * FFmpeg and other libraries did not work under Android when compiled with the latest NDK, r7 (issue #147): Fixed in JavaCPP - * Moved `IplImage.timestamp` to `FrameGrabber`, also adding a `frameNumber` property, both allowing to seek within streams too - * Removed `triggerFlushSize` property from `CameraDevice` and `FrameGrabber`, instead relying on the `numBuffers` property to decide the required size of a buffer flush - * Corrected the logic behind `FFmpegFrameGrabber.getFrameRate()` and `getTimestamp()` (issue #151) - * Created a `BufferRing` class for convenient circular rings of large buffers that require manual release of resources, such as OpenCL memory - * Added a few more useful methods to `FrameGrabber`, including `restart()`, `flush()`, and `delayedGrab()` (to be used in conjunction with `getDelayedTime()` and `getDelayedImage()`) - * Inserted `cvLoadImageBGRA()` and `cvLoadImageRGBA()` methods into `opencv_highgui` to load color images compatible with OpenCL more easily - * `JavaCvErrorCallback` now outputs messages to `Logger` instead of `System.err` - * Defined `VI_COM_MULTI_THREADED` for `videoInput`, allowing it to run on multiple threads if needed - -### January 8, 2012 - * JavaCV should now have an easier time automatically finding libraries inside standard directories such as `/usr/local/lib/`, `/opt/local/lib/`, and `C:\opencv\`, even when they are not part of the system configuration or PATH (issue #127) - * Renamed `set()` and `fill()` methods to `put()` inside `CvPoint*` classes, for better naming consistency - * Renamed `FrameGrabber.ColorMode` to `ImageMode` and its `BGR` value to `COLOR` to reflect the fact that a `FrameGrabber` instance can return color images in some arbitrary format, but added a new `pixelFormat` property to let users know or specify the exact pixel format desired, such as `PIX_FMT_BGR24`, etc. in the case of `FFmpegFrameGrabber` - * After `FFmpegFrameGrabber.start()`, the `format`, `imageWidth`, `imageHeight`, and `frameRate` properties switch to their effective values - * Added new `FrameGrabber.sensorPattern` property to obtain the Bayer filter layout of raw data from `DC1394FrameGrabber` and `FlyCaptureFrameGrabber` - * Readded to `KDTree`, `Index`, and `HOGDescriptor` some functions with `FloatPointer` and `IntPointer` arguments that were mistakenly removed when OpenCV switched to using `cv::InputArray` and `cv::OutputArray` parameter types (issue #134) - * Renamed `ProjectiveGainBiasTransformer` to `ProjectiveColorTransformer` - * Added a few classes to do some processing using OpenCL and OpenGL: `JavaCVCL`, `GNImageAlignerCL`, `ProjectiveTransformerCL`, `ProjectiveColorTransformerCL`, and `ProCamTransformerCL` with some other related files - * Renamed `Parallel.numCores` to the more conventional `Parallel.NUM_CORES` - * Added new `FaceRecognition.java` sample from Stephen L. Reed - * Inserted a couple of missing calls to `Loader.load()` (issue #142) - * Improved hacks for `Loader.load()` in JavaCPP make JavaCV work on Android 4.0 - * New `PS3EyeFrameGrabber` from Jiri Masa can now grab images using the SDK from Code Laboratories -

-### August 20, 2011 - * Upgraded support to OpenCV 2.3.1 - * An output argument of type `cv::Mat` or `cv::OutputArray` returned with a size 0 now correctly sets `CvArr.address = 0` - * Fixed `IplImage.createFrom()` and `copyFrom()` when called on objects returned by `BufferedImage.getSubimage()` - * Added missing allocator to `CvRNG` - * `OpenCVFrameGrabber` now detects when CV_CAP_PROP_POS_MSEC is broken and gives up calling `cvGetCaptureProperty()` - * New `OpenKinectFrameGrabber.grabDepth()` and `grabVideo()` methods to capture "depth" and "video" simultaneously, regardless of the mode -

* Changed `Marker.getCenter()` back to the centroid, because it has better noise averaging properties and gives in practice more accurate results than the actual center - * Added hack to `OpenCVFrameGrabber.start()` to wait for `cvRetrieveFrame()` to return something else than `null` under Mac OS X - * FFmpeg now works properly on Windows and Android (issue #63) with newer binaries - * New `videoInputLib` wrapper and corresponding `VideoInputFrameGrabber` to capture using DirectShow, useful under Windows 7 where OpenCV and FFmpeg can fail to capture using Video for Windows (issue #58) - * `GeometricCalibrator` now reports the maximum errors in addition to the average (RMS) errors - -### April 7, 2011 - * Added a `format` property to `CameraDevice`, `FrameGrabber`, and `FrameRecorder`, mostly useful for `FFmpegFrameGrabber`, where interesting values include "dv1394", "mjpeg", "video4linux2", "vfwcap", and "x11grab" - * `OpenCVFrameRecorder` now uses `CV_FOURCC_PROMPT` under Windows as default since `CV_FOURCC_DEFAULT` crashes (issue #49) - * Added hack to make sure the temporarily extracted library files get properly deleted under Windows - * JavaCPP now loads classes more lazily - * Fixed most occurences of `UnsatisfiedLinkError` (issue #54), but some corner cases may require a call to `Loader.load()` on the class one wishes to use - * Added (rudimentary) outlier detection and modified zero threshold handling in the image alignment framework - * New `JavaCV.hysteresisThreshold()` feature - * New `HandMouse` functionality, which depends on the image alignment framework - * Fixed `ProjectiveDevice.distort()`, which mistakenly undistorted images instead - * New `HoughLines` sample thanks to Jeremy Nicola - -### February 19, 2011 - * Switched from JNA to JavaCPP, which has a lower overhead and supports C++, bringing hope that future versions of JavaCV will support features of OpenCV available only through the C++ API - * Consequently, the syntax of various operations have changed a bit, but the transition should not be too painful - * As a happier consequence, this also fixes the problem with SSE instructions on 32-bit x86 (issue #36) - * Also, JavaCPP does not have any limitations or performance issues with large data structures (issue #10 and issue #14) - * Added support for OpenCV 2.2 (issue #42), but dropped support for all previous versions - * Added samples provided by users (issue #1, issue #45, and issue #46) - * Added deinterlace setting to `FFmpegFrameGrabber` having it call `avpicture_deinterlace()` (issue #38) - * Enhanced a few things of the image alignment algorithm - * Tried to fix image format conversion inside `FlyCaptureFrameGrabber`, but this is going to require more careful debugging - * Fixed and added various other things I forget - -### December 2, 2010 -

* Made clearer the error messages thrown from `FrameGrabber` objects, when `start()` may not have been called - * Fixed version specific declarations of `CvStereoBMState` and related functions - * Fixed conditions that could crash `cvkernels` - -### November 4, 2010 - * Renamed the package namespace to `com.googlecode.javacv`, which makes more sense now that JavaCV has been well anchored at Google Code for more than a year, piggybacking on the unique and easy-to-remember domain name - * Included new FFmpeg wrapper classes `avutil`, `avcodec`, `avformat`, `avdevice`, `avfilter`, `postprocess`, and `swscale`, eliminating the need of the separate FFmpeg-Java package - * `CanvasFrame` now redraws its `Canvas` after the user resizes the `Frame` - * Fixed the `Error` thrown when calling `CanvasFrame.showImage()` from the EDT - * Added check to `DC1394FrameGrabber` so that a "Failed to initialize libdc1394" does not crash the JVM - * `FFmpegFrameGrabber` does not crash anymore when forgetting to call `start()` before a `grab()` or `trigger()` - * `FrameGrabber` now selects the default grabber a bit better - * Made sweeping changes (for the better, but still not finalized) to `GNImageAligner`, `ProjectiveTransformer`, `ProjectiveGainBiasTransformer`, and `ProCamTransformer`... - * Added to `JavaCV` more methods related to transformation of planes: `perspectiveTransform()`, `getPlaneParameters()`, `getPerspectiveTransform()`, and `HtoRt()`, as well as `ProjectiveDevice.getFrontoParallelH()` - * Added a static `autoSynch` flag to all `Structure` classes of `cxcore`, `cv`, and `cvaux`, which you may set to `false` prior to the return of things like big and heavy `CvSeq` to make them load faster and to avoid stack overflows, but accessing fields will then require manual calls to `readField()` and `writeField()` (issue #10 and #14) - * Added missing `ByValue` subclasses to `CvSeq`, `CvSet`, `CvContourTree`, and `CvChain`... Any others missing? - * Fixed `Exception` thrown from `cvCreateHist()` under JNA 3.2.7 (issue #26) - * Enhanced `CvMat.put()`, which now supports setting submatrices - * Improved inside `IplImage` the support of `BufferedImage`, especially those using a `DirectColorModel` (issue #23) - * Fixed crash in `cvkernels` when color transformation `X` is `null` - -### July 30, 2010 - * Fixed crash that would occur in `CanvasFrame` for some video drivers - * `FFmpegFrameGrabber` now supports other input formats (devices), such as `x11grab` that can be used for screencasting - * Added `JavaCV.median()` function, and `JavaCV.fractalTriangleWave()` now respects image ROI - * Fixed background subtraction in `cvaux` - * Fixed crash inside the code for direct alignment caused by the ROI getting set outside the image plane - * Added `deltaScale` and `tryToFixPlane` to `GNImageAligner.Settings` (the first used in `ImageTransformer.Parameters` as increment, randomly selected forward or backward, for finite difference), which sometimes help to jump over local minima - -### May 30, 2010 - * Removed redundant `CvMemStorage.clearMem()` method, use `cvClearMemStorage()` - * Fixed the sample `Test2` class that did not work under Windows - * Fixed corruption by the `cvkernels` `transformer` at the borders - * Modified `CanvasFrame` constructors and added a `gamma` argument used by `showImage(IplImage)` - * `CanvasFrame` now lets users resize the frame, while displayed images are stretched to fit the new size -

By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Lesser General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3.

* Added a `javacpp.skip` property to `pom.xml`, such that a command like `mvn package -Pall -Djavacpp.skip=true` only recompiles the Java source files, but also added `platform.root` and `compiler.path` properties, which map directly to JavaCPP's for convenience - -### July 21, 2012 version 0.2 - * Provided new `javacv-linux-arm.jar` build thanks to Jeremy Nicola (issue #184) - * Additional default properties inside `pom.xml` make it easier to build JavaCV from source (issue #202), calling `mvn package` now succeeds with only OpenCV and a C++ compiler for JavaCPP -

* Increased versatility of `IplImage.createFrom()`, `copyFrom()`, `copyTo()`, `getBufferedImage()` by providing a `flipChannels` parameter, whose effect was previously mistakenly forced onto four-channel images of byte values only (issue #163) - * Fixed a couple of things with `CvMat.get()/put()` (issue #167) - * In addition to an `IplImage`, we may now specify the pixel format of the data when calling `FFmpegFrameRecorder.record()`, but otherwise when `IplImage.nChannels == 2`, it assumes `PIX_FMT_NV21`, allowing for easy and efficient encoding of data captured from the camera on Android (issue #160), image objects we can also convert to RGB using `cvCvtColor()` with `CV_YUV420sp2BGR` - * Fixed seeking capabilities of `FFmpegFrameGrabber` (issue #162) and added `getLengthInFrames()` and `getLengthInTime()` methods to query the duration of streams, when known - * Enhanced `IplImage.clone()` and `create*Compatible()` with cloning of their `BufferedImage` to make it easier to keep color components in the right order (issue #163) -

* Adjusted `GNImageAligner`, `ProCamTransformer`, etc. to support alignment of only the projector display on textureless surface planes - * Renamed a few more `Settings` properties to reflect better their meanings - -### February 18, 2012 - * Added `GLCanvasFrame` to show OpenGL renderbuffers on screen, plus a new factory method `JavaCVCL.createCLGLImageFrom()` to create compatible ones from `IplImage` objects, as well as more user-friendly `getGLContext()`, `getGL()` and `getGL2()` methods - * Fixed various things of the original `CanvasFrame`, and `JavaCV.createCLImage()` and `createIplImage()`, also appending `From` to their names - * New `createPinnedBuffer()` and `createPinnedIplImage()` factory methods in `JavaCVCL` to allocate page-locked memory for faster CPU<->GPU transfers, but it does not seem to work for OpenCL image objects, only linear buffer objects :( - * Fixed and enhanced `GNImageAlignerCL` and `ProjectorDevice` (its `useOpenGL` property) to support fully OpenCL and OpenGL acceleration - * Refactored `Parallel` a bit so that we may set the number of threads it uses via its static `numThreads` property or the "com.googlecode.javacv.numthreads" system property, which defaults to `Parallel.getNumCores() = Runtime.getRuntime().availableProcessors()` - * Cleaned up and renamed some methods in `JavaCV`, while adding `boundingRect()`, functionally similar to `cvBoundingRect`, but better adapted to compute a properly aligned and padded ROI - * Inserted a couple of missing `allocate()` inside `opencv_flann` - * Updated `ObjectFinder` with a `Settings.useFLANN` property to let it use FLANN via OpenCV - * Cleaned up and optimized `HandMouse` - * `CanvasFrame`, `FrameGrabber`, `FrameRecorder`, and `ProjectiveDevice` objects now throw `Exception` objects of a nested class instead of the too generic `java.lang.Exception` one -

* Moved `IplImage.timestamp` to `FrameGrabber`, also adding a `frameNumber` property, both allowing to seek within streams too - * Removed `triggerFlushSize` property from `CameraDevice` and `FrameGrabber`, instead relying on the `numBuffers` property to decide the required size of a buffer flush - * Corrected the logic behind `FFmpegFrameGrabber.getFrameRate()` and `getTimestamp()` (issue #151) - * Created a `BufferRing` class for convenient circular rings of large buffers that require manual release of resources, such as OpenCL memory - * Added a few more useful methods to `FrameGrabber`, including `restart()`, `flush()`, and `delayedGrab()` (to be used in conjunction with `getDelayedTime()` and `getDelayedImage()`) - * Inserted `cvLoadImageBGRA()` and `cvLoadImageRGBA()` methods into `opencv_highgui` to load color images compatible with OpenCL more easily - * `JavaCvErrorCallback` now outputs messages to `Logger` instead of `System.err` - * Defined `VI_COM_MULTI_THREADED` for `videoInput`, allowing it to run on multiple threads if needed - -### January 8, 2012 - * JavaCV should now have an easier time automatically finding libraries inside standard directories such as `/usr/local/lib/`, `/opt/local/lib/`, and `C:\opencv\`, even when they are not part of the system configuration or PATH (issue #127) - * Renamed `set()` and `fill()` methods to `put()` inside `CvPoint*` classes, for better naming consistency - * Renamed `FrameGrabber.ColorMode` to `ImageMode` and its `BGR` value to `COLOR` to reflect the fact that a `FrameGrabber` instance can return color images in some arbitrary format, but added a new `pixelFormat` property to let users know or specify the exact pixel format desired, such as `PIX_FMT_BGR24`, etc. in the case of `FFmpegFrameGrabber` - * After `FFmpegFrameGrabber.start()`, the `format`, `imageWidth`, `imageHeight`, and `frameRate` properties switch to their effective values - * Added new `FrameGrabber.sensorPattern` property to obtain the Bayer filter layout of raw data from `DC1394FrameGrabber` and `FlyCaptureFrameGrabber` - * Readded to `KDTree`, `Index`, and `HOGDescriptor` some functions with `FloatPointer` and `IntPointer` arguments that were mistakenly removed when OpenCV switched to using `cv::InputArray` and `cv::OutputArray` parameter types (issue #134) - * Renamed `ProjectiveGainBiasTransformer` to `ProjectiveColorTransformer` - * Added a few classes to do some processing using OpenCL and OpenGL: `JavaCVCL`, `GNImageAlignerCL`, `ProjectiveTransformerCL`, `ProjectiveColorTransformerCL`, and `ProCamTransformerCL` with some other related files - * Renamed `Parallel.numCores` to the more conventional `Parallel.NUM_CORES` - * Added new `FaceRecognition.java` sample from Stephen L.

* New `JavaCV.hysteresisThreshold()` feature - * New `HandMouse` functionality, which depends on the image alignment framework - * Fixed `ProjectiveDevice.distort()`, which mistakenly undistorted images instead - * New `HoughLines` sample thanks to Jeremy Nicola - -### February 19, 2011 - * Switched from JNA to JavaCPP, which has a lower overhead and supports C++, bringing hope that future versions of JavaCV will support features of OpenCV available only through the C++ API - * Consequently, the syntax of various operations have changed a bit, but the transition should not be too painful - * As a happier consequence, this also fixes the problem with SSE instructions on 32-bit x86 (issue #36) - * Also, JavaCPP does not have any limitations or performance issues with large data structures (issue #10 and issue #14) - * Added support for OpenCV 2.2 (issue #42), but dropped support for all previous versions -

* Made clearer the error messages thrown from `FrameGrabber` objects, when `start()` may not have been called - * Fixed version specific declarations of `CvStereoBMState` and related functions - * Fixed conditions that could crash `cvkernels` - -### November 4, 2010 - * Renamed the package namespace to `com.googlecode.javacv`, which makes more sense now that JavaCV has been well anchored at Google Code for more than a year, piggybacking on the unique and easy-to-remember domain name - * Included new FFmpeg wrapper classes `avutil`, `avcodec`, `avformat`, `avdevice`, `avfilter`, `postprocess`, and `swscale`, eliminating the need of the separate FFmpeg-Java package - * `CanvasFrame` now redraws its `Canvas` after the user resizes the `Frame` - * Fixed the `Error` thrown when calling `CanvasFrame.showImage()` from the EDT - * Added check to `DC1394FrameGrabber` so that a "Failed to initialize libdc1394" does not crash the JVM - * `FFmpegFrameGrabber` does not crash anymore when forgetting to call `start()` before a `grab()` or `trigger()` - * `FrameGrabber` now selects the default grabber a bit better - * Made sweeping changes (for the better, but still not finalized) to `GNImageAligner`, `ProjectiveTransformer`, `ProjectiveGainBiasTransformer`, and `ProCamTransformer`... -

* Added a static `autoSynch` flag to all `Structure` classes of `cxcore`, `cv`, and `cvaux`, which you may set to `false` prior to the return of things like big and heavy `CvSeq` to make them load faster and to avoid stack overflows, but accessing fields will then require manual calls to `readField()` and `writeField()` (issue #10 and #14) - * Added missing `ByValue` subclasses to `CvSeq`, `CvSet`, `CvContourTree`, and `CvChain`... Any others missing? - * Fixed `Exception` thrown from `cvCreateHist()` under JNA 3.2.7 (issue #26) - * Enhanced `CvMat.put()`, which now supports setting submatrices - * Improved inside `IplImage` the support of `BufferedImage`, especially those using a `DirectColorModel` (issue #23) - * Fixed crash in `cvkernels` when color transformation `X` is `null` - -### July 30, 2010 - * Fixed crash that would occur in `CanvasFrame` for some video drivers - * `FFmpegFrameGrabber` now supports other input formats (devices), such as `x11grab` that can be used for screencasting - * Added `JavaCV.median()` function, and `JavaCV.fractalTriangleWave()` now respects image ROI - * Fixed background subtraction in `cvaux` - * Fixed crash inside the code for direct alignment caused by the ROI getting set outside the image plane - * Added `deltaScale` and `tryToFixPlane` to `GNImageAligner.Settings` (the first used in `ImageTransformer.Parameters` as increment, randomly selected forward or backward, for finite difference), which sometimes help to jump over local minima - -### May 30, 2010 - * Removed redundant `CvMemStorage.clearMem()` method, use `cvClearMemStorage()` - * Fixed the sample `Test2` class that did not work under Windows - * Fixed corruption by the `cvkernels` `transformer` at the borders -

By contrast, the GNU General Public -License is intended to guarantee your freedom to share and change free -software--to make sure the software is free for all its users. This -General Public License applies to most of the Free Software -Foundation's software and to any other program whose authors commit to -using it. (Some other Free Software Foundation software is covered by -the GNU Lesser General Public License instead.) You can apply it to -your programs, too. - - When we speak of free software, we are referring to freedom, not -price. Our General Public Licenses are designed to make sure that you -have the freedom to distribute copies of free software (and charge for -this service if you wish), that you receive source code or can get it -if you want it, that you can change the software or use pieces of it -in new free programs; and that you know you can do these things. - - To protect your rights, we need to make restrictions that forbid -anyone to deny you these rights or to ask you to surrender the rights. -These restrictions translate to certain responsibilities for you if you -distribute copies of the software, or if you modify it. - - For example, if you distribute copies of such a program, whether -gratis or for a fee, you must give the recipients all the rights that -you have. You must make sure that they, too, receive or can get the -source code. And you must show them these terms so they know their -rights. - - We protect your rights with two steps: (1) copyright the software, and -(2) offer you this license which gives you legal permission to copy, -distribute and/or modify the software. - - Also, for each author's protection and ours, we want to make certain -that everyone understands that there is no warranty for this free -software. If the software is modified by someone else and passed on, we -want its recipients to know that what they have is not the original, so -that any problems introduced by others will not reflect on the original -authors' reputations. - - Finally, any free program is threatened constantly by software -patents. We wish to avoid the danger that redistributors of a free -program will individually obtain patent licenses, in effect making the -program proprietary. To prevent this, we have made it clear that any -patent must be licensed for everyone's free use or not licensed at all. - - The precise terms and conditions for copying, distribution and -modification follow. - - GNU GENERAL PUBLIC LICENSE - TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION - - 0. This License applies to any program or other work which contains -a notice placed by the copyright holder saying it may be distributed -under the terms of this General Public License. The "Program", below, -refers to any such program or work, and a "work based on the Program" -means either the Program or any derivative work under copyright law: -that is to say, a work containing the Program or a portion of it, -either verbatim or with modifications and/or translated into another -language. (Hereinafter, translation is included without limitation in -the term "modification".) Each licensee is addressed as "you". - -Activities other than copying, distribution and modification are not -covered by this License; they are outside its scope. The act of -running the Program is not restricted, and the output from the Program -is covered only if its contents constitute a work based on the -Program (independent of having been made by running the Program). -Whether that is true depends on what the Program does. - - 1. You may copy and distribute verbatim copies of the Program's -source code as you receive it, in any medium, provided that you -conspicuously and appropriately publish on each copy an appropriate -copyright notice and disclaimer of warranty; keep intact all the -notices that refer to this License and to the absence of any warranty; -and give any other recipients of the Program a copy of this License -along with the Program. - -You may charge a fee for the physical act of transferring a copy, and -you may at your option offer warranty protection in exchange for a fee. - - 2. You may modify your copy or copies of the Program or any portion -of it, thus forming a work based on the Program, and copy and -distribute such modifications or work under the terms of Section 1 -above, provided that you also meet all of these conditions: - - a) You must cause the modified files to carry prominent notices - stating that you changed the files and the date of any change. - - b) You must cause any work that you distribute or publish, that in - whole or in part contains or is derived from the Program or any - part thereof, to be licensed as a whole at no charge to all third - parties under the terms of this License. - - c) If the modified program normally reads commands interactively - when run, you must cause it, when started running for such - interactive use in the most ordinary way, to print or display an - announcement including an appropriate copyright notice and a - notice that there is no warranty (or else, saying that you provide - a warranty) and that users may redistribute the program under - these conditions, and telling the user how to view a copy of this - License. (Exception: if the Program itself is interactive but - does not normally print such an announcement, your work based on - the Program is not required to print an announcement.) - -These requirements apply to the modified work as a whole. If -identifiable sections of that work are not derived from the Program, -and can be reasonably considered independent and separate works in -themselves, then this License, and its terms, do not apply to those -sections when you distribute them as separate works. But when you -distribute the same sections as part of a whole which is a work based -on the Program, the distribution of the whole must be on the terms of -this License, whose permissions for other licensees extend to the -entire whole, and thus to each and every part regardless of who wrote it. - -Thus, it is not the intent of…
