Me and @dkurt trying to fix GOTURN tracker issues:

Memory issue.
The issue with taking ROI out of the image.

Hi! Please create a test with 2-3 images where we can catch observed error.

ieliz · 2020-07-30T13:01:30Z

Hi! Is it OK if I will use for reproducing the problem a video from the LaSOT dataset and provide drive.google link to it?

modules/tracking/src/gtrTracker.cpp

dkurt · 2020-07-31T08:11:29Z

You need to select minimal number of images where this error is reproduced. You need to open a separate pull request at https://github.com/opencv/opencv_extra/tree/master/testdata/cv/tracking (BTW, please check if existing videos can trigger it).

mshabunin · 2020-07-31T09:12:59Z

We should reuse existing videos if possible. Other way is to generate sequence of frames in the test.

ieliz · 2020-07-31T09:37:45Z

Sorry, but what do you mean by "generate a sequence of frames"? For reproducing I need a video, where an object is leaving the border of the frame, so it can not be random generated "dummy input".
So, which option do you mean?

Take a video sequence from the camera.
Create my own pictures.
Something else.

UPD: I looked at three existing videos in the repository:
https://github.com/opencv/opencv_extra/tree/master/testdata/cv/tracking
and there are no situations that cover the needed case.

mshabunin · 2020-07-31T10:26:33Z

For example, this generator: https://github.com/opencv/opencv_contrib/blob/master/modules/bgsegm/src/synthetic_seq.cpp, creates frames with waves on background and moving object (just an image) on foreground. It is used in some bgsegm tests.

Another example is here: https://github.com/opencv/opencv/blob/a2f7ef9d210e5be5741c6e3109c233672534a1ed/modules/videoio/test/test_precomp.hpp#L40-L58. It generates a sequence of frames with a moving background, static text and moving object (circle). Used in VideoWriter tests.

You can create similar generator (some static background) and an object (can be simple geometric figure) moving on whatever trajectory you want (leaving the frame).

ieliz · 2020-08-03T07:33:41Z

In the last few days, I tried again to use the videos from https://github.com/opencv/opencv_extra/tree/master/testdata/cv/tracking with 3.4 branch and find out that I was wrong in my last comment - with using tracker.py script, video "david" and 3.4 branch without any patches I successfully reproduced memory issue for GOTURN tracker.
Also, I have a suggestion about this PR - memory problem is related to GOTURN itself, but the ROI problem related to the benchmark. So, I think I should move ROI part of the patch in the tracker benchmark. Of all trackers in opencv-contrib, only the GOTURN tracker has ROI problem during initialization, but this case related to incorrect using of selectROI function (in ground-truth files of the LaSOT dataset exists bounding boxes with out of image coordinates). That fix in the benchmark should prevent the same problem for new trackers in the future.
I am so sorry for the inconvenience. What should I do in this situation?

dkurt · 2020-08-03T11:52:09Z

@ieliz , benchmark is nothing but one of possible tracker applications. Please fix a problem completely in this PR including a test. Thanks!

ieliz · 2020-08-03T12:03:10Z

OK, I will leave all changes in this PR.
But what should I do with the test now?

dkurt · 2020-08-04T10:22:26Z

@ieliz, you need to run an algorithm on this video as a test application. Add your code in https://github.com/opencv/opencv_contrib/tree/master/modules/tracking/test.

modules/tracking/test/test_trackers.cpp

modules/tracking/src/gtrTracker.cpp

ieliz · 2020-08-11T14:08:00Z

I think I make this test work, but I have some concerns.
First time I faced the problem with goturn.caffemodel and goturn.prototxt when I tried to start GOTURN tracker from opencv_contrib.
These files are absent in opencv_contrib and opencv_extra, so I was forced to download them from the other source.
Test and tracker would work if only we put these files into the current folder (opencv_contrib/modules/tracking/src or /samples , opencv/build_dir/bin).
My question to @mshabunin: what should I do in a situation like that?

UPD 12.08.20: Also, I think it is worth mentioning - it is necessary to add environment variable OPENCV_TEST_DATA_PATH (path to opencv_extra/testdata) for proper work of the tracker's tests (not only GOTURN test).

3.4

ieliz · 2020-08-14T13:49:04Z

Issue related to absent GOTURN models: #941. No answer about why models are absent in opencv_extra. Someone provides a link to models, but I do not understand why it is not in the master or 3.4 branches.

ieliz · 2020-08-14T15:35:43Z

To be sure, that all changes are working properly I rebuild opencv with opencv-contrib using 3.4 branches, tried to start C++ and Python 3 samples of the GOTURN tracker, start tests with and without fixes.
When we trying to launch tracker without fixes - we catch:

C++ exception with description "OpenCV(3.4.11-dev) /home/user/opencv/modules/core/src/alloc.cpp:73: error: (-4:Insufficient memory) Failed to allocate 85926161856 bytes in function 'OutOfMemoryError'
" thrown in the test body.

so if statement was redundant. My test is trying to run tracker on video from opencv_extra and if tracker trying to allocate too much memory - test is failed. I think it is enough for this kind of test.

For now, failed builds on win64 and win32:

@mshabunin , @alalek is it possible that these hosts do not have .prototxt and .caffemodel files for GOTURN tracker?
Test successful on Linux host and locally(Ubuntu 18.04).

alalek · 2020-09-04T14:00:25Z

@ieliz .caffemodel file is missing intentionally (due to wrong usage of test framework).
Commit 81b3c20 was green - check the difference.

ieliz · 2020-09-04T14:56:02Z

Commit was green, but the test was unfinished. So, green build for this commit is not significant.
There are many changes since then. Log for Linux is OK:

But Windows hosts can not find the file. Is it possible that files are not there?

alalek

Looks like you have broken serialization process.

Can't open ""

alalek · 2020-09-04T15:05:34Z

modules/tracking/test/test_trackers.cpp

+    "%YAML:1.0\n"
+    "---\n"
+    "prototxt: " + model + "\n"
+    "caffemodel: " + weights + "\n";


Avoid that. We don't testing parameters serialization here.

Use existed straightforward approach:

opencv_contrib/modules/tracking/test/test_trackerParametersIO.cpp

Lines 11 to 19 in e502f30

TrackerMedianFlow::Params parameters;

parameters.maxLevel = 10;

parameters.maxMedianLengthOfDisplacementDifference = 11;

parameters.pointsInGrid = 12;

parameters.winSize = Size(6, 5);

parameters.winSizeNCC = Size(41, 40);

parameters.termCriteria.maxCount = 100;

parameters.termCriteria.epsilon = 0.1;

But I implemented usage of the paths via cv::FileNode. So, this is gonna be no used for the test?

Test must be simple and straightforward.

this is gonna be no used for the test

At least not in this test with the name "memory_usage".

Please, check last changes:
I was forced to remove cv::FileNode, but instead used cv::TrackerGOTURN::Params params;, as @alalek said.
Win32/win64 builds are passed, so I think this test is ready.
