This version of transflow is a limited version of the Python one, only allowing for transferring optical from one webcam stream on the frames from another webcam streams. The optical flow is computed using Gunnar Farneback's algorithm.
- Download and compile OpenCV using this guide (this might take a while)
- Compile transflow.cpp linking OpenCV
Note
If you compile on something other than Windows, you might want to edit the line 14 to set the correct device API for your system. For instance, Linux users might want to use cv::CAP_V4L2 instead of cv::CAP_DSHOW.
Note
On Windows, you must put OpenCV DLLs in the same directory as the executable. On Linux this should not be an issue.
