Example of SparsePyrLKOpticalFlow

asked 2017-06-02 21:26:13 -0600

Hello,

I'm trying to refactor old code which uses "cvCalcOpticalFlowPyrLK" (http://docs.opencv.org/2.4/modules/vi...). With new cuda function cv::cuda::SparsePyrLKOpticalFlow::calc but I cannot find any example of usage.

Can anyone please post me some example of correct use of this method, (of all the input structures and what should I receive)?

Thanks a lot

It is essentially the same as the non-CUDA version, with the exception of the image input types, which should be CUDA Mats. You can see a bit of sample code HERE.

How can I use a FAST_GPU function to detect the features and then use PyrLKOpticalFlow? The GpuMat format that is returned from FAST_GPU is of a different type than the one Pyr LK Optical Flow accepts.
