Object Tracking OpenCV GPU / CUDA

Question

I'm trying to track objects very fast using my gpu. I've already done this one the CPU by

1. background Subtraction

2. contour Finding

3. Meanshift

But I cannot find anything in the OpenCV CUDA-Modul equal to the contour Finding algorithm. Background Subtraction works already very fast. Is there another way for object tracking using the GPU in OpenCV, CUDA Module?

Answer 1

You are right, there is no contour-finding algorithm in the CUDA module of OpenCV -because this algorithm is hard to optimize for the GPU.

But you could use optical flow . For doing this, you would have to find some features in the background-subtracted image; for example edges/corners or you could use GoodFeaturesToTrack, too.
