Opencv Resize Image Gpu. To keep data in gpu memory opencv introduces a new class cv gpu gpumat or cv2 cuda gpumat in python which serves as a primary data container. Hackathon findings on the problem.
Computes the minimum eigen value of a 2x2 derivative covariation matrix at each pixel the cornerness criteria. The implementation is not the same as opencv uses for cpu kernels and it leads to different results.

I want to calculate the dense optical flow on gpu by opencv.
Gpu resize supports only 1 and 4 channel images. 11 stereo matching face detection surf. Hackathon findings on the problem. The implementation of cv cuda resize with linear interpolation does not use npp and is aligned with gpu texture unit implementation to reuse it for some cases.
