I have a question concerning the SURF_CUDA algorirthm. I want to detect the features of some frames in order to stitch them in the end. Therefore I need to compute the keypoints and descriptors. But the results are different on every execution, although the images are the same. How is that possible? I checked if the keypoints position are changing on every execution and I figured out they do change, even if its not a big change. But because of that I get different results for Homography. Does someone know how to stabilze the algorithm? Thanks in advance.
SURF_CUDA every execution compute different keypoints
