OpenCL version HOG descriptors change among executions with same input
I output HOG descriptors of my input data use function HOGDescriptor::getDescriptors(). The descriptors change a lot when I run the program multiple times. Is this normal? If it is not, what could be wrong? Any advice is appreciated! Thank you!
The following are some example HOG descriptors:
