In SIFT, how is the coordinate system being rotated?

I need to understand how SIFT calculates the descriptors for the keypoints. Intuitively, I understand that it takes each keypoint, calculates the gradients for each pixel in a neighborhood of the keypoint, and that's basically the descriptor for the…

What is the difference between face identification, face verification, and face recognition?

I am confused. On some websites, face identification is just face detection, while face verification is finding the person's identification. They are both considered components of face recognition. But in some websites face verification is 1-to-1…
