Abstract
A processor accesses a first video image and a second video image from a sequence of video images and applies a patch descriptor technique to determine a first portion of the first video image that encompasses a first person. The processor determines a location of the first person in the second video image by comparing keypoints in the first portion of the first video image to one or more keypoints in the second video image.
