Abstract
A method includes tracking positions of object(s) in video frames, including: processing an initial frame of a set of frames of the video frames using feature extraction to identify locations of features of the object(s), obtaining a next frame of the set and applying a motion estimation algorithm as between the next frame and a prior frame to identify updated locations of the features in the next frame, where locations of the features as identified based on the prior frame are used as input to the motion estimation algorithm to identify the updated locations of the features in the next frame based one searching less than an entirety of the next frame. The tracking further includes recognizing occurrence of an event, halting the iteratively performing, and repeating, for at least one subsequent set of frames, the processing an initial frame and the using motion estimation.
