Abstract
An apparatus include a first circuit and a second circuit. The first circuit may be configured to (i) receive a plurality of sample values from a plurality of images in a video signal and (ii) estimate a plurality of positions of a plurality of maximum values in the images. Each estimation may operate on the sample values in a respective local region oriented parallel to an axis. The second circuit may be configured to track the positions of the maximum values in the images.
