Abstract
An apparatus include a processor and a coprocessor. The processor may be configured to track a plurality of positions of a plurality of maximum values in a plurality of images in a video signal. The coprocessor may have a circuit configured to (i) receive a plurality of sample values from the images and (ii) estimate the positions of the maximum values in the images. Each estimation generally includes a parabolic estimation operating on the sample values in a respective local region oriented parallel to an axis. The circuit may be implemented solely in hardware.
