Enhanced hierarchical motion estimator beyond Targeted Content

Abstract

A hierarchical motion estimator developed for Targeted Content applications has been extended from estimating the motion of some defined points of interest to providing motion vectors for all pixels in a frame. It includes an arbitrarily large search range, DFD-based segmentation (displaced frame differences) of the measurement window for improved results near distracting moving objects, enhanced search procedures, bidirectional and sub-pel motion estimation.
