Estimação de movimento com medidas de dispersão do resíduo de predição

— Block motion estimation is used in most video codecs to exploit temporal redundancy between frames. It usually evaluates some sort of distance metrics such as the SAD or the SSD between a candidate block and a target block. In this paper, we argue for the consideration of dispersion measures of the residue along with the usual distortion metrics. As a proof of concept, a method is devised to bring dispersion measures into consideration in the H.264/AVC JM reference software while keeping it absolutely compliant to the standard. Results show significant improvements over the original H.264 encoder.
