Abstract
This paper introduces an improved variable size block based motion estimation algorithm relying on a hierarchy of motion representations. The most efficient of the latter is chosen through an evaluation constraint which models the total bit rate. The proposed coding technique exploits the concepts of temporal tracking and localization of the displaced frame difference energy. Moreover, only the smallest regions of the latter are coded and transmitted. Simulations show a significant improvement of the performances.
