Abstract

Recently a number of new low bit-rate block-based video-coding algorithms have been reported that focus on moving objects by dividing the macroblocks into three classes based on motion involved. In the conventional H.26X coding standards, macroblocks are divided into static (no motion) and active (with motion) classes. These new algorithms have improved coding efficiency as well as corresponding picture quality by separating a sizable number of active macroblocks, which posses significant static regions, into a new active-region class. A small number of fixed regular shaped patterns are used to represent the moving region in an active-region macroblock. In this paper, we examine a number of alternative definitions for classifying macroblocks, and propose, for the first time, a parametric definition based on the number of moving pixels in a macroblock. Experimental comparative results clearly show that this new macroblock parametric definition outperforms the old definition in improving coding efficiency without degrading the subjective quality
