Abstract :
Summary form only given. In this paper, we describe a region-based video coding algorithm that is currently under investigation for inclusion in the emerging MPEG4 standard. This algorithm was incorporated in a submission that scored highly in the MPEG4 subjective tests of November 1995 (Talluri et al. 1997). Good coding efficiency is achieved by combining motion segmented region-based coding with the Shapiro´s embedded zero-tree wavelet (EZW) method
