Abstract
In this paper, we present a rare-distortion (R-D) based bit allocation sche me for MPEG-4 zerotree entropy based wavelet coding, specifically, the Mult iscale Zerotree entropy coding mode (MQ) of MPEG-4 Visual Texture Coding to ol. With an iterative quadratic R-D model, our algorithm achieves accurate target bitrate and better image quality with fast convergence.
