Rate-distortion based optimization for zerotree entropy wavelet coding

We present a rate-distortion (R-D) based bit allocation scheme for MPEG-4 zerotree entropy based wavelet coding, specifically, the multiscale zerotree entropy coding mode (MQ) of the MPEG-4 visual texture coding tool. With an iterative quadratic R-D model, our algorithm achieves accurate target bit rate and better image quality with fast convergence.
