Paper Abstract

In this paper, the hexagonal subband filter banks developed in [SIMO 90] are applied to motion video sequences by incorporating multi-resolution motion compensation and vector quantization. A bit allocation scheme is obtained in terms of both the vector variance distribution and correlation properties within a vector. A classified vector quantizer is used to quantize the motion-compensated residual subbands using a multiresolution codebook, which is obtained by training the corresponding subbands in the training sequence.
