Abstract :
Based on the ideas of zerotree coding, vector classification, trellis coded quantization and small-size codebook expansion, the paper proposes a new encoding method of two-dimensional trellis coded vector quantization (2D-TCVQ) of a wavelet image with tree-structure vector combination and classification. Simulation results show that this method could achieve good compression results, and it has moderate encoding complexity and low decoding complexity. Also, the method is insensitive to channel error pervasion.
