摘要

Abstract

A new wavelet-based image-coding scheme was proposed. The Variable-Coefficient Fixed-Length(VCFL) Coding method was used to code the wavelet subband coefficients of the image. The codebook was obtained from symbol probability. By a way similar to Atithmetic Coding, a bunch of symbols was mapped to the code in the codebook. Several error-concealement methods were also adopted to improve the robustness. Simulation results show that our new scheme has higher compression ratio and robustness.
