AN EFFICIENT AND ROBUST SCHEME OF IMAGE-CODING
一种高效的抗误码能力强的图像编码方案

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.
