| Abstract: | In this paper, a vector quantization algorithm based on biorthogonal wavelet transform is put forward. The corelation of the wavelet coefficients amony different scales is fully utilized and the Self-Organizing feature map neural network is used. The results of expriment show that high coding efficiency and reconstructed image quality are both obtained. |
