摘要：

In this paper, we propose an effective method for image coding using vector quantization (VQ) and wavelet transform. An efficient clustering algorithm is derived for codebook design using mean-squared error (MSE) and variance based selection strategy. The new technique is implemented in the wavelet-domain. Different subband coefficients are vector quantized using full search VQ and, adaptive dynamic finite state VQ (ADFSVQ). Computer simulation results axe presented to evaluate and compare the performance of the proposed scheme with other reported results.
