A Wavelet Transform based Image Coding Method Using Vector Quantization

摘要

Wavelet based vector quantization (VQ) image coding methods have raised the attention from many scholars in recent years. In this paper, beginning with a discussion of the shortcomings of such kind of image coding systems, a new VQ image coding scheme is put forward that can match very well both characteristics of human visual system and wavelet images. Results of simulation quantify its efficiency.
