Abstract :
This paper studies wavelet transform coding for image sequence compression, the proposed coding method includes displacement estimation in the transform domain, quantization of transform coefficient difference values and a scheme of variable length coding. The computer simulation shows that wavelet transform coding has a superior performance in terms of free block-effects as well as subjective quality, compared to other transform coding methods
