Wavelet transform coding for image sequence compression

摘要

This paper studies wavelet transform coding for image sequencencompression, the proposed coding method includes displacement estimationnin the transform domain, quantization of transform coefficientndifference values and a scheme of variable length coding. The computernsimulation shows that wavelet transform coding has a superiornperformance in terms of free block-effects as well as subjectivenquality, compared to other transform coding methods
