摘要：
To compress image sequence, a coder structure, which combines the standard 3-D wavelet transform with motion compensation, has been introduced. For image sequence with slow motion, according to the characteristic of the wavelet transformed data, a new coding algorithm, which integrated the improved EZW(Embedded Zerotree Wavelets Encoding) and pixel coding, has been presented. Computer simulation shows that through the method not only the computational complexity is reduced but also even when the compress ratio gets 400:1, the recovered image quality still can gain more than 29dB.
