摘　　要：本文利用M通道小波变换对信号分频范围更细这一特点,实现了M通道小波变换的提升分解,并给出了一种M通道快速提升小波变换的算法。此算法只要有分解算法,立即可以得到合成算法,而且将运算结果取为最接近的整数,就可实现整数到整数的小波变换。数值实验结果表明,该方法对图像压缩行之有效。According to the M-channels wavelet transform theory and the suhdivided signals, we realize the lifting to M-channels wavelet transform, and give a new algorithm of M-channels fast lifting wavelet transform in this paper. The algorithm is so easy that it needs only the decomposition algorithm to obtain, the composition algorithm. However, the integerto-integer wavelet transform can be achieved when the operation result is the proximal integer. The algorithm is used in image processing. The experiment results show the algorithm is very effective for image compression.
