摘要：
The distribution characters of the integer wavelet coefficients is discussed and the shortages of other existing wavelet compression algorithms are elaborated. Some kinds of images are processed by means of block adaptive zero-tree quantization. The experiments show that this method performs better than other existing wavelet image compression algorithms.
