摘　　要：首先简要介绍了多分辨分析和Mallat算法,然后用其进行了医学图像压缩实验。实验表明,小波变换算法具有较高的压缩比和较好的图像恢复质量,不同类型的医学图像在同一小波基下压缩比不同。This paper firstly introduces multi-resolution and Mallat algorithm. Then, its application in medical image compression is experimpented. The result of the experiments shows that higher compression-ratio and better recovery image can be expected with this algorithm, and that the compression-ratios of different images are different using the same wavelet base.

关 键 词：多分辨分析 MALLAT算法 医学图像 压缩
