| 摘 要： | 以CT、MRI等医学图像组为对象，研究一种基于小波变换的医学图像数据无失真压缩编码方法。利用小波变换实现图像的多分辨率分解．然后再对变换后的小波图像进行动态Huffman编码。最终实现压缩比较大的图像无失真压缩编码。实验表明．该方法在压缩比和重建图像质量上均达到了较好的性能。

| Abstract: | To find a wavelet-transform-based lossless compression coding method for CT and MRI images in the store and transmission of medical image. Wavelet transform was involved in multi-resolution dissection, and then dynamic Huffman code was performed to gain expected image. Experiment results showed that this method had advantages of a high compression ratio and a high image quality. |
