提出一种基于小波变换的图象数据无失真压缩编码方法，基本思路是利用小波变换实现图象的多分辨率分解，然后再对变换后的小波图象进行动态Ｈｕｆｆｍ ａｎ 编码，从而在不影响整个系统运行深度的前提下，最终实现压缩比较大的图象无失真压缩编码。
This paper presents a lossless compression coding method of image data based on wavelet transform. The basic idea is to use wavelet transform to realize the multi-resolution decomposition of the image. Then the Huffman coding of the transformed wavelet image is carried out without affecting The entire system under the premise of the depth of operation, the final compression ratio to achieve a larger image without distortion compression coding.
