一种小波变换图象无失真编码方案

A New lmage Distortionless Compression Scheme Based on Wavelet

    摘要
  • 摘要: 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Huffman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.

     

    Abstract: Based on the characteristic of wavelet,a scheme for image data lossless compression is presented.In this method,we adopt a fast way——dynamic huffman code-to compress wavelet image data.Experiment results show that this method will achieve high quality reconstructed image in very low bit rate.
