Algorithm of Image Compression Based on Orthogonal Wavelet Packet
基于正交小波包的图像压缩算法

This paper presents a new method of image compression,algorithms of image decomposition and reconstruction based on orthogonal wavelet packet are studied deeply,best basis of orthogonal,the method of selecting best basis in wavelet packets is introduced in detail,and simulated by using MATALAB7.The results show that it is an efficient compression method owing to a larger compression ratio,a less loss of information,and better performance of recovering the original image.
