Abstract: This article explaines the basic part of JPEG image compression algo rithm. JPEG2000 image compression algorithm provides many new features against s tandard JPEG algorithm as well as improved compression rate and efficiency. Ba se d on its characteristics and the status of the Internet, it will have clear p ros pect in its application in network and other area.
