【摘要】 近无损图象压缩是近年来发展较为迅速的一门技术 ,由于其压缩效率较低 ,通常的压缩方法难以实现实时性。采用 JPEG LS框架结构 ,对系统软件进行了研究 ,通过实际测试 ,该方法平均压缩率可达原图象的35 % ,并且能够实时处理更多还原

【Abstract】 Closelossless image compression is a highly developing technology in recent years.Due to its low rate compression,the normal method of compressing can not been used to meet the demand of realtime.In this paper,the frame construction of JPEGLS is used,and the software of system is studied.A ccording to practical test.The average rate of image compression can be 35 percent of the original image by this method,and can be done in realtime.更多还原
