| 摘 要： | 背景:医学数字图像必须是高质量的、高分辨率,所以数据量很大,如此巨大的数据量不利于图像存档与传输系统的运行和数字化医院、远程医疗的实现.因此,图像压缩成为图像存档与传输系统要解决的重要问题.目的:分析零树小波变编码算法原理并编程实现对医学数字图像的压缩,使之能够满足医学图像的传输和诊断要求.方法:应用嵌入式零树小波编码算法,探讨小波基和小波变换层数的选择,编程实现对医学数字图像的压缩.结果与结论:选择双正交小波基对医学图像进行4层小波变换实现压缩,获得了较高的峰值信噪比,取得了较好的压缩效果.

| Abstract: | BACKGROUND:Medical digital image must be a high-quality,high resolution,large amounts of data.Such an enormous amount of data is not conducive to the operation of Picture Achieving and Communication System(PACS)and digital hospital,telemedicine implementation.Therefore,image compression becomes an important issue to PACS.OBJECTIVE:To analyze the zero-tree wavelet coding algorithm and program for the medical digital image compression,to enable it to meet the medical image transmission and diagnostic requirem... |
