摘　　要：作者详细地介绍了一种基于人类感知的医学图象压缩算法，它利用人类视觉的运动特性，空间频率特性及时间频率特性对静止灰度图象进行有限失真压缩，该方法能大大压缩图象数据提高压缩比，对医学图象的压缩是一种比较有效的方法。An algorithm of medical image compression based on human perception, is described in this paper. The motion character, spatial frequency character and time frequency character of human vision are used to compress static image with limited distortion. The image date can be compressed greatly with this method, and compression ratio can be increased. It is a very effective method for medical image compression.
