At present, binary image compression is still in the stage of lossless encoding with low compression ratios.

目前，二值图像压缩主要采用无损压缩方式，压缩倍数低。

This paper describes these static image compression standards and encoding processes separately and compares the lossless compression feature of the processing of clinic static images.

本文分别介绍了这三个静止图像压缩标准和编码过程，并对三种压缩标准在处理临床静止图像的无损压缩性能方面做了比较。
