| 摘 要： | 介绍了比例变换，指出利用其对二维波形压缩时容易失真的缺陷，进而提出了用比例变换和插入特征点相结合的方法对波形进行无失真压缩的算法．首先提出了单波形无失真压缩算法，然后在此基础上又提出了多波形无失真压缩算法．两个算法都在VC中编程实现．

| Abstract: | The liner transform is introduced and its limitation to compress two dimensional waveform is pointed out, and then a solution of lossless compression for two dimensional waveform by combining liner transform and inserting key-point is proposed. The algorithms of lossless compression for single two dimensional waveform and multi two dimensional waveform are developed. The algorithms are programmed with Visual C++ language. |

| Keywords: | lossless compression liner transform key-point |
