摘　　要：传真图像的信息量非常大,对其进行数据压缩,不仅可以节省存储空间,而且可以有效地降低传输时间。针对MR码,设计了一种编码和译码算法,并利用MATLAB软件进行实现;采用该算法对传真图像进行数据压缩,并比较MH编码和MR编码的压缩比,仿真实验表明,该算法可以满足传真图像对压缩比和压缩速度的要求,并证明了该算法的可行性。The quantity of information in a facsimile chart is huge.The data compression of charts can help us to save more storage space,and reduce the transmission time effectively as well.A code algorithm and decode algorithm are designed namely modified READ code.It is realized by MATLAB software.The emulative trial is put up for MH code and MR code finally.The results show that the algorithm can satisfy the requirements of compression ratio and speed.So it is proved to be feasible theoretically.
