摘　　要：文章提出一种游程编码和Huffman编码相结合的二值图像无损压缩算法,并对算法进行不同图像的仿真实验,实验结果证明本算法对分块清晰,纹理较少的二值图像压缩效果明显,算法实现简单,具有一定的实用价值。In this paper, a tossless compression algorithm in binary image based on run-length and Huffman coding is proposed. Different image is tested by the algorithm, and the experiment results indicate that this method can perform well at images of clearer block and less texture. Moreover, the algorithm is easy to accomplish and has practical value in binary image applications.
