二值图像的游程法压缩及其改进算法

Run-length Algorithm of Black and White Image Compression and Its Improvement

依据游程压缩算法的基本原理,实现了对二值图像的无损压缩,并针对点阵汉字 库本身的特点,对算法作了进一步改进,压缩比有了较大提高?该算法实现简单,对计算时 间空间的要求低,适合嵌入式应用环境?

Using the principle of Run-length Algorithm, the paper realizes a lo ssless compression of black and white images. Then, using the character of Chine se word lattice, it gives an improved algorithm which has higher compression rat e. This algorithm can be realized easily, need few computation time and memory, and is adapted to embedded application.
