We present in this paper a new coding method for lossless gray scale image compression. Our method is based on modifications of LZ77-based compression and estimation of pre- diction errors of pixels and gives its C language implementation.
本文提出了一种用于无损灰度图象数据压缩新的编码方法──种基于对LZ77压缩方法的改进以及对图象元素预测误差的估计为基础的字典压缩方法，并给出了该方法的C语言程序实现。
