| 摘 要： | 给出了一种新的无损压缩图像的编码方法。利用图像相邻像素点的灰度级连续和集中的特点，对灰度级进行分段编码，并用MATLAB编程实现，取得了很好的效果。其实验结果与哈夫曼编码做了比较，经过分析，此编码方法在灰度级概率均匀分布时具有优势。

| Abstract: | A new code method of compressing image without loss is presented. With continuous and concentrative character of gray scale of adjacent pixel, it was efficiently coded by segment to gray scale. And through implementing its program in MATLA8 language, there is very good effect. Experimental results were compared with Huffrnan code, and through analyzing, this code method has advantage when probability of gray scale is distributed equally. |
