摘　　要：本文分析了传统的灰度图像直方图均衡化算法的不足,提出了一种基于概率的灰度图像直方图均衡化的改进算法。该方法给出了较合理的变换关系,使运算结果有较大改善,而且保留了传统算法的快速、自动化的特点。The disadvantage of traditional histogram equalization is analyzed in this paper, and a new improved method is put forward based on probability of histogram equalization. It is proved that this method gives a better conversion, not only can make the result a great progress but also can be as fast and automatic as the traditional one.
