The region histogram equalization is different from traditional histogram modification technology, the idea is based on human vision character and edge effect in image vision.

区域间直方图均衡不同于传统的直方图修正技术，该思想是充分地考虑到人类的视觉特性和边缘在图像视觉中的作用而提出的。

Compared with traditional histogram equalization method, the new algorithm not only reserved the visual characteristics of bright region, but also make noise enhancement relative weak.

与传统直方图均衡化增强方法相比，该方法保留了较亮区域的视觉特性，且对噪声的增强相对较弱。
