变换的直方图均衡算法在图像增强中的应用

The application of changed histogram equalization in image enhancement

常规直方图均衡化增强后的图像在高灰度区有过亮的感觉.为此,本文对常规的直方图均衡化算法进行了改进,采用变换的直方图均衡化算法抑制这一缺陷.实验结果表明,变换的直方图均衡化算法较常规算法具有更好的效果.

The image enhanced by traditional histogram equalization is over-bright in the high gray area. The changed histogram equalization can save it. It is an amelioration of the traditional histogram equalization. The result of experience appear that it is more effected than traditional method.
