摘要
分析了传统的直方图均衡算法导致图像细节信息丢失和噪声放大的问题,提出一种新的直方图均衡算法,能够在增强图像整体视觉效果的同时,较好的保持图像细节,对图像噪声也具有一定的抑制作用。实验结果表明,该算法具有较好的性能。
The problems of image details losing and noise amplifying during image histogram equalization are analyzed. And a new histogram equalization algorithm which can preserve image details is presented. Experiment resuits reveal that this new algorithm can enhance the image contrast and perverse the image details simultaneously, being immune to image noise.
