摘要
本文分析了传统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,提出了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地保持图像细节,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 detail loss and noise amplification during image histogram equalization are analyzed in this paper. A new histogram equalization algorithm which can preserve image details is presented. Experiment results reveal that this new algorithm can enhance image contrast, preserve image details simultaneously, and can restrict image noise.
