直方图均衡化图像增强的改进算法

摘要

An improved algorithm of histogram equalization for image enhancement is discussed. After the image containing noises was wavelets transformed, the low frequency wavelet coefficients are equalized, and then all the wavelets are inverse transformed to enhance the image. This improved algorithm of histogram equalization gets a better image enhancement effect by test verification.%探讨一种直方图均衡化图像增强的改进算法.对图像进行小波变换后,对低频小波系数进行均衡化处理,再小波反变换获得增强图像.结果验证,基于直方图均衡化图像增强的改进算法,获得了较好的图像增强效果.
