摘要

本文根据人眼视觉对亮度和颜色不同的敏感特性

按照视觉特性选择了CIE La

均匀彩色空间

在此空间中提出了一种基于小波变换的彩色图像增强算法.和目前存在的灰度图像增强算法相比

本文不仅给出了一种自适应动态范围调节算法

同时对图像的饱和度分量也进行处理.实验证明

增强后的彩色图像不仅更加清晰

同时更加生动

鲜艳

达到了预期的目的.

Abstract

Based on the analysis of human visual system characteristics to brightness and color

we present a novel algorithm with considering about wavelet decomposition and color space for color image enhancement.The uniform color space CIE La b is used and a hybrid contrast enhancement algorithm for color image is proposed.Color image enhancement exists two goals:image looking naturally and looking vividly.Experimental results confirm that improved color image enhancement is achieved.
