模糊逻辑在图像增强算法中的研究及应用

提出了基于模糊逻辑和纹理分析的图像增强算法,通过图像模糊化、提取纹理信息和纹理信息模糊化、定义局部对比度、根据全局和局部信息来进行对比度的变换等措施,提高了增强算法的效果.测试结果表明该算法能很好地增强图像的边缘等细节信息,同时避免放大噪声和过增强的出现.

An Enhancement Algorithm Based on Fuzzy Logic and Texture Analysis

This paper presents a novel enhancement algorithm based on fuzzy logic and texture analysis.The approach improves the enhancement performance with image fuzzification,textural information extraction and texture fuzzification,local contrast definition,and contrast transformation by global and local information.Experimental results have proved that the proposed method has better performance in enhancing images without over-enhancement and under-enhancement.
