基于空间变换和专家模糊技术的彩色图像对比度增强
Contrast enhancement of color image based on spatial transformation and expert fuzzy method
摘要
Abstract
The existing image enhancement algorithms have some disadvantages such as large computation,poor re-al-time performance,parameter selection difficulty,color drift,convergence guarantee and so on. As far as the effect of image enhancement is concerned,we mainly consider the visual perception of human eyes. And it is diffi-cult to process the image with accurate standards and methods. Therefore, fuzzy technology based on imprecise concept and expert experience is an effective method to solve the problem of image enhancement. In this paper,a color image contrast enhancement technique is proposed. Firstly, the color space of color image is transformed from RGB color space to the color space of hue,saturation and gray scale,and then the image enhancement is pro-cessed by expert fuzzy technology. The algorithm does not change the hue and saturation of the original color image. The contrast experiment shows that the method can improve the visual effect of the image significantly, and the computation is small and the real-time performance is excellent.关键词
