彩色图像局部自适应对比度增强算法研究

图像增强是大多数图像处理技术的前提工作,对于彩色图像,既要达到图像增强的目的又要保持色调不变成为一个难点。在研究RGB颜色空间和HSV颜色空间特点、数学形态学图像处理技术的基础上,在HSV颜色空间把一种灰度图像对比度增强算法推广到彩色图像处理算法。实验结果表明,该算法在局部自适应增强图像对比度的同时,能够保持图像色调,提高图像质量。

Tone Color Images Maintained Locally Adaptive Contrast Enhancement Algorithm

Most of the image processing techniques are based on the image enhancement operation, but the dodgy problem in the enhancement of color images is to enhance images without changing their original hue. The present research aims to introduce one of the solutions to this problem. Based on the study of the characteristics of RGB color space, the HSV color space, and mathcmatica/ morphology image processing technique, this article presents a solution to the problem by extending grey-level image contrast enhancement algorithm to the color image in HSV color space. The experiment results show that this algorithm can keep the original hue and enhance the quality of images while maintaining the adaptive contrast enhancement in local parts.
