现实生活中经常遇到所照图片清晰度不好,亮度不够,能辨率低,这样就需要将图像进行处理以得到清晰度和亮度更好的图像.文章首先介绍彩色图像和图像增强的定义与方法,以及彩色图像转换为灰度图像的方法,然后对直方图均衡化作出解释,最后通过实验先将彩色图像转换为HSI图像,并对HSI图像中的I分量的灰度图像进行直方图均衡化的处理,再将经过处理后的HSI图像还原成彩色图像,即可得到增强的彩色图像效果图.实现了通过直方图均衡化的处理得到彩色图像的增强.

In the real world, the photographs that were took, which are lack of clarity and brightness, and visibilities are low. So there is need to deal with these photographs to get better clarity and brightness of pictures. In the article, at first, recommending the definitions and measures of color images and image enhancement. And the ways of converting color images into gray scale im?ages. Then explaining what is histogram equalization. At last, through the experiments, converting color images into HSI images , and then getting the intensity image of HSI images that will be handled by histogram equalization, which will combines hue im?age and saturation image to get a HSI image which will be converted to color image that are final image. The results are achiev?ing the enhancement of color images by histogram equalization.
