灰度图像增强算法的改进与实现研究

Study on Modification and Actualization at Algorithm of Gray Image Manipulation

分析了传统灰度图像直方图均衡化算法的不足,讨论并实现了一种改进的直方图均衡化图像增强算法。该算法与传统的算法相比,给出了合适的映射关系,运算效果有很大改善,减少了图像信息的丢失,特别是对于质量较差的原始图像,采用该算法进行图像增强处理时,也可以取得较好的效果。

A modified algorithm of histogram equalization to gray image manipulation was discussed and actualized by analyzing principia and deficiency of the traditional algorithm of gray image.This modified algorithm contrast with the traditional algorithm,there are an apt mapping relation and much betterment at operation effect and image information.Especially it is adopted to process those poor quality images.
