摘要
本文分析了常用的梯度算法,提出了针对灰度图像和彩色图像的改进思路,并编程实现这些算法。在RGB空间上实现的彩色图像边缘增强算法,可直接用于二值图像和灰度图像。改进后的算法简单易行,能有效地增强图像的边缘,具有较好的实用价值。
Based on the analysis of general gradient algorithms, this paper produce an new ideal to process gray images and color images and achieved them by programming. This new algorithm is to detect color images' edge in RGB color space, however, it can also process 2-value images and gray images directly. This algorithm is more simple than others, and effective to buildup images' edge. I think it have great applied value.
