摘要
分析了传统边缘检测中对边缘定义的不足 ,提出了一种新的彩色边缘定义。根据此定义提出了一种基于区域色度、明度等彩色信息区分度的边缘检测方法 ,并将实验结果同传统的Sobel方法进行了比较。结果表明 ,该方法充分利用了图像的彩色信息 ,获得了令人满意的效果 ,同时具有较好的抗噪能力。
In this paper, the addressing based on the traditional definition of edge detection, we proposes a method for edge detection which is based on the approximation degree of purity, brightness etc. The experiment result and comparisons show that this method applying the color feature fully and its robustness performance in the presence of noise over the technique of Sobel′s.
