摘要
介绍了二值图像的顺序形态变换基本概念 ,定义了两种基于顺序形态滤波的广义边缘算子 ,重点讨论了百分位 p=1 /2时的边缘算子抑制噪声、提取边缘的理论和方法。实验表明 ,同传统的边缘检测算子相比 ,该方法具有良好的噪声抑制、边缘提取特性。
First, Basic conceptions of order morphology transformation on binary image are introduced, then two generalized edge operators based on order morphology filtering are defined, Finally the theory and method of the edge operator when percentile p is equal to 1/2 are dealt with for noise suppression and edge extraction. The experiments show that this method possesses good characteristic of suppressing noise and extraction edge comparing to common edge extracting method.
