基于数学形态学的图像边缘检测方法研究

在图像处理中,对于复杂图像的边缘特征信息很难通过一个结构元素来提取。笔者应用数学形态学的理论和方法,提出了一种选取多结构元素,采取排序边缘检测算法检测图像边缘信息,最后对不同结构元素的边缘检测结果求并,从而得到最终边缘图像输出的方法。实验表明,该方法具有较好的图像边缘检测效果,且简便灵活,可以适应不同类型图像的边缘信息检测需要。

Research Based on Mathematics Morphology Image Edge Examination Method

In image processing, it is very difficult to withdraw complex image edge characteristic information through a multi-structural element. This article applies mathematics morphology theory and method, brings up one kind of selected multi-structural element, adopts ordering edge examination algorithm to examine image edge information, finally asks to different structural element edge examination results and, thus obtains final edge image output method. Experiment indicates, this method has better image edge examination effect, also simple and flexible nimble, may adapt to different type image edge information examination necessity.
