摘要
边缘检测是边界图像分割的一个关键步骤。传统的边缘检测常用一阶和二阶导数来求解,本文提出了一种基于双结构元素的检测方法,以数学形态学为理论基础,以小结构元素递推出大结构元素,并将大小结构元素复合求取最终边界。通过实验对比分析表明该方法能够较好地获取边界信息。
Edge detection is a key step of image segmentation.The traditional edge detection is achieved by using first or second order derivative.This paper presents a new detection method based on dual structure elements.First,the small structure element is used to deduce the big structure elements.Second,the dual structure is compounded to attain the edge information.The experiment result indicates that this method is proved to be able to obtained better edge information.
