摘要
图像边缘检测通常是以类似于素描图的图像表达出物体的要素和特征,其任务是使图像边缘准确定位和抑制噪声。分析了两种基于数学形态学的边缘检测技术,即基于多尺度形态梯度的边缘检测和基于形态学多级平均的图像边缘检测,并对其进行了理论分析和比较,得出了相应结论。
The aim of image edge detection is usually to use images to sketch pictures to express the features and outlines of objects. Its task is to locate image edges exactly and reduce its noise. Two kinds of edge detection techniques based on mathematical morphology are analyzed： multi - scale morphologic edge detection and multi- grade mean morphologic edge detection. They are analyzed and compared theoretically, from which conclusions are drawn.
