摘　　要：边缘检测是分割与处理图像的主要内容之一,广泛应用于医学、地理、化学等各大领域。图像不同的意思就是形状、大小各异。为提取图像的边缘信息中显示的特征像素点,分析四种边缘检测方法以及四种形态学的基本运算,并通过实验作出比较。Edge detection is one of the main contents of image segmentation and processing.It is widely used in medicine,geography,chemistry and other fields.Different images represent different shapesand sizes of image edges,that is,different pixels of feature points.Inorder to extract the feature points of image edge position,this paper introduces four edge detection methods and the application of four basic operations of mathematical morphology.
