摘要
图像边缘检测是图像处理和模式识别领域研究的重要课题.介绍了几种经典边缘检测算子,对其性能和算法特点进行了分析.运用Matlab进行了算法的仿真,结果表明LOG算子比Sobel和Prewitt两个算子检测出的图像边缘更为连续,也比较细小.
Image edge detection is an important subject of research in the field of image processing and pattern recognition.The paper introduces several classical operators of edge detection,and analyzes the capability and characteristica of the edge detection operators.The algorithm is simulated by Matab.The conclusion is that LOG operator can detect more continuous and thinner image edges than Sobel operator and Prewitt operator.
