红外图像几种边缘检测算法对比分析

摘要

文章对Robert、Sobel、Prewitt、Log和Canny 五种边缘检测算子原理进行分析，并将其应用于红外图像边缘检测，对比了检测中出现的问题，分析其对应的理论基础，总结不同算子的检测效果，为红外图像边缘检测算子的选择提供了理论依据。%The paper study on Robert, Sobel, Prewitt, Log and Canny algorithm principle, and ap-plied them in infrared image edge detection, and also analyses the corresponding theoretical of different algorithms, compared the detection problems and detection effect, all those provides a theoretical selec-tion for infrared image edge detection.
