摘要

本研究比较了Canny算子和Sobel算子对不同标志图像的边缘检测技术。主要过程涉及到Sobel和Canny边缘检测技术，使用捕获的标志图像和从互联网上获取的标志图像。对图像进行中值滤波去除噪声，采用Otsu方法确定阈值。结果表明，两种算子作为标识图像边缘检测辅助手段各有优缺点。

Evaluation of canny and sobel operator for logo edge detection

This study is to compare how Canny and Sobel Operators can be used as edge detection technique for various logo images. The main process involved Sobel and Canny edge detection techniques using captured logo images and logo images from internet. The images manipulated by median filtering to remove noise and Otsu's method is used to determine threshold value. The result shows that both operators have their own advantages and disadvantages to be used as edge detection aid for logo images.
