摘要
用Robert、Sobel、Prewitt、Laplacian、LoG和Canny算子,对图像进行了边缘检测实验,分析了边缘检测的结果,得出Canny边缘检测算子,是图像边缘检测的一种十分有效的方法。然后,根据图像的Canny算子边缘信息,将最佳全局阈值法与局部阈值自适应法在边缘信息的基础上融合起来,对图像进行了二值化处理。实验表明此算法在二值化图像时,能很好的保留图像的边缘信息。
This paper takes Robert,Sobel,Prewitt,Laplacian,and Log and Canny operator to detect image edge.The results of edge detection show that canny operator is the most fit to detect the image edge.Then,according to the results of edge detection with canny operator,authors carry out image binarizing process which combined the optimal global threshold and local adaptive threshold on the basis of edge feature.By using Canny operator,the results show that the method is available to treat images in a high level quality.
