摘　　要：首先利用给出的算法对图像进行Canny算子边缘检测,把图像转化成二值图像,然后对图像用数学形态学边缘检测去除伪边缘,最终再进行边缘连接.实验结果表明,对于含有噪声图像和不含噪声图像进行分割时,可以在尽量保留图像最大信息量的基础上,提取出单像素封闭边缘,保证了边缘信息的完整有效.First of all, it detects the image by canny edge detection, takes the received segmentation information as necessary reference information, Then you can rapidly and efficiently search for the best threshold with the algorithm of mathematical morphology therefore to handle the edge image, finally carry out the edge connection. The experiment indicates that it can obviously improve the quality of edge detection in this method compared with traditional methods. It remains the image information at most while picks the single - pixel edge quickly and precisely.
