提出基于拉普拉斯高斯（Laplacian of Gaussian，LoG）算子边缘检测的全局二值化方法对其进行处理，该方法通过提取图像边缘部份的像素灰度获得图像二值化的阈值。处理结果表明，与传统的几种方法相比，该方法能够快速选取良好的二值化阈值，较好地区分目标和背景，在相当大模板宽度内图像二值化的结果都令人满意。-Is put forward based on the Laplacian of Gaussian (LoG) Laplacian of Gaussian, operator edge

自己写的python canny算法，可以对图片进行边缘检测，要求见PPT,可根据需要调整代码-Write your own python canny algorithm that can detect the edge of the picture, asked to see the PPT, the code can be adjusted as needed
