Step 6 will explain how we can determine which weak edge is an actual edge. This threshold is different per image so I had to vary the values. In my implementation I found it helpful to choose a threshold ratio instead of a specific value and multiple that by the max pixel value in ...

8. Edge Detection 边缘检测也是图像处理中的一个基本任务。传统的边缘检测方法有基于梯度 算子,尤其是 Sobel 算子,以及经典的 Canny 边缘检测。到现在,Canny 边缘检 测及其思想仍在广泛使用。关于 Canny 算法的具体细节可以在 Sonka 的书以及 canny 自己的论文中找到,网上也可以搜到。最快最直接的方法就是看 ...
The Gaussian mask used in my implementation is shown below. 为了进行边缘提取,需要做一些预处理。第一步要进行滤波来滤去噪声。因为高斯滤波采用一个简单的掩码,所以它通常应用于Canny算法。一旦一个合适的掩码被确定,高斯滤波就可以进行标准的卷积计算。一个卷积往往要小于原始图像。因此,掩码要在原始图像上滑动,...
