Thresholding is used to segment an image by setting all pixels whose intensity values are above a threshold to a foreground value and all the remaining pixels to a background value.
Whereas the conventional thresholding operator uses a global th

1。将Canny边缘检测器应用于灰度图像，得到二值边缘图。
2。从边缘图中提取边缘轮廓，填补等高线上的空白。
三.计算每个轮廓的低曲率以保持所有真实的角，所有曲率的局部极大值被认为是初始角点。
4。使用自适应局部阈值来去除初始角点，以去除圆角。
5。角候选的角度进行评估，以消除任何虚假角落由于量化噪声和琐碎的细节。上述评价基于一个动态的支持区域，该区域根据其相邻的角候选对象进行更改。
6。轮廓线的端点被认为有附加的标准。(1. Apply the Canny edge detector
