问题描述
我读了一篇有关三角符号检测的研究论文，该论文先使用canny edge detection，然后应用Ramer-Douglas-Peucker从图像中检测出三角形符号，如下图所示.
I read a research paper about triangular sign detection that used canny edge detection and then applied Ramer-Douglas-Peucker to detect the triangle shaped sign from an image, like in the below photo.
我设法为图像应用了canny edge detection，但是我非常困惑如何应用Ramer-Douglas-Peucker来获得如上图所示的输出结果.
I managed to apply canny edge detection for my image, but i am super confused how to apply Ramer-Douglas-Peucker to get output results like in the above photo.
推荐答案
Douglas-Peucker算法可用于简化行.意思是它使直线几乎是笔直的.看看
The Douglas-Peucker algorithm can be used for line simplification. Meaning it makes lines which are almost straight, straight. Have a look at
如果您想了解它.
因此，该算法可帮助您消除噪音.关于三角形，除了它们具有直线之外，没有其他具体说明.
So the algorithm helps you by removing noise. It's nothing specific about triangles, except that they have straight lines.
