如何在OpenCV中实现等效于bwmorph Matlab函数的函数

Question

我想在OpenCV中实现bwmorph（图像，'端点'）函数。我检查了它的Matlab源代码。它使用查找表进行搜索。不幸的是，我找不到更多的细节，因为细节在C.中实现。 还有一个类似的问题：bwmorph(image,'clean') equivalent in opencv。 但它没有任何帮助。 任何人都可以告诉我如何在C++中使用OpenCV做到这一点？

Answer 1

我实现了您要查找的功能：

#include <iostream> 
#include <vector> 
#include <stdio.h> 
#include <stdarg.h> 
#include "opencv2/opencv.hpp" 
#include "fstream" 
#include "iostream" 
using namespace std; 
using namespace cv;

// LUT for skeletonization
