you can try to imagine vector<point> is a vector so vector<vector<point> is the vector of the vector,so it is a 2d matrix.

Hi, the code in the frist line creates a std::vector contours_poly containing vectors of points. The vector contours_poly is created with a size of contours.size(). More information about the constructors of std::vector can you see here.
