Hierarchy为可选输出变量,是std::vector<cv::Vec4i>类型的向量(每个元素都是一个4个int值构成的向量)。包含有关图像拓扑的信息。它具有与轮廓数量一样多的元素。例如,第i个轮廓, hierarchy[i][0],hierarchy[i][1],hierarchy[i][2]和hierarchy[i][3]依次为:第i个轮廓的[Next, Previous, First_Child, ...
输出:检测到的轮廓。每个轮廓都存储为点向量(例如std :: vector <std :: vector <cv :: Point >>)。即由若干个cv::Point类型的点组成了单个轮廓std :: vector <cv :: Point >,再由若干个轮廓组成输入图像中的全部轮廓std::vector<std :: vector <cv :: Point >> ...

Basically to make this efficient, you need to create a cdef class that stores the std::vector< std::vector<npy_intp> > internally and (optinally) return this to Python instead of a list. Then your Cython code that uses cKDTree.query_ball_tree could grab the jagged array from this class...
