OpenCV 2.3:如何将每个轮廓的所有孔放入子向量中

对于每个轮廓，我想把它的孔放入单独的矢量<>的洞。默认在OpenCV 2中。*我们有两个选择-使用OpenCV 1。*树形结构并迭代它，如本教程所示，让我们的头围绕vector<Vec4i>，这是有点简化，但相同的OpenCV 1.0类似的树形结构，它依赖于std::vector< std::vector<Point> >，你可以从findContours获得。当你需要了解继承——"什么被放在什么里面"时，树是很有用的。但通常你只需要一组区域和它的洞。(用于向量化和类似任务)。

目前我有这样的代码:

#include <opencv2/opencv.hpp>
using namespace cv;
int main(  )
{
    Mat black = Mat::zeros(Size(100, 100), CV_8UC1);
    for(int i = 0; i <= 35; ++i)
    {
        for (int k = 0; k <=35; ++k)
        {
            black.row(i).col(k) = 255;
        }
    }
    for(int i = 10; i <= 15; ++i)
    {
        for (int k = 10; k <=15; ++k)
        {
            black.row(i).col(k) = 0;
        }
    }
    for(int i = 25; i <= 30; ++i)
    {
        for (int k = 25; k <=30; ++k)
        {
            black.row(i).col(k) = 0;
        }
    }
    for(int i = 45; i <= 75; ++i)
    {
        for (int k = 45; k <= 75; ++k)
        {
            black.row(i).col(k) = 255;
        }
    }
    for(int i = 55; i <= 65; ++i)
    {
        for (int k = 55; k <=65; ++k)
        {
            black.row(i).col(k) = 0;
        }
    }
    for(int i = 57; i <= 62; ++i)
    {
        for (int k = 57; k <=62; ++k)
        {
            black.row(i).col(k) = 255;
        }
    }
    namedWindow("Display Image", CV_WINDOW_AUTOSIZE);
    imshow("Display Image", black);
    std::vector< std::vector<Point> > contours;
vector<Vec4i> hierarchy;
if(sum(black).val[0] > 0.0)
{
    findContours(black, contours, hierarchy, CV_RETR_CCOMP, CV_CHAIN_APPROX_SIMPLE);
}
else
{
    std::cout << "It's a black image, so I'm not going to do anything..." << std::endl;
}
for(int i = 0; i < contours.size(); ++i)
{
    std::cout << "counter " << i << ":" << std::endl;
    std::cout <<  hierarchy[i][0]  << " "  << hierarchy[i][1] << " " <<  hierarchy[i][2]  << hierarchy[i][3]  << std::endl;
    for (int k = 0; k < contours[i].size(); ++k)
    {
        std::cout << "t point " << k << " x: " << contours[i][k].x << "; y: " <<  contours[i][k].y << std::endl;
    }
}
    waitKey(0);
    std::cin.get();
    return 0;
}

我想知道是否有可能将std::vector< std::vector<Point> > contours;更改为类似std::vector< std::pair<std::vector<Point>, std::vector<std::vector<Point> > > contours;的东西，其中对由其孔的轮廓矢量组成。它是可能的，以及如何实现这样的事情与openCV 2.3?

我的意思是像这样的东西(糟糕的，糟糕的C风格…)代码片段我创建:

struct vector_object
{
    std::vector<Point> border;
    std::vector< std::vector<Point> > holes;
};
std::vector<vector_object> container;
void store_vector_hole(std::vector< std::vector<Point> > &holes, std::vector< std::vector<Point> > & contours, std::vector<Vec4i> & hierarchy, const int & cid);
void store_vectror_countors(std::vector< std::vector<Point> > & contours, std::vector<Vec4i> & hierarchy, const int & cid);

void store_vector_hole(std::vector< std::vector<Point> > &holes, std::vector< std::vector<Point> > & contours, std::vector<Vec4i> & hierarchy, const int & cid)
{
    holes.push_back(contours[cid]);
    if (hierarchy[cid][2] >= 0) // holes in holes == real poligons
    {
        store_vectror_countors( contours, hierarchy, hierarchy[cid][2]);
    }
    if (hierarchy[cid][0] >= 0) // holes on same level of depth == another holes of this poligon
    {
        store_vector_hole(holes, contours, hierarchy, hierarchy[cid][0]);
    }
    return;
}
void store_vectror_countors(std::vector< std::vector<Point> > & contours, std::vector<Vec4i> & hierarchy, const int & cid)
{
    if (hierarchy[cid][0]>= 0)
        store_vectror_countors(contours, hierarchy, hierarchy[cid][0]);
    vector_object current;
    current.border = contours[cid];
    if ((hierarchy[cid][0]<= 0) && (hierarchy[cid][2] <= 0))
    {
            container.push_back(current);
            return;
    }
    if(hierarchy[cid][2] >= 0) // h
    {
        store_vector_hole(current.holes, contours, hierarchy, hierarchy[cid][2]);
    }
    container.push_back(current);
    return;
}

:

//...
findContours(black, contours, hierarchy, CV_RETR_TREE, CV_CHAIN_APPROX_SIMPLE);
store_vectror_countors(contours, hierarchy, 0);

有什么想法让它更健壮，更像c++吗?
