opencv中trackerKCF 释放后程序不退出，内存不释放，这是为什么？

Question

#include "opencv2/core.hpp"
#include "opencv2/highgui.hpp"
#include "opencv2/tracking.hpp"

#include

#include

using namespace cv;
using namespace std;

int test(int argc, char* argv[])
{
Rect2d roi;
Mat frame;
Ptr trackers[100] ;

 VideoCapture cap("test.mp4");
int fps = cap.get(CAP_PROP_FPS);
cap >> frame;

roi = Rect2d(114, 114, 75, 75); //test
for (int i = 0;i<100;i++)
{
    trackers[i] = Tracker::create("KCF") ;
    trackers[i]->init(frame,roi);
}

int in = 0;
for (int index = 0;index<1000;index++)
{
    cap >> frame;
    if(frame.data==NULL)
    {
        printf("Video end--------.\n");
        break;
    }
    cv::Rect2d tmRect;
    for(int j = 0; j<100;j++)
    {

        start = clock();
        static int index = 0;
        index++;

        if(0!=index%10)
        {
            trackers[j]->update(frame,tmRect);

        } else
        {
            trackers[j] = TrackerKCF::create() ;
            trackers[j]->init(frame,roi);
        }

    }
    std::cout<<in<<std::endl;
    in++;

}
for(int i = 0;i<100;i++)
{
    trackers[i]->clear();
    trackers[i].release();
}
cap.release();
return 0;

}

int main(int argc, char* argv[])
{
int ret = test(argc,argv); //memory not free
return ret;
}

当test()返回后，内存没有释放，这是为何？
