opencv3 class TrackerSamplerPF ERROR #1866
Description
When i using class TrackerSamplerPF,i get this error:
Error: Assertion failed (0 <= _rowRange.start && _rowRange.start <= _rowRange.end && _rowRange.end <= m.rows)
this is my code:
#include "opencv2/opencv.hpp"
#include "opencv2/tracking.hpp"
using namespace cv;
using namespace std;
int main()
{

// Exit if video is not opened
if (!video.isOpened())
{
cout << "Could not read video file" << endl;
return 1;
}
// Read first frame
Mat frame;
bool ok = video.read(frame);
// Define initial bounding box
Rect bbox;
vector<Mat> sample;
// Uncomment the line below to select a different bounding box
bbox = selectROI(frame, false);
// Display bounding box.
rectangle(frame, bbox, Scalar(255, 0, 0), 2, 1);
imshow("Tracking", frame);
vector<Mat> sampleImg;
Mat roi = frame(bbox);
TrackerSamplerPF *PFSampler = new TrackerSamplerPF(roi);
cout << PFSampler->getClassName() << endl;
while (1)
{
Mat new_frame;
video >> new_frame;
ok = PFSampler->sampling(new_frame, bbox, sampleImg);
//bool ok = true;
if (ok)
{
//Tracking success : Draw the tracked object
for (auto elem : sampleImg)
{
imshow("Tracking1", elem);
}
rectangle(new_frame, bbox, Scalar(255, 0, 0), 2, 1);
}
else
