I am doing a multiple faces detection & tracking. But the trackers are not updating properly.
The code runs without errors when compiling. During runtime I get the below message (not error tho)
''Trackers are initialized correctly.
unable to track"
Here is the code:
// Detect faces
std::vector faces;
Rect2d face_rect2d;
face_cascade.detectMultiScale( image, faces, 1.2, 2, 0|CV_HAAR_SCALE_IMAGE, Size(min_face_size, min_face_size),Size(max_face_size, max_face_size) );
for(unsigned int i = 0; i < faces.size(); ++i)
{
face_rect2d = faces[i];
rectangle(image,face_rect2d, Scalar( 255, 255, 0 ), 1, 4 ); // Draw the detections
Ptr tracker = Tracker::create( "MEDIANFLOW" ); // Create tracker
if (tracker.empty())
{
std::cerr << "***Error in the instantiation of the tracker...***\n";
return -1;
}
// Check if they are initialized
if (!tracker->init(image, face_rect2d))
{
std::cerr << "***Could not initialize tracker...***\n";
return -1;
}
else
{
std::cout << "Trackers are initialized correctly." << std::endl;
}
// Check if they are updated
if (!(tracker->update(image, face_rect2d))) {
printf("unable to track\n");
}
cv::rectangle(image,face_rect2d, cv::Scalar(255, 0, 255), 2, 1);
}
