Hello Berak,

One more time thank you. The problem is not to show various windows for each ROI, the problem is how to show window with only the selected ROI. For example, I select various "target" to track, using the MultiTracker algorithm. I need to show various windows which include only the ROIs selected by mouse. If I have three ROI with various size (Width and Height), I want to plot them on separated windows with the same ROI size.

Is it possible to achieve that ?

This is the complete code:

#include <opencv2/core/utility.hpp>

include <opencv2 tracking.hpp="">

include <opencv2 highgui.hpp="">

include <iostream>

include "samples_utility.hpp"

using namespace std; using namespace cv;
