Question about KLT Tracking

Hello everyone,

First of all, thanks in advance for all your answers.

I want to ask a question about my tracking code. At the beginning of my code, I get the coordinates of the object that is going to be tracked with below command:

objectRegion=round(getPosition(imrect));

This command enables me to get the region of the object from first frame. However, I want to get its coordinate at any time while image acquisition is running.

I have looked pause function and that kind of functions but I could not achieve to modify my code in the way that I want to.

I hope someone knows the solution of my problem.
