Hough Circle with trackbars [closed]

edit

There are a few parameters in the HoughCirclefunction. Is there a way to use the trackbars to change these parameters? so that I would not need to run the program every time i want to change them.

Thank you.

I have the cout expression to help me with locating the bug. In the window, it is showing like this enter image description here

And there is a problem with the HoughCircle function.

The code stops at number 2, and after like 10 seconds, it jump to 3 and loop over. I can't see what is the problem. The ... (more)
