Hey so i found a python code on the internet, and i found it runs really good, but i wanted it to be faster so i tried to translate it to C++. I did and it works , it draws rectangles on a separate window like in python but it cant find some things… the python version can and i put them side by side and in python it worked. I dont know what is the problem because i wrote the same function calls in C++ , and i thought someone more experienced with both versions may help me.

I installed Python 3.8.5 + modules tkinter and OpenCV.
