I am trying to detect half and quarter circles. I found a stackoverflow question where the person used houghCircles to find the quarter and half circles, however that was in c++ and I have been unsuccessful in porting it into python. I was wondering if anyone has a easier solution to finding half and quarter circles in opencv python or some other function I can try using. Here is the photo I am using to try to recognize half and quarter circles for.

Do you already know the radius of the circles? Are the objects always seperated? What is the minimal size of the objects? Are other rotations possible?

I used these settings (C++ 2,100,35,20,100,200) and received these results in my Find Circles App that uses HoughCircles.
