Hi everyone, After using InrangeS() function to seperate the green area from an image, I get a binary image contain white and black area. In white area, I don't know how to recognize that they're not circle or they're circle. I'm very grateful if everyone help me to solve this problem. I'll enclose the image I get after using Hough transform for everyone :) Thanks a lotC:\fakepath\image.png

Use HoughCircles. This method detects circles according to the criteria that you give it.

I think that what you are looking for is a shape detection algorithm. If you make a search in the internet I think that you will easily find several approaches. Have a look here to get an idea. I hope that it will help you.
