Circle- Detection with Visual Basic

asked 2013-03-27 13:18:43 -0500

Hello, i want to detect multiple circles with my Webcam. I use Visual Studio Express 2010.

After the detection I want to see the absolute coordinates from the center point of each Circle. Furthermore I want the name of the colour. Is this with OpenCV in Visual Studio 2010 possible?

Please help me.

Thanking you in anticipation Freddy31

To find circles in an image, you can use the Hough transform for circle, where the output is (x,y,radius) for each circle. Since you have the center, you could find the color of that point if it's what you want.
