Hi, nice one. Could I ask how you can detect multiple circles?

Thanks

when you create CvMemStorage structure you can use CvSeq structure variable to get access to all circles that have been found.

i.e

CvSeg *circ = cvHoughCircles(...);

then put a loop and examine all circ to draw circles on the screen.

I wrote the code using Hough function its very helpful

Hi, just a question, this is an OpenCV sample program or you wrote the code?

Is there a way to know what opencv funtions did you use it?

Thanks.
