Hi,
I recently tried a circular/ellipse detection using OpenCV fitellipse and NI's shape(circular/ellipse) Detection using an incomplete circle image.I found
1. NI's results much better than OpenCV.
2. Find Circular Edge get a little different result with shape(circular/ellipse) Detection.(Circular and ellipse detection in Shape Detection obtained the same result.)
I wander what is the algorithm behind the 'find circular edge1' and circles/ellipses of 'shape detection 1'. If you can show me the link or the clue I would be great appreciated.
