From: ahmad yahya on 29 Jan 2010 04:20 i want to find the major and minor radius in ellipse,to image and i do not know exactly the point, p1(x1,y1),p2(x2,y2),p3(x3,y3),p4(x4,y4) how can calculate this point
From: ImageAnalyst on 29 Jan 2010 06:22 ahmad yahya: Didn't they already answer this yesterday? You need 5 points to define an ellipse. If you don't know the 5th point, you can't do much - there are lots of ellipses that can go through only 4 points.
