opencv轮廓检测之椭圆检测-----算法篇(11)--fitEllipse算法解释

当然, 想看历届的会议http://www.bmva.org/bmvc/

www.bmva.org/bmvc/1995/bmvc-95-050.pdf   A Buyer's Guide to Conic Fitting

opencv文档上说,  拟合椭圆用的是least square 方法

而[Fitzgibbon95]讲了五种least square的算法并对比椭圆拟合实验效果

至于用了哪一种, 文档上没有具体说明,  可能需要看源码了

不如就看看这篇引用超过两千次的文章

Direct Least Squares Fitting of Ellipses
