这是一篇关于椭圆检测的文章:对于做人脸识别,模式识别的同行应该会有所帮助.找了好久,才下到,上传来共享下.-abstract:The Hough transformation can detect straight lines in an edge-enhanced picture, however its extension torecover ellipses

requires too long a computing time. This correspondence proposes a

modified method which utilizes two properties of an ellipse in such a

way that it iteratively searches for clusters in two different parameter

spaces to find almost complete ellipses, then evaluates their parameters

by the least mean squares method.
