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.
