Detection of Ellipses by a Modified Hough Transformation
August 1978 (vol. 27 no. 8)
pp. 777-781
S. Tsuji, Department of Electrical Engineering, Faculty of Engineering Science
The Hough transformation can detect straight lines in an edge-enhanced picture, however its extension to recover 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.
