摘要：
A method to detect five parameters of an ellipse with an optical Hough transform is described. The method employs the Hough transform for detection of a straight line and for the one-dimensional analysis of the resultant parameter domain. This technique is also applied for detection of four parameters of a straight line segment (the two coordinates of the center, the length, and the orientation) by representing it as a particular case of an ellipse with one axis of zero length.
