In pattern recognition, detection of partial ellipse is important, because a circlar object usually looks as ellipse unless seeing the object on its vertical center line, and it often becomes partial ellipse when it is hidden by some foreground object. However an efficient detection algorithm for a partial ellipse is scarcely reported except approximation by the least mean squares method. This paper described a newly developed detection algorithm for partial ellipse and some results of evaluation experiments.
