Extraction of partially occluded elliptical objects by modified randomized hough transform

초록

Ellipse detection is very important in computer vision, object recognition, feature selection and so on. This paper proposes a new ellipse detection method using local information of edge points. It merges line segments using modified randomized Hough transform (RHT) that belongs to same ellipse. It is fast, correct and robust to noise because it detects ellipse using line segments that are constructed by local information of edge points. The proposed method in Ulis paper can not apply only ellipse detection but line, circle and partially occluded elliptical object. © Springer-Verlag Berlin Heidelberg 2007.
