Abstract

In this paper, a novel ellipse extraction method based on edge segments formed by edge detection in an image is proposed. Edge segments are split into small pieces based on polygonal approximation and adjacent pieces are merged to elliptical arc segments according to the defined constrain. Then arc segments belong to the same ellipse are grouped into one arc segment by improved RANSAC algorithm. Finally, the accurate ellipse parameters are obtained by the least square fitting with those edge points lying on the same grouped arc segment. Experiments on synthetic and real images verify the good performance of the proposed method in the complex background images.
