Abstract

In this paper, we propose a joint elliptical arc, circular arc, and line segment detector based on the a contrario statistical approach. Our method is an extension of the ELSDc method, recently proposed for line segment and elliptical arc detection. The main contribution is a more general geometrical model, which allows the joint evaluation of the best combination of elliptical arcs, circular arcs, and line segments that corresponds to a given contour. Different interpretations in terms of these elements are tried for the whole contour, instead of locally as it is done in ELSDc. In addition, several minor improvements were performed to the heuristic algorithm used to propose candidates. The performance of the proposed method is compared to the original one on synthetic and real images.
