PROJECT TITLE :

Effective ellipse detector with polygonal curve and likelihood ratio test

ABSTRACT:

A robust ellipse detector is proposed. The detector preprocesses the sting map by removing all the isolated points and conjunction points, and exploits polygonal curve to extract the elliptical arcs. A non-iterative geometric distance computation method is presented to serve a criterion that identifies the elliptical arcs belonging to the same ellipse by probability ratio test and work ellipses to those merged arcs. The authors take a look at their algorithm on both synthetic and real images, and also the experimental results show a sensible performance of their algorithm.
