Abstract

In this paper the ellipse-specific contour grouping algorithm is introduced. It is a technique for detecting elliptical shapes from images. The algorithm uses ellipse-specific direct least square fitting and elliptic variance descriptor to assess an error of fit. A survey of other methods for detecting elliptical shapes is performed. Contour grouping techniques are discussed in details. The algorithm was illustrated on real images obtained from cytological phase contrast microscopy.
