Test and Measure of Circularity for Digital Curves

Abstract

We propose one geometric algorithm to solve both the problem of circularity test and the problem of circularity measure. The former problem consists in deciding whether a given digital curve is a digitization of a circle or not, whereas the latter problem consists in measuring how far a given digital curve is from a digitization of a circle. Our new circularity measure fulfills basic invariance properties and equals 0 for all digital circles and is positive for all shapes that are not digital circles. Experiments performed on synthetic and real images are very good.
