Partial shape matching using convex hull and Fourier descriptors

Krzysztof Kocjan

Abstract


An application of Fourier descriptors and convex hull for shape analysis is presented. Convex hull is used for dividing a shape into small parts. Amplitude spectrum which is invariant to scaling, translation and choosing a starting point is obtained from the Fourier descriptors (see e.g [1-3]) and used for comparison. All calculations are performed with the author's software and some algorithms from literature [1,4]. For convex hull estimation the Graham algorithm is used.
