This paper develops a recursive method for computing moments of 2D objects described by elliptic Fourier descriptors (EFD). Green's theorem is utilized to transform 2D surfac...
This paper describes tools for character string recognition on maps. Single character recognition is performed using elliptical Fourier descriptors applying a statistical classi er...
Shape representation provides fundamental features for many applications in computer vision and it is known to be important cues for human vision. This paper presents an experiment...

This paper deals with the performance evaluation of three object invariant descriptors : Hu moments, Zernike moments and Fourier-Mellin descriptors. Experiments are conducted on a...
Various types of moments have been used to recognize image patterns in a number of applications. However, only few works have paid attention to the completeness property of the in...
