Paper Abstract

By extracting the basic features of an object shape from a digitized Fourier transform image, one can calculate its scale factor and orientation angle. Because of the accuracy of the computed scale and orientation parameters, this formulation can be extended to object classification applications. The concept and system implementation of such a pattern recognition system based on a look-up table interpolation technique for arbitrary-shaped objects are discussed. Finally, the results of performance analysis are presented.
