Abstract : This report describes the mathematical processes involved in generating co-efficients from a binary image of an object. It includes fourier descriptor theory, the normalized fourier descriptor, description of system implementation with library generation, chain code format, normalized fourier descriptor calculation, feature vector format, feature reduction, unknown feature vector extraction, feature vector classification and results applied to target recognition.
