Shape description by UNL Fourier features-an application to handwritten character recognition

Handwritten characters are forms. Thus they are accessible to form description methods. The authors present a universal shape characterization method applied to the domain of off-line handwritten characters. The test universe is restricted to the ten Arabic numerals but can be extended to any other characters. The authors point out previous work in the area of 2D shape classification and handwriting recognition. The theoretical concept of the authors´ shape descriptor is introduced together with a recipe to apply it in the real case of discrete binary images. Results of classification experiments are presented
