Cursive Character Recognition System

Abstract

During the last two decade, numerous handwriting character recognition systems have been proposed. Many of them presented their limitation when the handwriting character is cursive type and it has some deformation. However this type of cursive character is easily recognized by the human being. In this paper we research its human ability and apply it to the dynamic handwriting character recognition. In the proposed system, significant knots of each character are extracted using natural spline function named SLALOM and their position is optimized steepest descent method. Using a training set consisting of the sequence of optimal knots, each character model is constructed. Finally the unknown input character is compared with each model of all characters to get the similarity scores. The character model with higher similarity score is considered as the recognized character of the input data. The recognition stage consists in two-steps: classification using global feature and classification using local feature
