Handwritten Arabic Digits Recognition Using Bezier Curves
In this paper we propose a new recognition approach for Arabic numerals. Given that the performance of recognition systems for Arabic numerals are closely linked to the choice of features and classification system used in the recognition phase, we seek to exploit the possibilities of the theory of Bzier curves that allows representing parametric curves from a limited number of data (some characteristic dots with their derivatives). Indeed, the characteristic dots of the Arabic digit that we have adopted are those such that their associated Bezier curve is close to the shape of the digit. The used classifier in this work is the k-nearest neighbour. The obtained results testify to the interest and the strength of our approach.
