Reconstruction of Arabic Font with Quartic Bezier Curve

Curve fitting is one of the main problems in reverse engineering which is immensely worked on during the last two decades. In this paper, a new technique and an algorithm have been designed to capture the outlines of Arabic fonts. Differential evolution (DE) had been used to find the optimal solution of the curve fitting problem by using quartic Bezier curve. The process of capturing outlines includes the following steps: Boundary extraction and corner point's detection, chord length parameterization and curve fitting. In order to ensure that the control point that was chosen is the best in result, the parametric curve such that it is approximate to the original curve; sum square error (SSE) was used to calculate the distance between boundary of the original image and the parametric curve.
