Abstract :
Capturing outlines is a useful method for shape compression and digitization for computer storage and for subsequent computational efficiency. This work presents an optimal cubic Bezier curve design, which is particularly useful for capturing outlines of 2D shapes including hand-drawn shapes and fonts. The methodology, discussed in this paper differs from traditional approaches in that, it is not aimed to find characteristic points, which are interpolated to get approximated curve. The proposed method is used to find suitable location of control points for any curve such that a simple Bezier curve generated over these control points approximates the original curve.
