Abstract
In this paper, a given handwritten curve will be approximately converted into a B้zier curve. First, a number of sampled points on the given curve are systematically chosen to guarantee that the B้zier curve can be adequately modeled without the loss of curve characteristics. These points are considered to be the B้zier control points. The Progressive-Iterative Approximation (PIA) is then adopted to construct the interpolating curve. Employing PIA algorithm, Bernstein polynomials are selected to be a blending function of PIA so that this interpolating curve will develop a B้zier curve. This technique will avoid the ill-conditioned circumstance because of using Newton/Lagrange polynomials in curve fitting. ฉ 2013 IEEE.
