ABSTRACT:
A system and method receives a set of data points and identifies one or more Bezier curves corresponding to the set of data points. The system and method uses different techniques for identifying the Bezier curve depending on whether a Bezier point is a sharp point, in which the slope of the lines on either side of the point differ by a threshold amount or another type of point.
