Summary

Two fundamental techniques of fonts representation are bitmap and outline. The outline fonts are produced from a gray-level image obtained by scanning the original characters drawn on paper. Contour points are obtained from the gray-level image and significant points are determined from contour points. Splines are approximated/interpolated to these significant points. In traditional font design systems, the user specifies significant points by some interactive device (e.g. mouse. The system then generates a curve whose shape depends on specified points and mathematical model of the curve. There are several drawbacks of this method. The user has to be familiar with the underlying mathematical model of the system in order to use it properly. Human intervention and changing set of points many tunes makes this method slow. Accuracy up to desired tolerance limit is difficult to achieve. We proposed an efficient font design method that automate the process of font design by finding minimal number of significant points, removing noise from contour, fitting cubic Bezier to significant points and Optimizing the closeness of fit between original digitized curve and our parametric curve.
