A METHOD FOR MODELING FREEHAND CURVES - THE FUZZY SPLINE INTERPOLATION

In this paper, a fuzzy spline interpolation technique is proposed to g ive a fuzzy model of sampled freehand curves that involve vagueness (a ssociated with roughness is drawing) in their positional information. The fuzzy model is an extension of ordinary spline curves. Because the model inherits geometric characteristics from spline curves and can b e handled as a fuzzy set, it provides a fuzzy inference approach to th e geometric meaning of the drawer's original intention, allowing for t he vagueness of the drawn freehand curves. An application of the model to freehand curve segmentation demonstrates the necessity of the meth od.
