Abstract:
1. A method of recognizing shapes from a scribble, the method comprising the steps of: a. identifying one or more important points in a scribble; b. determining whether said scribble resembles a closed figure; c. determining whether said scribble resembles a figure with more straight sides than curved sides; d. recognizing said scribble as a line segment if said scribble has exactly two important points; e. recognizing said scribble as a piecewise linear curve if said scribble has more than two important points and said scribble has more straight sides than curved sides and said scribble is not a closed figure; f. recognizing said scribble as a spline if said scribble has more than two important points and said scribble does not have more straight sides than curved sides and said scribble is not a closed figure; g. recognizing said scribble as a closed plane figure if said scribble has more than two important points and said scribble has more straight sides than curved sides and said scribble is a closed figure; h. recognizing said scribble as a closed spline if said scribble has more than two important points and said scribble does not have more straight sides than curved sides and said scribble is a closed figure.
