ABSTRACT:
A handwriting input method and apparatus is disclosed which generates a single line segment from a group of input line segments which are input by a user. The input line segments may be overlapping or disconnected short line segments, thereby allowing the user to enter lines in a free stroke format, much the way an artist sketches. For each of the input line segments a plurality of variable parameters are detected from the stroke data. The parameters for each input line segment are converted to a three-dimensional weighting function. The weighting functions for different line segments are combined, the edge of the resulting combined function is detected, and that edge is displayed as a line segment on a display device.
