Abstract
The invention provides a computer-implementable method for detecting substroke boundaries in handwriting input. The method selects pen tip velocity extremas to represent. substroke boundaries. The method includes steps for generating a velocity profile from the handwriting input; identifying a plurality of peak extrema within the velocity profile; identifying a plurality of in-line extrema within the velocity profile; and detecting the substroke boundaries by filtering the plurality of peak extrema and the plurality of in-line extrema.
