Abstract
A handwritten character recognition system that includes a document scanner for generating scanned images of a previously created document containing handwritten characters, and a pen and digitizing tablet for real time entry of handwritten characters by a user. The handwritten character recognition system includes an image processor connected from the document scanner for receiving the scanned image of a previously created document and generating one or more ordered cluster arrays. The ordered cluster arrays contain spatially ordered coordinate arrays of skeletal image arcs representing and corresponding to the strokes of the handwritten characters wherein the spatial order represents an induced time ordered sequence of creation of the strokes of the handwritten characters that emulates the sequence of creation of the character strokes. A low level recognition processor is connected from the time order induction processor for receiving the ordered cluster arrays and generating a sequential character array wherein the sequential character array contains a character list for each ordered cluster array and wherein each character list contains at least one character identification representing a possible interpretation of the corresponding ordered cluster array. A linguistic post processor may be connected from the low level recognition processor for receiving the sequential character array and generating an output string representing the most probable interpretation of the handwritten characters of the document.
