ABSTRACT:
The method and microprocessor of the present invention includes a step of calculating the angle changes, in the handwritten input. The method then selects potential segmentation points in the input whose angle change exceeds a predetermined threshold. The segmentation points are used to determine a sequence of straight line strokes that may be used by a recognizer for interpretation of the handwritten input.
