Abstract
A method and system of line extraction in a digital ink sequence of handwritten text data points is provided in which a stroke sequence comprised of a sequence of strokes is obtained, the strokes are segmented into a sequence of substrokes by applying a stroke segmentation algorithm, angular differences between neighboring groups of substrokes, in the sequence of substrokes, are calculated, and the positions of the extrema of the angular differences are determined, thereby identifying the substrokes at line breaks and enabling line extraction.
