摘要： A system is provided having a database storing annotation digital ink representing handwritten annotations on a printed document and a processor configured to segment the annotation digital ink into lines by obtaining a stroke sequence comprised of a sequence of strokes, removing small strokes less than a threshold length, segmenting the strokes into a sequence of substrokes by computing a relative angle for each line segment connecting successive stroke data points and segmenting the stroke into substrokes if the difference between successive relative angles is greater than a preset threshold, and identifying the substrokes at line breaks, thereby facilitating line extraction, by computing N-neighbourhood centroids, computing angular differences between N-neighbouring substrokes, or groups of substrokes and computing local maxima of the angular differences in the sequence of substrokes.
