1. A computer-implemented method for classifying digital ink, said method comprising:
- receiving digital ink comprising ink strokes;
classifying a plurality of said ink strokes;
performing a temporal line grouping on a plurality of said classified ink strokes to form a temporal line group;
segmenting said temporal line group into a cluster; and
classifying said cluster, at least some of at least one of the receiving, the classifying, the performing, the segmenting, and the classifying said cluster implemented at least in part via a microprocessor.

Abstract
A method for classifying digital ink receives digital ink comprising ink strokes. A plurality of the ink strokes can be classified. A temporal line grouping is performed on a plurality of the classified ink strokes that are grouped to form a temporal line group. The temporal line group is segmented into a cluster. The cluster can be classified.

15. A system for classifying digital ink, said system comprising:
-
a stroke classification module configured for receiving digital ink comprising ink strokes, said stroke classification module configured for classifying a plurality of said ink strokes as a writing or as a drawing; a temporal line grouping module coupled with said stroke classification module, said temporal line grouping module configured for receiving any ink strokes classified as said writing by said stroke classification module, said temporal line grouping module configured for performing a temporal line grouping on said any ink strokes and for producing a line group; and a line-level classification module coupled to receive said line group and configured for segmenting said line group into a plurality of clusters, said line-level classification module configured for classifying a cluster of said plurality of clusters as a writing or a drawing, at least some of at least one of the stroke classification module, the temporal line grouping module, and the line-level classification module implemented at least in part via a microprocessor. - View Dependent Claims (16, 17, 18, 19, 20)
