Grouping writing regions of digital ink

摘要

A method for grouping writing regions of digital ink receives processed digital ink that comprises writing regions. A relationship can be generated between a plurality of the writing regions. A feature set can be determined that is associated with the plurality of the writing regions. The plurality of the writing regions can be grouped based on the feature set.

主权项

1. A system, comprising:
one or more processors; and memory comprising instructions that when executed by at least one of the one or more processors perform a method for grouping writing regions of digital ink, the method comprising:
applying a prune-and-clone technique to digital ink to generate pruned digital ink by deep-copying at least a first structure and leaving at least a second structure as a shadow, wherein deep-copying the first structure includes copying ink stroke data of the first structure, wherein leaving the second structure as a shadow includes avoiding copying ink stroke data of the second structure, and wherein applying the prune-and-clone technique sets an upper-bound on an amount of structures entering a parser of digital ink by excluding shadowed structures from entering the parser;determining a first writing region of the pruned digital ink and a second writing region of the pruned digital ink; anddetermining whether to group the first writing region with the second writing region.
