Abstract
The document browser for electronic filing systems supports pen-based markup and annotation. The user may electronically write notes anywhere on a page and then later search for those notes using the approximate ink matching (AIM) technique. The technique segments the user-drawn strokes, extracts and vector quantizes features contained in those strokes. An edit distance comparison technique is used to query the database, rendering the system capable of performing approximate or partial matches to achieve fuzzy search capability.
