I just got back today from the 7th IAPR International Workshop on Document Analysis Systems (proceedings), held in Nelson from 13-15 Feb.

The presentations were all about document or image analysis, but the heavy use of AI techniques could make some of it relevant to what I work on these days.

Some of the interesting people I met or caught up with:

• Adam Behringer (Exbiblio)
• Abdel Belaid
• Jim Fruchterman (Benetech)
• Koichi Kise (Osaka Prefecture University)
• Bertin Klein (DFKI)
• Marcus Liwicki (University of Bern)
• Larry Spitz (DocRec Ltd)
• Noorazrin Zakaria

Projects I should take a look at:

• GroupLens (recommendation system)
• Semantic Wikis (workshop)
• PRImA Research document database
• OpenCV
• Digital Library of India
• IUPR camera-captured document archive
• Tohoku University's OCR web service
• IAM-OnDB pen-captured writing database

Techniques I should learn (or re-learn):

• Gabor filters
• Hidden Markov models
• Standard classifiers: NNC, LDC
• Analytical segmentation
• Dynamic programming
• Viterbi algorithm
• Dynamic time warping
• RAST algorithm for alignment
• X-tree spatial indexing algorithm
• Affine invariants
• Gaussian mixed models

Things that should exist:

• A better browser for mailing lists - that thinks more about the message content and tries to figure out what's going on, presenting more statistics etc in the list view to help you find interesting messages.
• A browser for academic papers with tagging so you can collect together papers on a very specific subject without prejudicing the normal categorisation.
• Realtime image stitching - build a panorama out of a video. (Existing: traffic monitoring.)
• Connected component analysis on colour images.
