Notes from DAS2006
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 (Loria)
- Jim Fruchterman (Benetech)
- Koichi Kise (Osaka Prefecture University)
- Bertin Klein (DFKI)
- Marcus Liwicki (University of Bern)
- Larry Spitz (DocRec Ltd)
- Noorazrin Zakaria (Université de la Rochelle)
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.
