Visual barcodes that serve as fiducial targets with variable resolution. We call them Fourier tags.
With Dimitri Marinakis I have been looking at inferring the topology of sensor networks using very sparse event information.
A preliminary paper on our recommender system work (visit recommendz to try it and get a movie recommendation).
Work that compares PCA to landmark-based posed estimation schemes, with Rob Sim: Comparing image-based localization methods (IJCAI 2003).
Work on using visual landmarks for pose estimation. We have look at several variants of this and the following CVPR 2001 paper (postscript, gz) uses generative models.
Initial work on reconstruction of depth images from intensity data with Luz-Abril Torres Mendez, from the proc. IEEE Workshop of Applications of Computer Vision 2002 (PDF file). (Starting paper, see newer papers for better results.)
With Yiannis Rekleitis and Evangelos Milios, we have been looked at using multiple robots to reduce errors during mapping. This paper is Multi-Robot Collaboration for Robust Exploration (this link is for a PDF reprint from the Annals of Mathematics and Artificial Intelligence, 2001).
An ICCV 1999 paper on learning landmarks for pose estimation (gzipped postscript).
A Taxonomy for Multi-Agent Robotics. Combines a taxonomy, some new results, and a survey of existing work. A preprint of this article can be found as a PDF file (an older journal article that was retreaded and updated for the book Robot Teams: From Diversity to Polymorphism, T. Balch and L. E. Parker (Eds.), 2002).
Global localization: Localizing a Robot with Minimum Travel, with Kathleen Romanik and Sue Whitesides, SIAM J. Comput, 27, 2, April 1998, pp. 583-604. (300 KB).
Localization from sonar models, with Paul MacKenzie, compressed postscript.
Just-in-time sensing from sonar and laser data, ICRA 1996. with Rekleitis and Freedman.
Work on the classification and use of sonar landmarks, with Simon Lacroix who did a postdoc at McGill, IROS 1997 (postscript).
Computing ``shape texture'' for recognition (compressed postscript).
2-D shape-from-darkness and how hidden surfaces can be recovered. Langer, Dudek, Zucker, IROS 1995 (postcript).
Multi-robot exploration, with Rekleitis and Milios, ICRA 1996 (compressed postscript).
3-D shape-from-darkness using iterative ``carving'' and arbitrary light source directions. Daum and Dudek, CVPR 1998.

The AQUA underwater walking robot project. ( AQUA mirror.)
Try our movie recommendation system. To use it, rate a few movies that you like and dislike, and we'll try and provide some additional suggestions to you. It uses some interesting new ideas we're developing.
Help the orangutan.
A nice book on robot teams.
List of science gift suggestions.
Robot and science wear; cool in that they feature our robotics book cover.
Techie paraphenalia.
Robotics in the New York Times. Kind of old, but still accurate.
Reading this New York Times article might require a (free) registration. (Knight Ridder Syndicated, April 1999.) ).
The McGill "Martian Explorer": our winning entry in the 1997 & 1998 AAAI Mobile Robotics Competition.
Friends who offer consulting services.
A citation search engine, exemplified using a search for citations to my publications citations to some of my publications.
