An Amazing Paper on Vision-based Methods

Just found an amazing paper that deserves its own blog post. It's a huge survey of vision-based mobile robot navigation methods written by Kak and DeSouza in 2002. The goal, as stated by the authors, was to write about vision-based techniques from "the last 20 years". The article contains more than 150 references, and can be found here: http://portal.acm.org/citation.cfm?id=505501.505509.

I should upload the BiBTeX database again, as it contains some more new references.
