Collaborative Observatories for Natural Environments: Searching for the Ivory Billed Woodpecker and other Elusive Creatures May 11, 2007 You need Flash player 8+ and JavaScript enabled to view this video.
I'll describe a new class of systems that combine networks, robots, cameras, sensors, actuators, and human input to observe and record detailed animal behavior in remote settings. In one application, we are assisting the Cornell team that is searching a remote area of Arkansas for the elusive Ivory Billed Woodpecker, thought extinct since the 1940s. I'll present a series of results on robots collaboratively controlled by humans via networks. My lab has been investigating the algorithmic foundations for such observatories: new metrics, models, data structures, and algorithms, that will comprise a robust, mathematical framework for collaborative observation. Newly available robotic cameras offer pan, tilt, and extreme zoom capabilities with built-in network servers at low cost. These cameras motivate the Single Frame Selection (SFS) problem, where $n$ users share control of a single robotic camera. I'll present several algorithms, O(n^2 m) for a set of m zoom levels, and O((n + 1/\epsilon^3) log^2 n) for an infinite set of zoom levels. The algorithms can be distributed to run in O(n m) time at each client and in O(n \log n) time at the server. We are building prototypes that will be accessible via the internet to scientists, students, and the public worldwide. http://www.c-o-n-e.org/ This work is joint with Prof. Dez Song at Texas A&M and supported in part by the National Science Foundation. |
