Abstract:
A television weatherforecaster appears with a satellite map but is 
really standing in front of a blue screen. \emph{Matting} is the process 
of separating the forecaster from the screen; doing this if the 
forecaster is instead in front of a complex moving background, say 
traffic in New York City, is an open problem.  I present a solution to 
this problem as one instance of what can be accomplished with a camera 
containing multiple video sensors.

Most cameras contain a single sensor that measures, at each pixel, the 
amount of light near specific red, green, and blue wavelengths.  Using 
multiple sensors we can measure more wavelengths, multiple exposures, 
different polarizations; we can even consider different lens parameters. 
  Future cameras will likely have these capabilities, which raises 
interesting questions:

* What are good designs for multi-sensor cameras?
* How can we use them to solve current problems?
* Given multiple sensors, what new applications can we explore?

In this talk, I present a general framework for working with 
multi-sensor cameras, demonstrate several applications, and describe 
methods for construction, calibration, and optimizing optical design.
