Computer Science Professor Aditi Majumder and graduate student Behzad Sajadi have received the Best Paper Award at the IEEE Virtual Reality 2010 conference held in Boston.
The paper, entitled "Auto-Calibration of Cylindrical Multi-Projector Systems," explores registering multiple projectors on vertically extruded a cylindrical display, which previously was only possible with a calibrated stereo camera.
This papers shows that using some simple priors, one can achieve multiple projector registration on a cylindrical display using a single uncalibrated camera without any markers on the display. More importantly, the new method enables use of multiple overlapped projectors across corners of a vertically extruded surface with sharp edges. This is of tremendous benefit to virtual reality display systems like CAVEs, that avoided mounting projectors across the corners until today.

IEEE Virtual Reality 2010 is the top international venue for virtual reality researchers and practitioners.
Professor Majumder's research addresses how to produce a seamless image on a large-scale tiled display - an important problem to both the scientific and entertainment fields. Majumder has developed a suite of mathematical models, methods and software to correct the geometric, chromatic and luminescent variations that arise when tiling multiple projection displays.
