TITLE:
Smart Projectors: Computer Vision for Projected Displays

ABSTRACT:
We present methods for enhancing projected displays using computer vision. Visual feedback in camera-projector systems enables us to solve problems that are traditionally difficult in passive camera settings. This talk focuses on three issues: geometric alignment, photometric correction and user interfaces for projected displays. We illustrate our ideas with three practical systems: (1) a self-calibrating presentation system that allows users to place the projector anywhere in the room and control the presentation using a laser pointer or handheld computer; (2) a display that uses redundant lighting from several micro-portable projectors to dynamically eliminate shadows cast by the user; (3) an algorithm for automatically aligning tiled multi-projector displays walls of arbitrary size.

BIO:
Rahul Sukthankar is a senior researcher at HP Labs Cambridge Research Lab (formerly Compaq/DEC CRL) and also holds a courtesy appointment as adjunct faculty (Robotics) in the School of Computer Science at Carnegie Mellon. He was previously a research scientist at Just Research for three years. Rahul received his Ph.D. at CMU in 1997, and his B.S.E. summa cum laude in computer science at Princeton in 1991. His current research focuses on computer vision and machine learning, particularly in the areas of face recognition and innovative user interfaces.
