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.
