SUMMARY:Vision-based sensing of human activities and reflectance analysis 
 - Yoichi Sato\, University of Tokyo
DTSTART:20070517T131500Z

CONTACT:Tom Cashman
DESCRIPTION:In this talk\, I am going to give a brief overview of our rese
 arch projects at the University of Tokyo\, focusing on two research topics
 . The first part of my talk will cover vision-based sensing and understand
 ing of human activities. Sensing various kinds of human activities in real
 -time is a key component of human-machine interactions. We have been worki
 ng on vision-based techniques for sensing human body motions at different 
 levels of details: 3D tracking of people in complex scenes\, estimation of
  facial pose and deformation\, and gaze estimation from low resolution ima
 ges. I will explain each of the techniques as well as some results from ou
 r on-going attempts to apply our techniques for human activity analysis. T
 he second part of this talk will cover our recent project on photometric c
 ompensation of projector-camera systems to compensate irregularities in th
 e output of digital projectors that occur when they are used in non-ideal 
 situations\, such as those with varying surface reflectance and ambient li
 ght.
