Connelly Barnes will present his research seminar/general exam on Tuesday 
May 6 at 3PM in Room 402.  The members of his committee are:  Adam 
Finkelstein (advisor), Szymon Rusinkiewicz, and Perry Cook.  Everyone is 
invited to attend his talk and those faculty wishing to remain for the oral exam 
following are welcome to do so.  His abstract and reading list follow below.


We present a video-based interface that allows users of all skill
levels to quickly create cutout-style animations by performing the
character motions. The puppeteer first creates a cast of physical
puppets using paper, markers and scissors. He then physically
moves these puppets to tell a story. Using an inexpensive overhead
camera our system tracks the motions of the puppets and renders
them on a new background while removing the puppeteer's
hands. Our system runs in real-time (at 30 fps) so that the puppeteer
and the audience can immediately see the animation that
is created. Moreover, our system supports a variety of constraints
and effects including articulated characters, multi-track animation,
scene changes, camera controls, 2.5D environments, shadows, and
animations cycles. We demonstrate that even first-time users, including
an eleven-year-old, can use our system to quickly turn a
story idea into an animation.
