[4eyes] Visual Computing Cafe Seminar Friday Sept 27, 2013

[Pradeep Sen]

Hi everyone,

We are kicking off a new seminar series for the
UCSB Center for Visual Computing this Fall.

This bi-weekly seminar series will feature topics
related to visual computing, spanning areas such as
computer vision, computer graphics, image processing,
augmented/virtual reality, imaging, visualization,
and human-computer interaction.

The speakers will be researchers in visual computing
from both UCSB and the outside community.  Hope to
see you there!

PS. In the future to avoid double spamming the 4-Eyes
     list, I will only post this to the CVC mailing list,
     so please sign up if you haven't already:

TITLE:
Principles and Observation: How do people move?
by Jehee Lee, Seoul National University/Disney Research


ABSTRACT:
The animation and simulation of human behavior is an important
issue in the context of computer animation, games, robotics, and
virtual environments.  The study on human movements and animal
locomotion has revealed various principles based on physics,
biomechanics, physiology, and psychology.  Many of existing animation
techniques rely on those principles, which may be described as a
form of mathematical equations, sets of rules, procedures, or
algorithms.  Another stream of research, called data-driven animation,
made use of human motion data captured from live actors. The research on
data-driven animation has developed a variety of techniques to edit,
manipulate, segment and splice motion capture clips. In this talk, we
argue that these two approaches are complementary to each other.

Over the past few years, we have explored several methods that
addressed the problem of simulating human behaviors in virtual
environments. Each solution relies on different principles of human
movements and motion data captured at different scales. We found that
principles and observed data can interact with each other in several
ways. Sometimes, motion data drive physically-simulated bipeds to
walk, turn, and spin. Physics principles guide interactive motion
editing to make a canned jump higher/wider and a spin longer. Some
principles can be learned from observed data to understand how
people move in complex environments, what regularities human motion
tends to exhibit, and how pedestrians behave in crowds. Understanding
the interaction between principles and observed data would be a key
aspect of character animation research.


BIO:
Jehee Lee is a professor in the Department of Computer Science and
Engineering at Seoul National University and currently with Disney
Research at Los Angeles as a visiting research scientist. His research
is in the area of computer graphics. He is particularly interested in
developing new ways of understanding, representing, and animating human
movements. This involves full-body motion analysis and synthesis, motion
capture, motion planning, interactive avatar control, and intelligent
synthetic characters. He is leading the Movement Research Lab.
