What and Who

Modeling and representing materials in the wild

Kavita Bala
Cornell University
SWS Distinguished Lecture Series

Kavita Bala is an Associate Professor in the Computer Science Department at
Cornell University. She received her PhD from the Massachusetts Institute of
Technology (MIT). Bala leads research projects in physically-based scalable
rendering, perceptually-based graphics, material perception and acquisition,
and image-based modeling and texturing. Her group's scalable rendering
research on Lightcuts is the core rendering technology in Autodesk's cloud
rendering platform.
Bala's professional activities include Chair of SIGGRAPH Asia 2011, co-Chair
Pacific Graphics (2010) and the Eurographics Symposium on Rendering (2005),
Papers Advisory Board for SIGGRAPH and SIGGRAPH Asia, Senior Associate Editor
for TOG, and Associate Editor for TVCG and CGF. She has received the NSF
CAREER award, and Cornell's College of Engineering James and Mary Tien
Excellence in Teaching Award (2006 and 2009)

Our everyday life brings us in contact with a rich range of materials that
contribute to both the utility and aesthetics of our environment. Human beings
are very good at using subtle distinctions in appearance to distinguish between
materials (e.g., silk vs. cotton, laminate vs. granite). In my group we are
working on understanding how we perceive materials to drive better graphics and
vision algorithms.

In this talk I will present OpenSurfaces, a rich, labeled database consisting
of thousands of examples of surfaces segmented from consumer photographs of
interiors, and annotated with material parameters, texture information, and
contextual information. We demonstrate the use of this database in applications
like surface retexturing, intrinsic image decomposition, intelligent
material-based image browsing, and material design. I will also briefly
describe our work on light scattering for translucent materials and realistic
micron-resolution models for fabrics. Our work has applications in many
domains: in virtual and augmented reality fueled by the advent of devices like
Google Glass, in virtual prototyping for industrial design, in ecommerce and
retail, in textile design and prototyping, in interior design and remodeling,
and in games and movies.
