Title: Effective Artistic Renderings

Abstract: I will describe two ongoing projects that seek to produce
easily-perceived imagery using new theories in cognitive science that relate
artistic images to realistic images through our understanding of human visual
perception. Much of this talk will focus on a new computational approach for
making convincing line-drawings of three-dimensional shapes. It goes beyond
occluding contours (which include the silhouette) and creases, and relies
on a new class of lines: suggestive contours. Suggestive contours are lines on
the surface that become true contours in nearby viewpoints; they turn out to be
located at certain view-dependent inflections of the surface. Suggestive contours
convey much richer information about shape than contours can alone, yet they do
so in a way that harmonizes with the contours. Supported by a range of examples,
I'll discuss the mathematical properties of suggestive contours, their perceptual
implications, and their computational realization.

Biographical Sketch: Doug DeCarlo received BS degrees in computer science
and computer engineering from Carnegie Mellon in 1991, and his PhD in
computer science from the University of Pennsylvania in 1998. He is
currently an assistant professor in the Department of Computer Science
with a joint appointment in the Center for Cognitive Science at Rutgers
University. His research in computer graphics explores how accounts of
human perception and communication can inform the design of computer
systems that engage in effective visual communication.
