Making Effective Artistic Renderings
Tuesday, November 02, 2004, 01:00pm - 02:00pm
Rutgers University, Computer Science and Cognitive Science
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.
