Corey Toler-Franklin will present her research seminar/general exam on Monday
May 21 at 2PM in Room 402. The members of her committee are: Szymon
Rusinkiewicz (advisor), Adam Finkelstein, and Tom Funkhouser. Everyone is
invited to attend her talk, and those faculty wishing to remain for the oral exam
following are welcome to do so. Her abstract and reading list follow below.

Illustration of Complex Real-World Objects using Images with Normals
Corey Toler-Franklin
This project investigates the creation of non-photorealistic illustrations from a type of
data lying between simple 2D images and full 3D models:
images with both a color (albedo) and a surface normal stored at each pixel. Images with
normals combine an acquisition process only mildly more complex than that for digital
photographs (and significantly easier than 3D scanning) with the power and flexibility of
tools similar to those originally developed for full 3D models. We investigate methods
for signal processing on images with normals, developing algorithms for scale-space
analysis, and segmentation. These are used to implement analogues of stylized rendering
techniques including toon shading, line drawing and and exaggerated shading. We believe
that images with normals or "RGBN images" may become an important and widely-used data
type, because of the ease, flexibility, and quality with which they may be acquired, and
because they contain enough information to permit sophisticated analysis and depiction.We
show that our rendering pipeline can produce detailed yet understandable illustrations in
medical, technical, and archaeological domains.
