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.
