Computation is the New Optics:
Coded Imaging in Computational Photography
The principle of image formation had so far remained largely unchanged since the invention of photography: a lens focuses light rays from the scene onto a two-dimensional sensor that records this information directly into a picture. The final image is a simple copy of the optical image reaching the sensor and image quality enhancement is usually obtained through improvement in the optics. The emerging field of computational photography challenges this view and proposes to leverage computation between the optical images and the final picture to alleviate physical limitation, enable flexible post-capture editing, record new types of information such as depth, and enable novel visual experience.
The addition of computation means that the optical image does not need to be similar to the final image, which greatly expands the possible imaging strategies. Computation can be more than a simple post-processing that takes as input a traditionally-formed image, it also deeply changes the rules of the game for the optical side of imaging. New optics must be designed together with the computation to optimize the whole imaging process. Until now, optics has been the key to enhancing our ability to view and image the world, but digital processing provides us with a new tool that vastly expands our ability to form and enhance images.
Fredo Durand is an associate professor in the Electrical Engineering and Computer Science Department of the Massachusetts Institute of Technology, and a member of the Computer Science and Artificial Intelligence Laboratory. He received his PhD from Grenoble University (France) in 1999. He worked with Claude Puech and George Drettakis on both theoretical and practical aspects of 3D visibility. From 1999 till 2002, he was a post-doctoral researcher in the MIT Computer Graphics Group with Julie Dorsey, where he is now an associate professor.
His research interests span most aspects of picture generation and creation. This includes realistic graphics, real-time rendering, non-photorealistic rendering, as well as computational photography. His recent emphasis is on the use of tools from signal processing and inspiration from perceptual sciences. He received an inaugural Eurographics Young Researcher Award in 2004, an NSF CAREER award in 2005, an inaugural Microsoft Research New Faculty Fellowship in 2005 and a Sloan fellowship in 2006.
Animation is a Technology not a Genre- New Trends in Digital Entertainment
Animation techniques are widely used in digital media and play an integral role in the entertainment industry. They are the driving technology behind animated features and television series (narrative animation), visual effects (photorealistic animation) as well as games and other interactive appications (realtime animation).
Shared technologies and data types enable easy and affordable re-use of digital assets in various contexts. Animation media has given rise to transmedia storytelling - the creation of stories, characters and worlds across a broad range of applications. Audiences will increasingly engage their favored characters in previously impossible ways.
Thomas Haegele studied visual communications, political and social sciences and German literature. After working as a freelance artist and Creative Director, he established Polygon, one of the first German production houses for professional computer animation.
Since its formation in 1991, he has been professor for Animation and Visual Effects at Filmakademie Baden-Württemberg. Today, he is the Director of the Institute of Animation, Visual Effects and Digital Postproduction, as well as the Deputy Managing Director of the Filmakademie. He is also the founder and conference chair of FMX, Europe's largest conference on animation, effects, games and digital media.
Paneling Architectural Freeform Surfaces
Vienna University of Technology
Complex freeform structures are one of the most striking trends in contemporary architecture. Architects nowadays exploit digital technology originally developed for the automotive and airplane industry for tasks of architectural design and construction. This leads to a number of problems since the architectural application differs from the original target industries in many ways, including aesthetics, statics, scale and manufacturing technologies.
A particularly challenging and largely unsolved problem is that of paneling, i.e. the approximation of a given design surface by a union of simpler parts, so--called panels, which can be manufactured with the preferred technology at reasonable cost. The speaker will report on planar panels, mainy quadrilateral ones, and the closely related layout of single curved panels. Here, methods of discrete differential geometry turn out to play an important role. A main part of the talk will deal with very recent results on double curved panels of various types and optimized for different materials and manufacturing techniques. The presentation will be illustrated by results on data sets for architectural projects which are currently in a late design phase or already under construction.
Helmut Pottmann studied mathematics at Vienna University of Technology here
he received his PhD in 1983 and the habilitation in geometry in 1986. Between 1988 and 1992 he held faculty positions at the University of Kaiserslautern, Purdue University and the University of Hamburg. Since 1992 he is professor of geometry at Vienna University of Technology and head of the â€˜Geometric Modeling and Industrial Geometry research group. He has also been Adjunct Professor at the University of California, Davis and Visiting Chair Professor at Tsinghua University, Beijing. In September 2008 he accepted an offer to become director of the KAUST Geometric Modeling and Scientific Visualization Research Center.
His research interests are in Applied Geometry and Visual Computing, in particular in Geometric Modeling, Geometry Processing, Geometric Computing for Architecture and Manufacturing, Robot Kinematics, 3D Computer Vision and Visualization. He has co-authored two books and more than 170 refereed articles. Helmut Pottmann is on the editorial board of Advances in omputational Mathematics, Computer Aided Geometric Design, Geometry and Computing, SIAM Journal on Imaging Sciences and The Visual Computer.
