Real-time Expression Transfer for Facial Reenactment

In Zusammenarbeit mit dem MPI Informatik in Saarbrücken und der Universität Stanford wurde eine neue Technik entwickelt, mit der in einem Live-Video die Mimik eines Gesichtes auf ein anderes Gesicht übertragen werden kann. Die Arbeit wird Anfang November auf der Konferenz “Siggraph Asia” in Japan vorgestellt. Die zugehörigen YouTube- und Facebook-Videos haben mittlerweile mehr als 700.000 Clicks, genaueres zu der Technik findet sich auf der Projekt-Homepage. [More]

Spherical Fibonacci Mapping

Spherical Fibonacci point sets yield nearly uniform point distributions on the unit sphere. We introduce an inverse mapping from points on the unit sphere which yields the nearest neighbor in an arbitrarily sized spherical Fibonacci point set in constant time. [More]

Real-Time Pixel Luminance Optimization for Dynamic Multi-Projection Mapping

Using projection mapping enables us to bring virtual worlds into shared physical spaces. In this paper, we present a novel, adaptable and real-time projection mapping system, which supports multiple projectors and high quality rendering of dynamic content on surfaces of complex geometrical shape. Our system allows for smooth blending across multiple projectors using a new optimization framework that simulates the diffuse direct light transport of the physical world to continuously adapt the color output of each projector pixel.

The Chair for Computer Science 9 (Computer Graphics) works on the generation and manipulation of synthetic images, virtual worlds and computer animations with the help of computers.

This comprises methods for generating suitable models of the scene (geometric modeling), methods for displaying such scenes (image synthesis, rendering) as well as the processing of large data sets with aim to visualize the information content (scientific visualization). Our focus is on applications of computer graphics in medicine and engineering.

The Department was founded 1992 and currently employs 21 scientific assistants.
