Research Interests

Visual Computing (Computer Graphics, Computer Vision, Video Processing, Interaction)
Video processing and post-production tools, e.g., MovieReshape
Interactive approaches for editing of reflections and other surfaces signals in a virtual scene
Image-based 3D modeling, e.g., VideoTrace

Media Coverage

An introduction to some of my recent research projects is available in the Max Planck Research magazine (English ) (German ).

The MovieReshape project has received world-wide media attention.
Our system for Computer-suggested Facial Makeup was presented at the CeBIT 2011 fair and received extensive coverage by national and international media outlets.
An interactive demonstrator of the Interactive Relection Editing approach was shown at the CeBIT 2010 fair. (German press release)
