3D videocommunication is one relevant application scenario in future 3D services. We are working on concepts, systems and algorithm development since more than 10 years. From 2000-2003, we have been involved in the first European research project dealing with 3D videoconferencing, IST VIRTUE project. After that, the im.point represented in 2004 a proof of concept for a real-time 3D videoconferencing system offering one person at three different sites to communicate to each other as they would do in a real-round table setup. Currently, we are involved in a new European FP7 research project “3DPresence”. The aim is to implement a multi-party, high-end 3D videoconferencing concept that will tackle the problem of transmitting the feeling of physical presence in real-time to multiple remote locations in a transparent and natural way.

The expertise in this area is as follows:

• setup of multi-view camera systems
• calibration of colometric and geometric distortion
• synchronous multi-view capture
• real-time high-definition depth estimation of stereo and trifocal camera setups
• image rectification and warping
• high-quality high-resolution novel view synthesis
• porting of algorithms to GPU
