I am co-founder and CEO of kooaba. Used to be CTO there. I still cooperate closely with the Computer Vision Lab at ETH Zurich, where I was a PhD student and post-graduate researcher. My research interests include object recognition, multimedia mining, image retrieval, applications of computer vision on mobile devices and the web.

commercially
In 2006 I co-founded kooaba. Kooaba offers mobile visual search (or object recognition, for that matter) and is a direct consequence from research here at the Computer Vision Lab at ETH.
In 1998 I founded Quack Internet Solutions. Quack Internet Solutions offers web-site design, programming and related services like consulting or on-line marketing. In recent years I put a strong focus on standards-based web-development with CSS.
previously
Before that I was involved in the project Cortina, a system for large-scale, content-based image retrieval on the World Wide Web. It came into existence during a stay in the Vision Lab at the University of California at Santa Barbara, USA. My Master's thesis discusses the system and looks into the semantics within.
Master's Thesis: Cortina (2004)
You can check out the system here: www.cortina.ch. (Note: Since it is still a research system, it might be offline every now and then).
Lukas Hohl and yours truly implemented a system for 3D-augmentation of video sequences. 3D information was obtained from non-coplanar regions, tracked with Vittorio Ferrarisreal-time affine region tracker. This was a semester-project in the Computer Vision Lab of ETH Zurich back in 2003.
