Work Experiences
Current Projects
My work focus on both, research and implementation of multimedia analysis technology (video OCR, video ASR), content based video search technology, semantic information extraction etc. in following research projects:
MEDIAGLOBE - The digital archive is part of the THESEUS research program initiated by the German Federal Ministry of Economy and Technology (BMWi). MEDIAGLOBE deals with digitization, analysis, and semantic retrieval of historical, documentary audiovisual content.
Semantic Media Explorer (SEMEX) - The Semantic Media Explorer is a demonstrator that combines the latest media analysis processes to provides optimal access to video content.
tele-TASK - tele-TASK (tele-Teaching Anywhere Solution Kit) is an advanced mobile system for the production of Internet streaming videos and podcasts featuring a new and drastically simplified technology.
