Automated Annotation of Synchronized Multimedia Presentations

چکیده
Semantic annotation of multimedia data for improving search engine performance is an important issue. We have focused on the automated annotation of video recordings of university lectures. Most times these lectures are supported by a desktop presentation provided by the lecturer. This presentation in general contains an outline of the given lecture and thus, enables automated annotation of the corresponding video recording. We have implemented a tool for automated MPEG-7 annotation of video recorded lectures, which enables efficient content based search within a video database. Given a particular search term our search engine prototype is able to deliver only the relevant sequences of the matching video recordings.
