Abstract

This paper describes a video annotation tool based on a new and flexible model, that gives several perspectives over the same video content. The model was designed in a way that allows having multiple views over the same video data, enabling users with different requirements to have the most appropriate interface. These views, video-lenses, highlight a specific aspect of the video content that is being annotated. Annotations are made using a timeline based interface with multiple tracks, where each track corresponds to a given video-lens. The format used to store and exchange the information is the MPEG-7 standard. The annotation tool (VAnnotator) is being developed in the scope of Vizard, an ambitious project that aims to define a new paradigm for video navigation, annotation, editing and retrieval. The Vizard project includes users, both from the production/archiving area and from the consumer electronics area, that help to define and validate the annotation requirements and functionality.
