Definition:The COSMOS-7 is a content modeling scheme that uses the MPEG-7 standard to describe high and low level features.
Content modeling is the cornerstone for describing multimedia semantics and accessing content based on user criteria [1]. The COSMOS-7 is a content modeling scheme that uses the MPEG-7 standard to describe all sorts of high and low level features. It is also an interface for creating multimedia semantics that also allows querying of the content.
Figure 1 shows the semantic aspects that COSMOS-7 is modeling, using MPEG-7 [2]. It is assumed that a video is already segmented into smaller and meaningful parts. The media stream contains objects with their absolute position. Objects and their properties are described with the ObjectDS and ConceptDS respectively. The absolute location of an object at a given snapshot is outlined with the StillRegionDS, which is linked with the object it depicts. The objects layout in the video shot defines the spatial relationships...
