Current video database systems are able to manipulate
syntactic aspects of temporal media like video and audio. However, few of these
systems are able to manipulate video information according to its semantic
content. Furthermore, manually describing video content is tedious and not
practical for the video data due to the temporal, spatial, and massive
characteristic of the video, meanwhile content description always depends on
users' interpretation. Our video description model is based on "object-oriented
model based on prototypes" which is proposed in the object-oriented
programming field. A prototype is a prefabricated object with a predefined
structure, content, and behavior from which new objects can be constructed from
other prototypes. By using prototypes, the user is able to describe video
stories easily implementing and modifying prototypes of typical scenes that
usually appear in several stories. Our method uses two hierarchical structures,
one based on prototypes' inheritance structure and another based on prototypes'
internal structure. From this point of view, our system includes a hierarchical
prototype menu, which guides the user to reach easily requested prototypes;
hence, the story remains the same regardless of different users' interpretation.
