Video description system and method
First Claim
1. A non-transitory computer readable media containing digital information with at least one description record representing video content embedded within corresponding video information, the at least one description record generated by the method comprising:
- generating one or more video object descriptions from said video information using video object extraction processing;
generating one or more video object hierarchy descriptions from said generated video object descriptions using object hierarchy construction and extraction processing, each video object hierarchy description describing at least one relationship between at least two objects in the video information; and
generating one or more entity relation graph descriptions from said generated video object descriptions using entity relation graph generation processing, wherein said one or more generated entity relation graph descriptions describes non-hierarchical relationships between said objects associated with said one or more generated video object descriptions.

Abstract
Systems and methods for describing video content establish video description records which include an object set (24), an object hierarchy (26) and entity relation graphs (28). Video objects can include global objects, segment objects and local objects. The video objects are further defined by a number of features organized in classes, which in turn are further defined by a number of feature descriptors (36, 38, and 40). The relationships (44) between and among the objects in the object set (24) are defined by the object hierarchy (26) and entity relation graphs (28). The video description records provide a standard vehicle for describing the content and context of video information for subsequent access and processing by computer applications such as search engines, filters and archive systems.
