Systems and methods for describing image content establish image description records which include an object set ( 24 ), an object hierarchy ( 26 ) and entity relation graphs ( 28 ). For image content, image objects can include global objects (O 0 8 ) and local objects (O 1 2 and O 2 6 ). The image objects are further defined by a number of features of different classes ( 36, 38 and 40 ), which in turn are further defined by a number of feature descriptors. The relationships between and among the objects in the object set are defined by the object hierarchy ( 26 ) and entity relation graphs ( 28 ). The image description records provide a standard vehicle for describing the content and context of image information for subsequent access and processing by computer applications such as search engines, filters, and archive systems.
