ABSTRACT:
A system for logically identifying document elements in a document image using structural models includes assistant function for users to describe the structural models, a geometric relationship comparator for comparing geometric relationships in a document to the geometric relationships in a structural model, a matching system for determining which structural model matches the document image, and a logical tag assigning system for assigning logical tags to the document elements of the document image based on the matching structural model. The method for logically identifying the document elements in the document image using structural models comprises identifying the major white regions in the document image, using geometric relationships between the major white regions in the document image, identifying a structural model which matches the document image, and assigning logical tags to the document elements in the document image based on the matching structural model.
