Constraint propagation vs syntactical analysis for the logical structure recognition of library references
Abstract
This paper describes a constraint propagation method for logical structure extraction of Library references without the use of ocr. The accent is put on the search of anchor points from visual indices extraction. A mixed strategy is performed. For each anchor points. the system proposes in a bottom-up manner the most probable model hypothesis and tries to verify in a top-down manner its left and right contexts.
