Field binding algorithms for recognizing conditionally rigid administrative documents

Definitions of flexible and rigid documents used in technologies for entering administrative documents into a computer are proposed. The features of creating, digitizing and analyzing rigid forms and rigid documents are considered. The limits of applicability of the model for linking images of rigid documents distorted during digitization are described. A model for linking flexible documents is considered, based on recognized words and graphic primitives connected by a set of order relations. The classification is based on various methods of preparing administrative documents for printing. The features of field binding and recognition for several types of documents are described, such as conditionally rigid documents, flexible documents produced by one form, flexible documents produced by a small and large number of forms. The case of recognition of conditionally rigid documents using flexible document input technologies is considered. The experiments carried out show that for some fields of notes in conditions of strong noise and significant distortion, the proportion of errors is reduced by half.
