METHOD FOR SYNCHRONIZING FILLED MACHINE-READABLE FORM AND ITS TEMPLATE IN CASE OF PRESENCE OF DEVIATIONS Russian patent published in 2005 - IPC

FIELD: optical symbols recognition.

SUBSTANCE: one form of template or image is assigned as changed form, and other one - not changed form; areas are selected at image form, which contain deviations; all objects on form are separated as several types based on reliability of identification on image; each object at image form is assigned with level of identification reliability; for each area and for objects of each type: correspondence between equal objects of image form and template form is determined, particular coefficients of correction of deviations of space parameters of changed form are calculated, common shared coefficient of correction is calculated for changed form and space parameters of form are corrected with consideration of said common unified coefficient.

EFFECT: higher efficiency.
