METHOD TO PROCESS DATA OF OPTICAL CHARACTER RECOGNITION (OCR), WHERE OUTPUT DATA INCLUDES CHARACTER IMAGES WITH AFFECTED VISIBILITY Russian patent published in 2012 - IPC G06K9/34 

Abstract RU 2445699 C1

FIELD: information technologies.

SUBSTANCE: in the method searching is carried out by output data for identification of character images having image quality, which exceeds a predetermined level, and using these character images as a set of reference images for characters, location of a section area with affected visibility is identified on a character sample with affected visibility, information on location and area from a character sample with affected visibility is used to find appropriate areas on reference images prior to comparison of appropriate reference images with the character sample having affected visibility, neglecting the image content during comparison in the found appropriate areas, and the reference image is used, having greatest similarity with the character image having affected visibility as proper identification of the character with affected visibility.

EFFECT: increased quality of data recognition in the system of optical character recognition.
