IDENTIFICATION AND/OR VERIFICATION OF IMAGES Russian patent published in 2015 - IPC G06K9/68 

FIELD: physics.

SUBSTANCE: claimed process consists in making of electronic image from that output to system with application of perception of presented image brightness field, converting of said brightness field into digital codes corresponding to brightness levels of the image every microelement and its framing with memorization in data base. Note here that before comparison, electronic image is reduced to standard electronic image scale. Here, info parts are isolated therefrom to remove background parts that feature identical or fitting brightness codes of sensels. Maximum and minimum values of said codes are defined for every info part for all sensels, summed up and halved to determine the average brightness code. Numbers of sensels are calculated separately which feature brightness code higher than or equal to average value as well as numbers of sensels with this code lower than said average value. Then, obtained numbers for standard and presented electronic images are compared in pairs with allowance from preset tolerance. Control is considered positive in case said pairs fit in said tolerance otherwise it is considered negative.

EFFECT: automatic comparison of presented image with standard one.
