METHOD AND DEVICE FOR AREA IDENTIFICATION Russian patent published in 2018 - IPC G06F3/00 

FIELD: physics.

SUBSTANCE: method for area identification comprises: identifying a predetermined edge on the identification image, identifying, at least, one information area on the identification image based on the predetermined edge, and trimming the information area to obtain one character area, binarizing the information area to obtain the binarized information area, calculating the first histogram of the binarized information area along the horizontal direction, identifying n rows of the character areas in accordance with successive sets of rows in the first histogram, calculating the second histogram in the vertical direction for the i-th series of character areas, identifying ni character areas in accordance with the sequential sets of columns in the second histogram, each of which consists of columns, in which the total number of pixel points of the foreground is greater than the second threshold value.

EFFECT: expanding the arsenal of technical means for identifying the information area of the image.
