AUTOMATIC DIGITAL PHOTOGRAPH RETOUCHING METHOD Russian patent published in 2014 - IPC G06T5/00 G06T7/00 G06T11/00 

FIELD: physics, computer engineering.

SUBSTANCE: invention relates to digital image processing means. The method includes creating a digital photograph data array; creating a reference base; forming a code feature matrix of reference photographs by recoding brightness matrices into code feature matrices; constructing a photometric correction function for each reference photograph; forming a code feature matrix of the original photograph by recoding the brightness matrix into a code feature matrix; algebraic subtraction of the code feature matrices of the reference photographs and the original photograph to establish a threshold for reliable identification the reference photograph most similar to the original photograph; forming an address of a reference photograph with an extension from its code feature matrix and photometric correction function; retouching the original photograph based on the calculated code feature matrix and the photometric correction function at the address in the reference base.

EFFECT: providing automatic correction of an original photograph based on a reference photograph photometric correction function.
