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

FIELD: information technology.

SUBSTANCE: automatic photograph retouching method involves creating a data array from photographs of different themes of classes, creating a database of references therefrom by interactive processing, based on Photoshop CS2, of predefined textures which give a comfortable perception of images of objects on the photographs, constructing a function of a photometric correction signal between the original and reference photographs, determining barcodes of the original photograph and the reference photograph by decoding brightness I(x,y) of matrices of images with the size |m×n| of elements in the matrix of intensities of tonal transitions with dimensions ||k×k|| of elements of the original and reference retouched photographs, algebraic subtraction of the matrix of barcodes while setting a threshold for positive identification of the reference, creating a reference address with barcode extension therefrom, a threshold difference and a photometric correction signal function, automatic search of the reference for the analysed photograph and retouching thereof based on the calculated barcode at the address in a reference database and the photometric correction signal function.

EFFECT: automatic search for the reference for a processed photograph by creating code features of each reference located in a reference database, and subsequent automatic photometric correction of the processed photograph on a reference texture mask stored in the reference database.
