METHOD AND SYSTEM FOR IMAGE PROCESSING Russian patent published in 2016 - IPC G06T3/00 H04N19/59 

FIELD: information technology.

SUBSTANCE: invention relates to digital image processing. Image processing method using first and second base patch data, number of patches in first database is equal to number of patches in second database comprises steps of: carried out or low-frequency band-pass filtering original image; filtered image is divided into blocks of same size as size of patches in first data base patches; generating texture for each block, performing following steps: performing pre-processing; for each patch in second data base is calculated as sum of coefficients projections of pixels within block pieces pre-processed image and corresponding pixel values of first patch from database; calculate output pixel texture block as a sum of products of projection coefficients and patches from second database; perform normalisation of texture; perform post-processing of generated texture; and add texture to post-process original pixel values within block.

EFFECT: technical result is high resolution and level of detail of input image.
