IMITATION METHOD OF FILM GRAIN ACCURATE TO BIT ON BASIS OF PRE-CALCULATED CONVERTED COEFFICIENTS Russian patent published in 2009 - IPC G06T5/00 H04N5/253 H04N7/26

Abstract RU 2372659 C2

FIELD: information technologies.

SUBSTANCE: film grain structure accurate to a bit is designed by means of organising, first, the set of converted coefficients accurate to a bit. Set of converted coefficients accurate to a bit is subject to frequency filtering and the following reverse conversion accurate to a bit in order to finally obtain film grain structure.

EFFECT: reducing film grain imitation complexity in the picture.
