METHOD AND APPARATUS FOR MODELING FILM GRAIN PATTERNS IN THEFREQUENCY DOMAIN

摘要

Film grain patterns can be modeled in the frequency domain by estimating the cut frequencies that define a 2D band-pass filter. The film grain parameters can be conveyed in accordance with the ITU-T H.264 ³ MPEG-4 AVC standard in an SEI message allowing film grain reinsertion at a decoder.
