Method and apparatus for modelling film grain patterns in the frequency 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|MPEG-4 AVC standard in an SEI message allowing film grain reinsertion at a decoder.
