Abstract

"MéTODO E APARELHO PARA MODELAR PADRõES DE GRANULAçãO DE FILME NO DOMìNIO DA FREQüêNCIA". Padrões de granulação de filme podem ser modelados no domínio da freqüência através de estimar as freqüências de corte que definem um filtro de banda de passagem 2D. Os parâmetros de granulação de filme podem ser transportados de acordo com o padrão ITU-T H.264] MPEG-4 AVC em uma mensagem SEI permitindo re-inserção de granulação de filme em um decodificador.
