Abstract

"TéCNICA PARA SIMULAçãO DE GRãO DE FILME USANDO UMA BASE DE DADOS DE PADRõES DE GRãO DE FILME". Pixels individuais em um bloco de imagens passam por mistura com grão de filme de um bloco de grão de filme selecionado aleatoriamente entre uma coleção (18) de blocos de grão de filme previamente estabelecidos de acordo com uma característica luma do bloco de imagens. Antes da mistura, o bloco de grão de filme selecionado passa por desbloqueios por um filtro de desbloqueio (28). Após a mistura, um recortador (32) recorta os pixels individuais antes da exibição. A coleção (18) de blocos de grão de filme é criada ajustando a escala de um conjunto de padrões de grão de filme de acordo com pelo menos um parâmetro de mensagem de informação de grão de filme que acompanha o bloco de imagens.
