Abstract

processamento de granulação de filme e ruído de conforto para vídeo 3 dimensional. o ruído, tanto na forma de ruído de conforto quanto de granulação de filme, é adicionado em uma imagem tridimensional de acordo com a informação da profundidade da imagem para reduzir a sensibilidade humana aos artefatos de codificação, dessa forma melhorando a qualidade da imagem subjetiva.
