Abstract

"TéCNICA PARA A ADIçãO DE UM RUìDO DE CONFORTO DE BITS EXATOS". A adição de um ruído de conforto a uma imagem serve para ocultar artefatos de compactação. A fim de facilitar a adição do ruído de conforto, informações suplementares que acompanham uma imagem de vídeo contêm pelo menos um parâmetro que especifica um atributo relativo ao ruido de conforto. Tipicamente, as informações suplementares incluem parâmetros que funcionam de modo a ligar e desligar o ruído de conforto, assim como indicar o nível de ruído a adicionar, com base no nível esperado de artefatos de compactação.
