Abstract

resumo patente de invenção: "codificação de conteúdo de vídeo perceptualmente quantizado em codificação de vdr de múltiplas camadas". imagens de vdr de entrada são recebidas. um conjunto candidato de valores de parâmetro de função para uma função de mapeamento é selecionado a partir de múltiplos conjuntos candidatos. um conjunto de blocos de imagens de derivações padrão diferentes de zero em palavras-código de vdr em pelo menos uma imagem de vdr de entrada é construído. os valores de código mapeados são gerados aplicando-se a função de mapeamento com o conjunto candidato de valores de parâmetro de função para as palavras-código de vdr no conjunto de blocos de imagens na pelo menos uma imagem de vdr de entrada. com base nos valores de código mapeados, um subconjunto de blocos de imagem de desvios-padrão abaixo de um limite de valor em palavras-código mapeados é determinado como um subconjunto do conjunto de blocos de imagem. com base, pelo menos em parte, no subconjunto de blocos de imagem, é determinado se o conjunto candidato de valores de parâmetro de função é ideal para a função de mapeamento para mapear a pelo menos uma imagem de vdr de entrada.
