Abstract

sinalização de camadas de referência para predição de cor 3d para escalabilidade de gama de cores. são descritas técnicas para realizar predição de cor tridimensional (3d) restrita para escalabilidade de gama de cores em codificação de vídeo. as técnicas de predição de cor para escalabilidade de gama de cores podem ser usadas pelos codificadores de vídeo para gerar imagens de referência entre camadas quando uma gama de cores para uma camada de referência de dados de vídeo é diferente de uma gama de cores para uma camada de aperfeiçoamento dos dados de vídeo, ou quando uma profundidade de bits da camada de referência é diferente de uma profundidade de bits da camada de aperfeiçoamento. de acordo com as técnicas, um codificador de vídeo pode realizar pre dição de cor 3d com profundidades de bit restritas de componentes de cor de entrada e de saída da tabela de consulta 3d. de acordo com técnicas adicionais, no caso de múltiplas camadas, um codificador de vídeo pode realizar predição de cor 3d com aplicação restrita às imagens de referência em apenas uma ou mais camadas de referência identificadas.
