Abstract

um conjunto de funções básicas b-spline pelo produto do tensor (tpb) é determinado. um conjunto de parâmetros de predição tpb selecionados a serem utilizados com o conjunto de funções básicas tpb para a geração do dado de imagem predito nas imagens mapeadas a partir do dado de imagem de fonte nas imagens de fonte de uma graduação de cor de fonte é gerado. o conjunto de parâmetros de predição tpb selecionados é gerado pela minimização das diferenças entre o dado de imagem predito nas imagens mapeadas e o dado de imagem de referência nas imagens de referência de uma graduação de cor de referência. as imagens de referência correspondem as imagens de fonte e descrevem o mesmo conteúdo visual conforme descrito pelas imagens de fonte. o conjunto de parâmetros de predição tpb é codificado em um sinal de vídeo como uma parte do metadado de imagem juntamente com o dado de imagem de fonte nas imagens de fonte. as imagens mapeadas são levadas a serem reconstruídas e definidas com um dispositivo de recepção do sinal de vídeo.
