Abstract

CANDIDATOS DE MESCLAGEM COM MÚLTIPLAS HIPÓTESES. Um decodificador de vídeo recebe dados a-serem-decodificados a partir de um fluxo de bits para um bloco de pixels a ser decodificado como um bloco atual de uma imagem atual do vídeo. O decodificador de vídeo gera uma primeira predição do bloco atual com base em um primeiro modo de predição que é selecionado a partir de uma primeira lista de candidatos. O decodificador de vídeo gera uma segunda predição do bloco atual com base em um segundo modo de predição que é selecionado a partir de uma segunda lista de candidatos. O decodificador de vídeo gera uma predição combinada para o bloco atual com base na primeira predição e na segunda predição. O decodificador de vídeo reconstrói o bloco atual usando a predição combinada.
