Abstract

uso de filtro de interpolação com base em dct e de filtro de interpolação bilinear aprimorado em compensação de movimento afim. a presente revelação refere-se a uso adaptativo de compensação de movimento afim baseada em pixel e baseada em bloco. predição de transformada afim baseada em sub-bloco é realizada em um bloco afim com um primeiro tamanho de sub-bloco se o primeiro tamanho de sub-bloco for maior que ou igual a um primeiro limiar de tamanho de sub-bloco. se o primeiro tamanho de sub-bloco for menor que o primeiro limiar de tamanho de sub-bloco, é determinado se um campo de vetor de movimento baseado em pixel não é aplicado para realizar compensação de movimento para o bloco afim. se o campo de vetor de movimento não for aplicado, uma predição de movimento afim baseada em sub-bloco é realizada com um segundo tamanho de sub-bloco que é baseado no primeiro tamanho de sub-bloco. se o campo de vetor de movimento baseado em pixel for aplicado, compensação de movimento é realizada para um sub-bloco do bloco afim usando o campo de vetor de movimento baseado em pixel.
