Abstract
método e aparelho para predição intra usando um filtro de interpolação. um método, um aparelho, um produto de programa de computador e uma mídia legível por computador não transitória para codificação de vídeo são fornecidos. o método compreende realizar um processo de predição intra de um bloco compreendendo amostras a serem preditas, em que um filtro de interpolação é aplicado para amostras de referência do bloco durante o processo de predição intra do bloco. o filtro de interpolação é selecionado com base em um deslocamento de subpixel entre as amostras de referência e as amostras a serem preditas, e um tamanho de um lado de referência principal usado no processo de predição intra é determinado de acordo com um comprimento do filtro de interpolação e um modo de predição intra que fornece, fora de um conjunto de modos de predição intra disponíveis, o maior valor não inteiro do referido deslocamento de subpixel, em que o lado de referência principal compreende as amostras de referência.
