Abstract
filtragem de interpolação de baixa complexidade com tamanho de dericação adaptativo durante uma fase de predição de codificação de vídeo, um codificador de vídeo pode usar filtros de interpolação relativamente mais longos para gerar os valores de sub-pixel preditivo utilizando valores de pixels inteiros de referência de um bloco de referência de dados de vídeo posicionado em paralelo em relação a uma ordem de varredura associada com o bloco e pode usar filtros de interpolação relativamente mais curtos para gerar os valores de sub-pixel preditivo utilizando valores de pixels inteiros de referência do bloco posicionado perpendicularmente em relação à ordem de varredura, em que um filtro de interpolação mais longo refere-se a um filtro com relativamente mais coeficientes de filtro, ou "derivações" e um filtro mais curto, geralmente refere-se a um filtro com o número relativamente menor de derivações.
