Abstract

filtros de interpolação comutáveis. tem-se um método e aparelhagem para o aperfeiçoamento da eficiência de compressão em um esquema de compressão de vídeo capacitando o uso de filtros de interpolação comutáveis. os filtros de interpolação são utilizados nas partições múltiplas de blocos de vídeo, capacitando a uma melhor previsão compensada de movimento e eficiência melhorada de codificação de vídeo aperfeiçoada. em uma modalidade, um índice de filtro de interpolação é derivado para partições triangulares de um bloco a partir de parâmetros de candidato de informação de movimento, de modo que cada compensação de movimento unidirecional possa utilizar um valor diferente de índice de filtro de interpolação. em uma outra modalidade, um índice de filtro de interpolação é uma função de características, tais como formato ou área, de partições de vídeo.
