Abstract

MÉTODO E APARELHO DE INTER-PREDIÇÃO ADAPTATIVA EM CODIFICAÇAO DE VIDEO. Um método e aparelho de codificação de vídeo usando Inter-predição adaptativa são divulgados. Um processo de Inter-predição selecionado é determinado, em que o processo de Inter-predição selecionado seleciona um filtro de Interpredição a partir de vários filtros de Inter-predição para o bloco atual dependendo de primeiros dados de pixel que compreendem pixels reconstruídos vizinhos (NRP) do bloco atual. O processo de Inter-predição selecionado pode ser ainda determinado dependendo de pixels de compensação de movimento extras (EMCP) em torno de um bloco de referência compensado de movimento correspondente ao bloco atual. A distorção entre o NRP e o EMCP pode ser usada para determinar o filtro de Inter-predição selecionado. A distorção pode ser calculada usando uma soma de diferenças absolutas ou diferenças quadráticas entre o NRP e o EMCP.
