Abstract

codificação de índices de corte para filtro de malha adaptativo em codificação de vídeo. uma codificadora de vídeo é configurada para codificar um índice de recorte de filtro de malha adaptativo (alf) como um número inteiro sem sinal de comprimento fixo. a codificadora de vídeo pode aplicar, com base no índice de recorte de alf, um alf a um bloco de uma figuração dos dados de vídeo.
