Abstract
aparelho e método para filtragem em codificação de vídeo. a presente revelação se refere a um filtro, para um codificador e um decodificador usando o filtro, para um método de filtragem e um programa correspondente, assim como para codificar e decodificar usando o método de filtragem ou o filtro. a filtragem inclui obtenção de um bloco reconstruído estendido estendendo-se o bloco reconstruído atual para inclui pelo menos amostras padding a partir do bloco reconstruído atual. após o padding, um pixel atual do bloco reconstruído estendido e seus pixels vizinhos são carregados em um buffer linear e transformados com uma transformada 1d. a filtragem é realizada em domínio de frequência usando uma tabela de consulta e os pixels filtrados são transformados de volta.
