Abstract

Um decodificador de vídeo pode ser configurado para executar uma operação de filtragem por determinar um primeiro valor de diferença que corresponde a uma diferença entre o valor de amostra da amostra selecionada e um valor de amostra de uma primeira amostra vizinha; multiplicar o primeiro valor de diferença por um primeiro parâmetro de ponderação para determinar um primeiro valor de diferença ponderado; determinar um segundo valor de diferença que corresponde a uma diferença entre o valor de amostra da amostra selecionada e um valor de amostra de uma segunda amostra vizinha; multiplicar o segundo valor de diferença por um segundo parâmetro de ponderação para determinar um segundo valor de diferença ponderado; e adicionar o primeiro valor de diferença ponderado e o segundo valor de diferença ponderado para o valor de amostra da amostra selecionada para determinar o valor de amostra modificado.
