Abstract

resumo dispositivos e métodos para codificação e / ou de sinalização de deslocamento adaptativo de amostra em uma modalidade, o método para decodificar uma corrente de bits de vídeo compreende: (a) receber uma corrente de bits de vídeo; (b) derivar dados de vídeo processados a partir da corrente de bits; (c) particionar os dados de vídeo processados em blocos, em que cada um dos blocos é igual a ou menor do que uma imagem; (d) derivar um tipo de sao a partir da corrente de bits de vídeo para cada um dos blocos, em que o tipo de sao é selecionado a partir do grupo que consiste em um ou mais tipos de deslocamento de borda (eo) e um tipo de deslocamento de banda (bo) fundido único; (e) determinar uma subclasse de sao associada com o tipo de sao para cada um dos pixels em cada um dos blocos; (f) derivar deslocamento de intensidade da corrente de bits de vídeo para a subclasse associada com o tipo de sao; e (g) aplicar compensação de sao para cada um dos pixels em um bloco de vídeo processado, em que a compensação de sao baseia-se no deslocamento de intensidade do passo (f).
