Abstract

métodos e aparelho para filtragem adaptativa eficiente para codificadores e decodificadores de vídeo métodos e aparelho são proporcionados para filtragem adaptativa eficiente para codificadores de vídeo. um aparelho inclui um cidificador de vídeo (100) para a codificação de dados de imagem para pelo menos uma porção da imagem usando filtragem adaptativa. o codificador de vídeo (100) inclui um filtro adaptativo para realizar a filtragem adaptativa. um conjunto final de coeficiente de filtro usado para a filtragem adaptativa é determinado ao estimar iterativamente uma pluralidade de conjuntos de coeficiente de filtro e selecionar o último estimado da pluralidade de conjuntos de coeficiente de filtro como o conjunto final de coeficiente de filtro quando a última iteração correspondendo ao último estimado da pluralidade de conjuntos de coeficiente de filtro resulta em um aprimoramento da qualidade acima do valor limiar para a porção.
