Abstract

Se describen sistemas y métodos para aplicar filtros de suavizamiento a datos de video reconstruidos. Los valores de muestra en los bloques de video reconstruidos adyacentes se modifican de acuerdo con múltiples pasadas de un filtro de suavizamiento. Una pasada de filtrado puede corresponder al procesamiento o construcción de la totalidad o un subconjunto de muestras para ser suavizadas. El número de procesamientos o construcciones para cada muestra en una pasada dada puede corresponder al índice u orden de pasada.
