Abstract

Se describen diferentes implementaciones, particularmente se presentan implementaciones para codificación y decodificación de video incluyendo un método para desbloquear una imagen. De acuerdo con una implementación, en un método para desbloquear una imagen, el al menos un límite se determina entre un primer bloque de muestras y un segundo bloque de muestras; una fuerza del límite se determina de acuerdo con al menos un modo de predicción del primer bloque y un modo de predicción del segundo bloque; y muestras del primer y segundo bloques adyacentes a al menos un límite se filtraron de acuerdo con la fuerza del límite. Ventajosamente, en caso, que el modo de predicción del primer bloque sea un modo de predicción ponderado, la fuerza del límite depende además del peso relativo de muestras utilizadas en la predicción del primer bloque de muestras de acuerdo con el modo de predicción ponderado del primer bloque y recíprocamente para el segundo bloque.
