Abstract

Se puede decodificar una secuencia de video codificada que incluya una pluralidad de imágenes. Se pueden proporcionar primero y segundo bloques adyacentes de una imagen de una secuencia de video codificada. Se puede definir una línea de pixeles que incluya pixeles del primero y segundo bloques que se extiendan a través de un límite entre el primero y segundo bloques. Se puede calcular un primer valor de referencia con base en un primer pixel de los pixeles del primer bloque. Se puede calcular un segundo valor de referencia con base en un segundo pixel de los pixeles del segundo bloque. Los valores de pixel filtrados para cada pixel de la línea de pixeles entre el primer pixel y el segundo pixel se pueden calcular usando interpolación con base en el primero y/o segundo valores de referencia. Se pueden generar bloques filtrados usando los valores de pixel filtrados, y se puede generar una secuencia de video decodificada con base en los bloques filtrados.
