Abstract
En modalidades de la presente solicitud se describen un método de predicción entre cuadros, un codificador, un decodificador y un medio de almacenamiento informático; el método comprende: un decodificador que analiza un flujo de código para obtener un parámetro de modo de predicción del bloque actual; si el parámetro del modo de predicción indica que se determina un valor interpredicción del bloque actual utilizando un modo de predicción intercuadros, determinar un primer vector de movimiento de un sub-bloque del bloque actual, en el que el bloque actual comprende una pluralidad de sub-bloques; determinar, sobre la base del primer vector de movimiento, un primer valor de predicción del sub-bloque y una desviación del vector de movimiento entre una posición de píxel y el sub-bloque, donde la posición de píxel es la posición de un píxel dentro del sub-bloque; determinar un coeficiente de filtro de un filtro bidimensional según la desviación del vector de movimiento, en el que el filtro bidimensional se usa para realizar un procesamiento de predicción secundario según una forma preestablecida; y determinar un segundo valor de predicción del sub-bloque sobre la base del coeficiente de filtro y el primer valor de predicción, y determinar el segundo valor de predicción como un valor de predicción intercuadros del sub-bloque.
