Abstract

La presente invención proporciona un método de decodificación de imagen de video. En el método, un tamaño de un subbloque de imagen de compensación de movimiento afín en un bloque de imagen afín se determina con base en una diferencia del vector de movimiento, precisión del vector de movimiento, una distancia entre los puntos de control y el bloque de imagen afín, y un tamaño del bloque de imagen afín, donde el tamaño incluye una longitud en una dirección horizontal y una longitud en una dirección vertical, de manera que una longitud del bloque de imagen afín en una dirección horizontal/vertical es un múltiplo entero de la longitud del subbloque de imagen de compensación de movimiento afín en la dirección horizontal/vertical y finalmente, se lleva a cabo el procesamiento de decodificación en el bloque de imagen afín con base en el tamaño del subbloque de imagen de compensación de movimiento afín. De acuerdo con el método, el tamaño del subbloque de imagen de compensación de movimiento afín en el bloque de imagen afín puede ajustarse de manera adaptable hasta un tamaño óptimo con base en un atributo del bloque de imagen afín. De esta manera, se puede asegurar su calidad de decodificación, puede reducirse la complejidad de decodificación, y puede mejorarse efectivamente la eficiencia de decodificación.
