Abstract

Un método que comprende: codificar una imagen de entrada en una imagen constituyente codificada (1200); reconstruir, como parte de dicha codificación, una imagen constituyente decodificada correspondiente a la imagen constituyente codificada (1202); codificar una región espacial en un azulejo codificado (1204), comprendiendo la codificación: determinar un desplazamiento horizontal y un desplazamiento vertical indicativos de una posición de anclaje regional de la región espacial dentro de la imagen constituyente decodificada (1204a); codificar el desplazamiento horizontal y el desplazamiento vertical (1204b); determinar que una unidad de predicción en la posición de una primera coordenada horizontal y una primera coordenada vertical del azulejo codificado se predice en relación con la posición de anclaje regional, en donde la primera coordenada horizontal y la primera coordenada vertical son coordenadas horizontales y verticales, respectivamente, dentro de la región espacial (1204c); indicar que la unidad de predicción se predice en relación con una posición de anclaje de unidad de predicción que está en relación con los desplazamientos horizontal y vertical (1204d); obtener una posición de anclaje de unidad de predicción igual a la suma de la primera coordenada horizontal y el desplazamiento horizontal, y la primera coordenada vertical y el desplazamiento vertical, respectivamente (1204e); y determinar un vector de movimiento para la unidad de predicción (1204f); y aplicar el vector de movimiento en relación con la posición de anclaje de unidad de predicción para obtener un bloque de predicción (1204g).
