Abstract

Para codificar una imagen, una unidad de árbol de codificación (CTU) en la imagen es particionada por una estructura de árbol cuaternario, y los nodos de hoja de árbol cuaternario pueden ser además particionados por una estructura de árbol del tipo múltiple (MTT). Para incrementar el conjunto de nodos y hojas de árbol de codificación alcanzables, proponemos incrementar la profundidad máxima jerárquica MTT permitida para que sea dos veces la diferencia entre el tamaño de CTU y el tamaño mínimo permitido para una CU. La profundidad máxima jerárquica MTT permitida puede ser especificada para todos los niveles QT con el fin de proporcionar mayor flexibilidad en el árbol de partición. Alternativamente, únicamente dos niveles de profundidad máxima MTT permitida son señalizados: uno cuando particiones QT son permitidas, y otra cuando no hay más particiones QT permitidas. Además, un límite superior puede establecerse para el tamaño mínimo de bloque de codificación permitido, con base en el tamaño de unidad de árbol de codificación o el tamaño de transformada máximo permitido.
