Abstract
Los presentes principios se refieren a un método para codificación intra-predictiva de una unidad de codificación comprendiendo datos de imagen, dicha codificación intra-predictiva dependiente de un árbol de predicción y un árbol de Transformación, caracterizado porque el método comprende además: -obtener dicho árbol de predicción particionando espacialmente la unidad de codificación de acuerdo con un tipo de división no cuadrado; -determinar dicho árbol de Transformación de tal unidad de codificación con el fin de que cada una de las hojas esté incorporada en una unidad única de dicho árbol de predicción obtenida; y -señalizar en una señal el tamaño de las hojas de dicho árbol de Transformación y dicho un tipo de partición no cuadrada.
