Abstract
Se describe un método de transformación adaptable con base en una predicción en pantalla y un aparato que usa el método. Un método para codificar una imagen puede comprender un paso para determinar grupos de modo de predicción en pantalla y un paso para transformación utilizando un método para transformación diferente de acuerdo con el grupo de modo de predicción en pantalla. Como resultado, la transformación puede llevarse a cabo aplicando el método de transformación diferente de acuerdo con el grupo de modo de predicción en pantalla.
