Abstract
Se proporcionan dispositivos y métodos de intra predicción de un bloque de una imagen; el método incluye: obtener información de Intra Sub-Divisiones (ISP), donde la información de ISP indica si ISP es utilizada para partir un bloque actual; y seleccionar un conjunto de coeficientes de un filtro de interpolación con base en la información de ISP, donde el conjunto de coeficientes del filtro de interpolación es fG coeficientes o fC coeficientes; el método además incluye obtener muestras predichas del bloque actual aplicando el conjunto de coeficientes a muestras de referencia; cuando la información de ISP indica si ISP es utilizada para partir un bloque actual (es decir, ISP está encendida), el método remueve la dependencia de modo durante la selección de tipo de filtro de interpolación; esto podría incrementar la eficiencia de la codificación o decodificación.
