Abstract

Se proporciona un método para elaborar un bloque de predicción suave de muestras en una imagen en un codificador o decodificador de imágenes o video. El método incluye determinar los parámetros r de un modelo polinómico por r = (BTB)-1*(BT*x), en donde B es una matriz de bases y x es una fuente de muestras en forma vectorial. El método incluye predecir un bloque x' con base en los parámetros r y la matriz de bases B.
