Abstract

LOS ALGORITMOS DE CONVERSION ASCENDENTE DE PROPORCION DE CAMPOS CONOCIDOS MUESTRAN UNA REPRESENTACION DE MOVIMIENTO DEFECTUOSA E INDESEABLES ARTEFACTOS, POR EJEMPLO DOBLE IMAGEN Y ESTRUCTURA DE "DIENTES DE RATON". EL ALGORITMO DE LA INVENCION CALCULA CADA PIXEL (PUNTO) DE LOS CAMPOS INTERMEDIOS DESDE PIXELS ADYACENTES EN LOS CAMPOS EXISTENTES, USANTO UN FILTRO LINEAL ADAPTABLE, CARACTERIZADO POR LAS SIGUIENTES FASES: DE SUMAS DE DIFERENCIAS, UNA O MAS POR CADA PIXEL IMPLICADO EN EL FILTRO ADAPTABLE; OR CADA PIXEL IMPLICADO EN EL FILTRO ADAPTABLE; EDIA DE COEFICIENTES EN UNA DIMENSION; FILTRACION LINEAL DE COEFICIENTES EN DOS DIMENSIONES; NORMALIZACION DE COEFICIENTES; CALCULO DEL VALOR DE PIXELS INTERPOLADOS PRINCIPALES; CORRECCION DE INTERPOLACION EN EL CASO DE MOVIMIENTO RAPIDO.
