Abstract

LA ACEPTABILIDAD DE LA APARIENCIA DE LOS OBJETOS (12), TALES COMO PRODUCTOS PARA EL CONSUMIDOR, ES DETERMINADA MEDIANTE LA FORMACION DE UNA FUNCION DISCRIMINANTE INICIAL (F) COMO UN COMPUESTO DE UN RELATIVAMENTE PEQUEÑO NUMERO DE IMAGENES (I), LAS CUALES SON CONOCIDAS POR SER ACEPTABLES. ESTA FUNCION DISCRIMINANTE INICIAL ES PUES UTILIZADA PARA AGRUPAR LA INFORMACION ESTADISTICA (P, A, B, C) ACERCA DE COMO UN PRIMER NUMERO RELATIVAMENTE GRANDE DE IMAGENES SE COMPARA CON LA FUNCION DISCRIMINANTE INICIAL. DESPUES DE ESTO, ESTA INFORMACION ESTADISTICA ES UTILIZADA (318-324) PARA SELECCIONAR O AYUDAR EN LA SELECCION DE LAS IMAGENES ACEPTABLES A PARTIR DE UN SEGUNDO NUMERO RELATIVAMENTE GRANDE DE IMAGENES , Y LAS IMAGENES SELECCIONADAS COMO ACEPTABLES SON UTILIZADAS (334) PARA AFINAR LA FUNCION DISCRIMINANTE. LA FUNCION DISCRIMINANTE AFINADA ES ENTONCES UTILIZADA (E.J. DURANTE LA INSPECCION DEL PRODUCTO EXISTENTE (402-414)) PARA DETERMINAR QUE OBJETOS TIENEN UNA APARIENCIA ACEPTABLE Y CUALES NO.
