Abstract

DATOS DE IMAGENES, TALES COMO DATOS BINARIOS DE IMAGENES DE MASCARAS, SON COMPRIMIDOS MEDIANTE PARTICION EN BLOQUES. SE INICIALIZA UN CODIFICADOR ARITMETICO PARA CADA BLOQUE, Y SE TERMINA AL FINAL DEL MISMO. PARA CADA BLOQUE, HAY UNA PLANTILLA FIJA MODELO DE PARES DE TABLAS PDF, QUE ES ELEGIDA AL PRINCIPIO DEL BLOQUE DE ACUERDO CON LA COMPENSACION DEL MOVIMIENTO Y OTRAS ENTRADAS. UN MODELO TIENE UNA PLANTILLA EXCLUSIVAMENTE CON MUESTRAS DE CORRELACION ESPACIAL, Y EL OTRO CONTIENE MUESTRAS DE CORRELACION ESPACIAL Y TEMPORAL. SE EFECTUAN ESTIMACIONES PARA LOS VALORES DE LAS MUESTRAS QUE BORDEEN AL BLOQUE ACTUAL DE ACUERDO CON REGLAS SENCILLAS PARA LA PLANTILLA PARTICULAR.
