Abstract

SE PRESENTA UN CODIFICADOR Y UN DECODIFICADOR PARA UNA IMAGEN FIJA Y EN MOVIMIENTO. EL CODIFICADOR TIENE UNA MEMORIA PARA ALMACENAR UNA MATRIZ DE CUANTIFICACION POR DEFECTO QUE INCLUYE UNA SERIE DE DE ELEMENTOS DE CUANTIFICACION QUE TIENEN VALORES PREDETERMINADOS. TAMBIEN SE SUMINISTRA UN GENERADOR PARA PRODUCIR UNA MATRIZ DE CUANTIFICACION PARTICULAR DESPUES DE UN NUMERO DE MARCOS. LA MATRIZ DE CUANTIFICACION PARTICULAR ES LEIDA EN UNA FORMA DE ZIGZAG PREDETERMINADA, Y LA LECTURA FINALIZA EN UNA POSICION SELECCIONADA QUE ES LA MITAD DEL MODELO DE ZIGZAG. SE AÑADE UN CODIGO DE FIN DESPUES DE LOS ELEMENTOS DE CUANTIFICACION LEIDOS DE UNA PARTE INICIAL DE LA MATRIZ DE CUANTIFICACION PARTICULAR. LOS ELEMENTOS DE CUANTIFICACION EN LA MATRIZ DE CUANTIFICACION POR DEFECTO SON LEIDOS EN LA MISMA FORMA DE ZIGZAG DESDE UNA POSICION INMEDIATAMENTE DESPUES DE LA POSICION SELECCIONADA, PRODUCIENDO UNA PARTE POSTERIOR DE LA MATRIZ DE CUANTIFICACION POR DEFECTO. LA PARTE INICIAL DE LA MATRIZ DE CUANTIFICACION PARTICULAR Y LA PARTE POSTERIOR DE LA MATRIZ DE CUANTIFICACION POR DEFECTO SE SINTETIZAN PARA FORMAR UNA MATRIZ DE CUANTIFICACION SINTETIZADA.
