Abstract

SE SUMINISTRA UN APARATO DE DESCODIFICACION DE IMAGENES PARA DESCODIFICAR UNA SEÑAL DE IMAGEN CODIFICADA QUE TIENE UN IDENTIFICADOR DE IMAGEN BASADO EN UNA ESTRUCTURA DE DATOS DE LA SEÑAL DE LA IMAGEN. ESTE APARATO COMPRENDE UN ANALIZADOR DE DATOS PARA ANALIZAR LA SEÑAL DE LA IMAGEN CODIFICADA CON REFERENCIA AL IDENTIFICADOR DE IMAGEN PARA DECIDIR CUANDO LA SEÑAL DE LA IMAGEN CODIFICADA ES UNA SEÑAL DE FORMA ARBITRARIA CODIFICADA QUE INCLUYE TANTO CORRIENTES DE BITS DE FORMA CODIFICADA OBTENIDAS CODIFICANDO UNA SEÑAL DE FORMA QUE REPRESENTA LA FORMA DE CADA OBJETO COMO UNO DE LOS COMPONENTES DE LA IMAGEN REPRESENTADA COMO CORRIENTES DE BITS DE VALORES DE PIXEL CODIFICADAS QUE INCLUYEN SOLAMENTE CORRIENTES DE BITS DE FORMA CODIFICADA OBTENIDAS CODIFICANDO UNA SEÑAL DE FORMA QUE REPRESENTA UNA IMAGEN REPRESENTADA DE INFORMACION BINARIA. UN PRIMER DESCODIFICADOR PARA DESCODIFICAR LAS CORRIENTES DE BITS DE FORMA CODIFICADA MEDIANTE UN PRIMER PROCESO DE DESCODIFICACION; Y UN SEGUNDO DESCODIFICADOR PARA DESCODIFICAR LAS CORRIENTES DE BITS DE VALORES DE PIXEL CODIFICADAS MEDIANTE UN SEGUNDO PROCESO DE DESCODIFICACION. EL PRIMER PROCESO DE DESCODIFICACION Y EL SEGUNDO PROCESO DE DESCODIFICACION SON APROPIADAMENTE CONMUTADOS DE ACUERDO CON CADA SEÑAL DE LA IMAGEN CODIFICADA. POR LO TANTO, PUEDEN DESCODIFICARSE SEÑALES DE IMAGENES CODIFICADAS PLURALES QUE TENGAN ESTRUCTURAS DE DATOS DIFERENTES Y PRODUCIDAS POR DIFERENTES METODOS DE CODIFICACION EN LOS PROCESOS DE DESCODIFICACION QUE SE CORRESPONDEN CON UN METODO DE CODIFICACION SIMPLE.
