Abstract

LA INVENCION SE REFIERE A UN CODIFICADOR Y A UN DECODIFICADOR DE LOS DATOS DIGITALES DE UNA IMAGEN, EN DONDE EL CODIFICADOR/DECODIFICADOR PUEDE REALIZAR UNA TRANSFORMACION DE ALTA PRECISION CON MENOS CANTIDAD DE DATOS TRANSFERIDOS, CUANDO UN PARAMETRO DE LOS DATOS DIGITALES DE LA IMAGEN NO ES UN ENTERO PERO TIENE UNOS NUMEROS DE DIGITOS A LOS QUE SE PUEDE APLICAR LA TRANSFORMACION DE AFFINE. EL CODIFICADOR/DECODIFICADOR ESTA COMPUESTO POR LOS SIGUIENTES ELEMENTOS: (A) UN MEDIO DE COMPRESION DE IMAGENES, PARA CODIFICAR UNA IMAGEN DE ENTRADA Y PARA COMPRIMIR LOS DATOS, (B) UN MEDIO DE TRANSFORMACION DE COORDENADAS, PARA PRODUCIR LOS DATOS DE LAS COORDENADAS OBTENIDAS DECODIFICANDO LOS DATOS COMPRIMIDOS Y TRANSFORMANDO LOS DATOS CODIFICADOS A UN SISTEMA DE COORDENADAS, (C) UN MEDIO PRODUCTOR DE LOS PARAMETROS DE TRANSFORMACION, PARA PRODUCIR LOS PARAMETROS DE TRANSFORMACION A PARTIR DE LOS DATOS DE LAS COORDENADAS, (D) UN MEDIO PRODUCTOR DE UNA IMAGEN PREDECIDA, PARA PRODUCIR UNA IMAGEN PREDECIDA A PARTIR DE LA IMAGEN DE ENTRADA MEDIANTE LOS PARAMETROS DE TRANSFORMACION, Y (E) UN MEDIO DE TRANSMISION, PARA TRANSMITIR LA IMAGEN COMPRIMIDA Y LOS DATOS DE LAS COORDENADAS.
