Abstract
LA INVENCION SE REFIERE A UN METODO PARA LA COMPRESION Y DESCOMPRESION DE IMAGENES DE PRUEBA BINARIAS. EL METODO DISTINGUE ENTRE AREAS GRANDES DE BAJA FRECUENCIA Y AREAS PEQUEÑAS DE ALTA FRECUENCIA EN EL CUADRO ORIGINAL. PARA LAS AREAS DE BAJA FRECUENCIA, SE USA UN ESQUEMA PARA COMPRESION DISIPATIVA, MIENTRAS QUE PARA LAS AREAS DE ALTA FRECUENCIA SE APLICA UN ESQUEMA QUE PERMITE COMPRESION SIN PERDIDAS. EL PROCEDIMIENTO DE COMPRESION Y DESCOMPRESION IMPLICA LAS SIGUIENTES CINCO ETAPAS: 1.PREFILTRADO PARA EXTRAER TODOS LOS PARCHES NEGROS (POR EJEMPLO, MEDIANTE LA ELIMINACION DE PIXEL NEGROS, EXCEPTO DONDE ELLOS PERTENECEN A UN SEGMENTO GRANDE NEGRO; 2.EVALUACION RAPIDA DE COMPRESIBILIDAD, MEDIANTE LA DIVISION DE IMAGENES EN SEGMENTOS MUTUAMENTE EXCLUSIVOS, Y APLICANDO DIFERENTES MODOS DE COMPRESION A CADA SEGMENTO; 3.SUBMUESTREO ORIENTADO A LA CONECTIVIDAD, PARA REDUCIR LA RESOLUCION EN LAS DIRECCIONES HORIZONTAL Y VERTICAL. LA IMAGEN SE SEGMENTA EN BLOQUES Y SE DETERMINA UNA REPRESENTACIONDE 1 PIXEL PARA CADA BLOQUE; 4.COMPRESION SIN PERDIDAS Y DESCOMPRESION DONDE EL FICHERO REDUCIDO SE COMPRIME POR TECNICAS CONVENCIONALES; 5.RECONSTRUCCION MEDIANTE INVERSION DE SECUENCIA. LA DESCOMPRESION SIN PERDIDAS RECUPERARA EL FICHERO SUBMUESTREADO, EXPANSION DEL FICHERO SUBMUESTREADO A TRAVES DE LA SUSTITUCION DE CADA PIXEL POR UN BLOQUE QUE TENGA IGUAL VALOR, POSFILTRACION.
