Abstract

UN APARATO DE CODIFICACION DE IMAGEN COMPRENDE UNA UNIDAD DCT PARA TRANSFORMAR UNA SEÑAL DE IMAGEN CORRESPONDIENTE A UN BLOQUE OBJETIVO QUE ESTA SIENDO PROCESADO EN COMPONENTES DE FRECUENCIA, UN CUANTIFICADOR PARA CUANTIFICAR LA SALIDA DE LA UNIDAD DCT PARA GENERAR COEFICIENTES DE TRANSFORMACION, UN GENERADOR DE COEFICIENTE DIFERENCIAL PARA GENERAR COEFICIENTES DIFERENCIALES QUE SON DIFERENCIAS ENTRE LOS COEFICIENTES DE TRANSFORMACION DEL BLOQUE OBJETIVO Y LOS COEFICIENTES DE PREDICCION PARA EL BLOQUE OBJETIVO, Y UN CIRCUITO DE IDENTIFICACION PARA IDENTIFICAR SI LOS VALORES DE LOS COEFICIENTES DIFERENCIALES ESTAN O NO DENTRO DE UN RANGO DE VALORES NUMERICOS QUE PUEDEN SER EXPRESADOS POR CODIGOS DE N BITS DE LONGITUD FIJA. CUANDO LOS VALORES DE LOS COEFICIENTES DIFERENCIALES ESTAN DENTRO DEL RANGO, ESTOS COEFICIENTES DIFERENCIALES SON CODIFICADOS. CUANDO AL MENOS UNO DE LOS VALORES DE LOS COEFICIENTES DIFERENCIALES ESTA FUERA DEL RANGO, LOS COEFICIENTES DE TRANSFORMACION DEL BLOQUE OBJETIVOSON CODIFICADOS. EN CONSECUENCIA, CUANDO LOS COEFICIENTES DE TRANSFORMACION, QUE HAN SIDO OBTENIDOS POR LA TRANSFORMACION DE FORMA COMPRESIVA DE LA SEÑAL DE IMAGEN, SON CODIFICADOS UTILIZANDO PALABRAS DE CODIGO PREDETERMINADAS, LA CODIFICACION PREDICTIVA INTRATRAMA DE ESTOS COEFICIENTES DE TRANSFORMACION PUEDE SER LLEVADA A CABO DE FORMA REVERSIBLE, SIN DEGRADAR LA EFICIENCIA DE LA CODIFICACION.
