Abstract

SE REVELA UN METODO Y UN DISPOSITIVO PARA CODIFICAR UNA SEÑAL DE VIDEO. EL DECODIFICADOR DE VIDEO, POR EJEMPLO, UN CODIFICADOR MPEG (2), PRODUCE UNA IMAGEN DE PREDICCION CON MOVIMIENTO COMPENSADO (PRED). ANTES DE LA CODIFICACION, DICHA IMAGEN DE PREDICCION CON MOVIMIENTO COMPENSADO, SE COMBINA (1) CON LA IMAGEN DE ENTRADA QUE CAUSA EFECTIVAMENTE, A LA VEZ, EL RUIDO EN LA IMAGEN DE ENTRADA Y EL RUIDO DE CUANTIFICACION. LA CANTIDAD DE REDUCCION DEL RUIDO SE CONTROLA (15), PREFERIBLEMENTE, COMO RESPUESTA AL MISMO PARAMETRO (MAD) QUE USA EL ESTIMADOR DEL MOVIMIENTO (29) PARA BUSCAR EL BLOQUE DE PIXELES MAS PARECIDO, DENTRO DE LA MEMORIA DE PREDICCION (28).
