Abstract
CUANDO BLOQUES TRANSFORMADOS Y CUANTIFICADOS DE DATOS DE DIBUJO ESTAN CODIFICADOS, UN BLOQUE ESTANDO CONSTITUIDO POR UNA MATRIZ DE COEFICIENTES, LOS EVENTOS DENTRO DE CADA BLOQUE QUE VA A SER CODIFICADO COMPRENDEN PRIMERAMENTE UN MARCADOR QUE INDICA EL NUMERO DE COEFICIENTES-CERO EN EL BLOQUE ENTRE UN COEFICIENTE ACTUAL NO-CERO Y EL COEFICIENTE NO-CERO PREVIO Y, EN SEGUNDO LUGAR, EL TAMAÑO DEL COEFICIENTE ACTUAL NO-CERO DEL BLOQUE. CADA EVENTO ESTA, DE ACUERDO CON LA INVENCION, COMPLETO AÑADIENDO UN TERCER PARAMETRO QUE INDICA SI EL COEFICIENTE ACTUAL NO-CERO ES EL ULTIMO COEFICIENTE NO-CERO DEL BLOQUE. ASI PUES, CADA EVENTO ESTA REPRESENTADO COMO UNA CANTIDAD TRIDIMENSIONAL.
