Abstract

LA INVENCION SE REFIERE A UN PROCEDIMIENTO DE CALCULO DE UNA LLAVE KD DE CORTE DE UN SUJETO QUE EVOLUCIONA DELANTE DE UN FONDO COLOREADO, PERMITIENDO DICHA LLAVE SEPARAR EL ESPACIO DE LOS COLORES EN TRES ZONAS, UNA PRIMERA ZONA (1) QUE DEFINE UN VOLUMEN QUE REPRESENTA EL FONDO COLOREADO, UNA SEGUNDA ZONA (3) QUE DEFINE UN VOLUMEN QUE REPRESENTA EL SUJETO Y UNA TERCER ZONA (2) QUE DEFINE UNA ZONA DE TRANSICION ENTRE EL FONDO COLOREADO Y EL SUJETO, CARACTERIZADO PORQUE COMPRENDE DIFERENTES ETAPAS DE CALCULO (10, 11, 12, 13, 14, 15) QUE PERMITEN DEFINIR EL VOLUMEN QUE REPRESENTA EL FONDO COLOREADO EN FORMA DE CONO CON ANGULO DE ABERTURA {AL} CUYO EJE DE SIMETRIA (W) PASA POR EL PUNTO ACRONO Y DE LUMINOSIDAD NULA DEL ESPACIO DE LOS COLORES Y UN PUNTO QUE REPRESENTA EL COLOR DEL FONDO COLOREADO. LA INVENCION SE REFIERE TAMBIEN A CUALQUIER TIPO DE APARATO ELECTRONICO QUE EMPLEA EL PROCEDIMIENTO MENCIONADO ARRIBA, TAL COMO LOS MEZCLADORES DE VIDEO O TAMBIEN LOS DISPOSITIVO AUTONOMOS DE CORTE Y DEINCRUSTACION DE IMAGENES DE VIDEO.
