Abstract

LA INVENCION PROPORCIONA UNA FORMA DE REALIZAR INTERPOLACION MEJORADA CON MOVIMIENTO COMPENSADO DE IMAGENES EN MOVIMIENTO, COMO LA TELEVISION, UTILIZANDO VECTORES DE MOVIMIENTO DE FIABILIDAD VARIABLE. TENIENDO EN CUENTA LA FIABILIDAD DE LOS VECTORES DE MOVIMIENTO, PRODUCIDOS POR UN DISPOSITIVO DE ESTIMACION DEL MOVIMIENTO INDEPENDIENTE, PUEDE PRODUCIRSE UNA INTERPOLACION SUBJETIVAMENTE AGRADABLE. ESTO CONTRASTA CON LA INTERPOLACION DE MOVIMIENTO COMPENSADO SIMPLE, SIN TENER EN CUENTA LA FIABILIDAD DEL VECTOR DE MOVIMIENTO, QUE CON FRECUENCIA SE DEGRADA POR MEDIO DE LOS ARTEFACTOS DE CONMUTACION INACEPTABLES DEBIDOS A VECTORES DE MOVIMIENTO NO FIABLES. LA INVENCION PUEDE USARSE, POR EJEMPLO, PARA MEJORAR EL RENDIMIENTO DE LOS CONVERTIDORES DE NORMAS CON MOVIMIENTO COMPENSADO UTILIZADOS PARA CONVERTIR ENTRE NORMAS DE TELEVISION CON DIFERENTES VELOCIDADES DE IMAGENES. LA INVENCION PERMITE UNA TRANSICION GRADUAL ENTRE EL MOVIMIENTO COMPENSADO Y LA INTERPOLACION COMPENSADA SIN MOVIMIENTO DEPENDIENDO DE LA FIABILIDAD DEL VECTOR DE MOVIMIENTO UTILIZADO. ESTO SE CONSIGUE MODIFICANDO LA TEMPORIZACION DE INTERPOLACION TEMPORAL, UTILIZANDO UNA TABLA DE CONSULTA CONTROLADA POR UNA SEÑAL DE FIABILIDAD DE VECTOR PRODUCIDA POR EL ESTIMADOR DE MOVIMIENTO. EFECTIVAMENTE, ESTO ADAPTA LA TRAYECTORIA DE MOVIMIENTO DE LAS IMAGENES DE SALIDA INTERPOLADAS.
