Abstract
ESTA INVENCION SE REFIERE A LA CODIFICACION DE VIDEO CON COMPENSACION DEL MOVIMIENTO (MC) Y A UN SISTEMA DE PREDICCION DE MC QUE PERMITE LA CODIFICACION RAPIDA Y COMPACTA DE CAMPOS DE VECTORES DE MOVIMIENTO, MANTENIENDO AL MISMO TIEMPO UN ERROR DE PREDICCION MUY BAJO. REDUCIENDO LOS ERRORES DE PREDICCION Y EL NUMERO DE BITS NECESARIOS PARA LA REPRESENTACION DEL CAMPO VECTORIAL DEL MOVIMIENTO, SE CONSIGUEN IMPORTANTES AHORROS DE BITRATO. LA REDUCCION DEL BITRATO NECESARIO PARA REPRESENTAR EL CAMPO DE MOVIMIENTO SE CONSIGUE MEDIANTE LA FUSION DE SEGMENTOS EN TRAMAS DE VIDEO, MEDIANTE LA ADAPTACION DEL MODELO DE CAMPO DE MOVIMIENTO Y MEDIANTE LA UTILIZACION DE MODELO DE CAMPO DE MOVIMIENTO SOBRE LA BASE DE POLINOMIOS ORTOGONALES.
