Abstract

SE DESCRIBE UNA TECNICA PARA DERIVAR UNA IMAGEN COMPUESTA DE VIDEO FUSIONANDO DATOS DE IMAGENES DE VIDEO DE PRIMERA LINEA Y DE FONDO, SUMINISTRADAS DESDE UNA PLURALIDAD DE FUENTES DE SEÑALES DE VIDEO SEPARADAS EMPLEANDO LA INSERCION DE CLAVES DE MODELO MAS BIEN QUE LA INSERCION DE CLAVES DE COLOR DE LA TECNICA ANTERIOR PARA TAL FIN. LA INSERCION DE CLAVE DE MODELO IMPLICA LA SUSTITUCION DE UN PRIMER MODELO (202) EN UNA PERSPECTIVA DE VIDEO (204A) CON UN SEGUNDO MODELO (204B). ESTO SE LLEVA A CABO DETECTANDO PRIMERO EL PRIMER MODELO (202) EN LA PERSPECTIVA DEL VIDEO Y CALCULANDO LA COLOCACION DE ESTE PRIMER MODELO DETECTADO CON RESPECTO A UN OBJETO DE REFERENCIA EN LA PERSPECTIVA DEL VIDEO. EL SEGUNDO MODELO SE TRANSFORMA A CONTINUACION EN SU CONFIGURACION USANDO EL CALCULO DE POSICION DEL PRIMER MODELO DETECTADO. POR ULTIMO, SE SUSTITUYE EL PRIMER MODELO DETECTADO POR EL SEGUNDO MODELO TRANSFORMADO EN SU CONFIGURACION.
