Abstract

SE DESCRIBE UN PROCEDIMIENTO PARA LA DISOCIACION DE SEGMENTOS MOVIDOS EN GRUPO, QUE DE MODO MULTIPLE REPRESENTAN MUTUAMENTE UN OBJETO MOVIDO DE FORMA OCULATA EN UNA SECUENCIA DE VIDEO. EN UNA PRIMERA ETAPA SE DETECTAN LOS SEGMENTOS MOVIDOS EN GRUPO, CONN LOS QUE SE COLOCAN RECTANGULOS CIRCUNSCRITOS ALREDEDOR DE LOS SEGMENTOS MOVIDOS EN GRUPO DE UNA IMAGEN DE VIDEO. EL TAMAÑO DE ESTE RECTANGULO QUE CIRCUNSCRIBE SE COMPARA CON UN LIMITE SUPERIOR DADO PREVIAMENTE Y SE MUEVE CON EL SEGMENTO EN EL GRUPO CORRESPONDIENTE, CUYO RECTANGULO QUE LO CIRCUNSCRIBE ES MAYOR QUE EL LIMITE SUPERIOR DADO EFECTUADO COMO SEGMENTOS RECONOCIBLE MOVIDOS EN GRUPO. EN CADA UNO DE ESTOS GRUPOS SE BUSCA EN UNA SEGUNDA ETAPA UN CANTO HORIZONTAL DE CONDUCCION, QUE NO ESTA DISPUESTO AUN EN NINGUN RECTANGULO QUE LO CIRCUNSCRIBE. CADA UNO DE ESTOS CANTOS ESTA DISPUESTO EN EL RECTANGULO QUE LO CIRCUNSCRIBE, Y TIENEN LA AMPLITUD DE ESTE CANTO Y SIENDO SU ALTURA DADA A TRAVES DE LA ALTURA MEDIA DE TODOS LOS OBJETOS DE LA CLASE DE OBJETOS RESPECTIVOS A PARTIR DE UNA CANTIDAD DADA PREVIAMENTE DE LAS CLASES DE OBJETOS, Y CUYOS OBJETOS POSEEN UNA AMPLITUD MEDIA, QUE SE ENCUENTRA PROXIMA A LA AMPLITUD DEL CANTO.
