Abstract

UN PROCEDIMIENTO PARA DETECCION Y SEGUIMIENTO DE OBJETOS MOVILES EN SERIE DE IMAGENES DIGITALES CON FONDO INMOVIL POR COMPARACION DE LA SERIE DE IMAGENES CON UNA SERIE DE IMAGENES DE FONDO CALCULADA, EN QUE SE CALCULA UNA SERIE DE SILUETAS DE OBJETOS BINARIOS CUYOS SEGMENTOS TRANSMITEN LAS FORMAS Y POSICIONES DEL OBJETO MOVIL, DONDE POR EL ENCUENTRO DE ESTOS SEGMENTOS SE TRANSMITEN LOS VECTORES DE MOVIMIENTO DEL OBJETO MOVIL. ADEMAS SE CALCULA UNA SERIE DE IMAGENES DE FONDO POR PARTICIPACION RECURSIVA ESPACIAL SELECTIVA Y TEMPORAL DE LA SERIE DE IMAGENES DE ENTRADA, EN QUE NO SE CONTIENEN LOS OBJETOS MOVILES AUNQUE SE CONTIENEN OTRAS VARIACIONES DEL FONDO QUE NO SE ORIGINAN POR OBJETOS MOVILES. ADEMAS SE CALCULA UNA SERIE DE SILUETAS DE OBJETOS BINARIOS POR BINARIZACION DE LA SERIE DE IMAGENES DE DIFERENCIA DE LA SERIE DE IMAGENES DE ENTRADA Y DE LA SERIE DE IMAGENES DE FONDO CON AYUDA DE UNA ESCALA CUYO VALOR SE UTILIZA PARA MANDO DE LA SELECTIVIDAD ESPACIAL EN EL CALCULO DE LA SERIE DE IMAGENES DE FONDO Y CUYOS SEGMENTOS SE DETERMINAN CONJUNTAMENTE CON SU TAMAÑO Y SITUACION DEL PUNTO DE GRAVEDAD. SEGUIDAMENTE SE PARTICIPAN VECTORES DE MOVIMIENTO DEL OBJETO DETECTADO POR MINIMACION DE LOS SEGMENTOS DE SILUETAS TRASLADADOS POR LA CANTIDAD DE SEGMENTOS Y SE DETERMINA LA DIFERENCIA DE VALOR GRIS, DONDE SE UTILIZAN LAS DIFERENCIAS DE LOS SEGMENTOS CORRESPONDIENTES A LOS VECTORES DEL PUNTO DE GRAVEDAD COMO VECTORES DE PARTIDA EN LA MINIMIZACION.
