Abstract

En la presente se describen sistemas y métodos para localizar un objeto detectado en un video. El sistema detecta una cada delimitadora al menos parcialmente alrededor de un objeto en un primer cuadro en un primer momento en el video y un segundo cuadro en el video correspondiente a un segundo momento. El sistema determina si no hay movimiento dentro de la cada delimitadora del segundo cuadro. El sistema compara información de los bordes, o información de color o información de intensidad asociada con uno o más píxeles en el primer cuadro con información de los bordes, o información de color o información de intensidad asociada con uno o más píxeles dentro de la cada delimitadora. El sistema genera un puntaje de acuerdo con la comparación. El sistema además determina en función del puntaje si el objeto está presente en el segundo cuadro. El sistema también determina un período de tiempo estimado de una primera aparición del objeto.
