Abstract

En un sistema para determinar la vitalidad de una imagen presentada para la autenticacion, una senal de referencia se representa en una pantalla, y una reflexion de la senal representada de un objetivo se analiza para determinar su vitalidad. El analisis incluye filtrar paso banda espacial y/o temporalmente la senal reflejada, y determinar los valores RGB para cada fotograma en la senal reflejada y/o cada pixel en uno o mas fotogramas de la senal reflejada. El nivel de fotograma y/o correlaciones pixel por pixel entre los valores RGB determinados y la senal representada se procesan por computadora, y se hace una determinacion si una imagen presentada es en vivo o falsa usando una o ambas correlaciones.
