Abstract

Se describen las tecnicas de inscripcion y verificacion biometrica para las regiones ocular-vascular, periocular y facial. Las regiones de imagen perioculares se pueden definir con base en las dimensiones de una region ocular identificada en una imagen de una region facial. Los descriptores de caracteristicas se pueden generar para puntos de interes en las regiones ocular y periocular usando una combinacion de descriptores de caracteristicas de histograma de patrones. Las metricas de calidad para las regiones se pueden determinar en funcion de los puntajes del valor de region calculados con base en la textura que rodea los puntos de interes. Un proceso de correspondencia biometrica para el calculo de un puntaje de coincidencia basado en las regiones ocular y periocular puede progresivamente incluir regiones perioculares adicionales para obtener una mayor confianza de coincidencia.
