Abstract

Amaç, biyometrik görüntüleme sırasında dış ışık içerisinde varyasyon mevcut olsa dahi, yüksek hassasiyetli kimlik doğrulamanın elde edilmesidir. Bir biyometrik kimlik doğrulama cihazı, sırasıyla, bir canlı vücut kısmının görüntülerini yaklayan bir görüntü yakalama ünitesini, canlı vücut kısmının görüntülerinin yakalanması için bir ışık kaynağını (3), dalga boyuna bağlı olarak seçici olarak ışığı geçiren veya bloke eden bir optik filtreyi, aynı anda yakalanan birden fazla dalga boyunu ayıran bir spektroskopik işlem ünitesini (23) ve yakalanan görüntüler içerisinde canlı vücut kısmının önceden belirlenmiş bir kısmının şeklini ve duruşunu hesaplayan bir hesaplama ünitesini içerir. Hesaplama ünitesi, canlı vücut kısmının önceden belirlenmiş bir kısmının şeklini ve duruşunu hesaplar, arka plan uzaklaştırma ünitesi (24), canlı vücut kısmının spektral görüntüsünü (243) ve istenmeyen çevre ışığının (142) spektral görüntüsünü (243) kullanarak canlı vücut kısmının görüntüsünden arka planı uzaklaştırır ve kimlik doğrulama işlem ünitesi (21), önceden belirlenmiş kısmın görüntüsünü kullanarak biyometrik kimlik doğrulama işlemini gerçekleştirir.
