Algorithm implementation for iris identification

Abstract

This paper presents an architecture dedicated to iris identification based on wavelet packet analysis and its implementation on SoPC. The identification algorithm starts with iris capture, localization and unwrapping. Then a signature is extracted thanks to wavelet packet decomposition. Two packets are enough for signature encoding. Finally, the signature is compared to a database for matching. The complete algorithm is implemented on a SoPC which is composed by a NIOS processor and some hardware IP.
