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.
