Iris recognition with image compression using SPIHT
Archana J. Gawad, Shoba Krishnan · 2010
Iris recognition is used to identify people. A biometric system provides automatic identification of an individual based on a unique feature or characteristic possessed by the individual. Commercial iris recognition systems are used, to allow access to secure areas, and for secure access to computer networks. With the growing employment of iris recognition systems and associated research to support this, the need for large databases of iris images is growing. If required storage space is not adequate for these images, compression is an alternative. It allows a reduction in the space needed to store these iris images, although it may be at a cost in some amount of information lost in the process. This paper investigates the effects of image compression on iris recognition. Compression is performed using SPIHT, and the iris recognition algorithm used is based on several methods.
