Abstract :
The impact of using different lossless compression algorithms when compressing biometric iris sample data from several public iris databases is investigated. In particular, we relate the application of dedicated lossless image codecs like JPEG-LS, CALIC, and PNG, lossless variants of lossy codecs like JPEG2000 and JPEG XR, and two general purpose compression schemes to rectilinear iris sample imagery from seven public databases. The application of additional prediction as a preprocessing strategy as well as a conversion to a set of binary images to enable JBIG application is evaluated. The results are discussed in the light of the recent ISO/IEC FDIS 19794-6 and ANSI/NIST-ITL 1-2011 standards and IREX recommendations.
