This book reviews different methods used for iris recognition system. Special emphasis is given to most difficult step in iris biometrics system i.e. iris segmentation. Different methods for four different available databases have been given in detail. Figures will give readers a complete understanding of the concept. Further more, instead of phase, identification is based on bit-plane slicing of the normalized iris.

Colored digital images are extensively used in computer applications. Uncompressed digital images require considerable storage capacity and transmission bandwidth. Efficient image compression solutions are becoming more critical with the recent growth of data intensive, multimedia-based web applications. This book studies color image compression with discrete Cosine, Fourier and Wavelets (Haar and Daubechies) transforms. As a necessary background, the basic concepts of color images, Wavelets and recently used compression algorithms are discussed. In the end, comparison of different...
