The book presents three most significant areas in Biometrics and Pattern
Recognition. A step-by-step approach for design and implementation of
Dual Tree Complex Wavelet Transform (DTCWT) plus Rotated Complex Wavelet
Filters (RCWF) is discussed in detail. In addition to the above, the
book provides detailed analysis of iris images and two methods of iris
segmentation. It also discusses simplified study of some subspace-based
methods and distance measures for iris recognition backed by empirical
studies and statistical success verifications.
