The book "Iris Analysis for Biometric Recognition Systems" offers a comprehensive examination of the most significant areas in biometrics and pattern recognition. It thoroughly discusses the steps for designing and implementing the Dual Tree Complex Wavelet Transform (DTCWT) as well as the Rotated Complex Wavelet Filters (RCWF). Additionally, an in-depth analysis of iris images is presented, including two methods for iris segmentation. The work also provides a simplified overview of some subspace-based methods and distance measures for iris recognition, supported by empirical studies and statistical success checks.
