Sommario/riassunto

This book provides the new results in wavelet filter banks based feature extraction, and the classifier in the field of iris image recognition. It provides the broad treatment on the design of separable, non-separable wavelets filter banks, and the classifier. The design techniques presented in the book are applied on iris image analysis for person authentication. This book also brings together the three strands of research (wavelets, iris image analysis, and classifier). It compares the performance of the presented techniques with state-of-the-art available schemes. This book contains the compilation of basic material on the design of wavelets that avoids reading many different books. Therefore, it provide an easier path for the new-comers, researchers to



master the contents. In addition, the designed filter banks and classifier can also be effectively used than existing filter-banks in many signal processing applications like pattern classification, data-compression, watermarking, denoising etc.  that will give the new directions of the research in the relevant field for the readers.

Sommario/riassunto

Modern molecular biology and genetics has enabled significant strides in research on the basic properties of biological rhythms. These advances will, in addition to relevance for understanding of cell and body biochemistry, health, and aging, provide insights into the molecular control of behavior. This comprehensive account of the molecular basis of circadian rhythms will cover the recent advances in addition to providing a solid groundwork in the basic aspects of biological timing.
