The iris is a circular, pigmented tissue that separates the anterior chamber of the eye from the posterior chamber. It has a crucial role on controlling the amount of the light entering the eye through its central opening “the pupil". The Iris has multiple important functions that support and provide image clarity on the retina. However, it is a largely neglected part of the eye, compared to the cornea lens, retina, and optic nerve, and has not been focused on in a comprehensive way until now. The Iris: Understanding the Essentials, combines different aspects of scientific information from a variety of fields, such as anatomy, histopathology, molecular biology, electron microscopy and other diagnostic modalities. Each chapter will include pearls and summary points, and this multi-disciplinary approach helps the clinician diagnose and treat the large variety of diseases that affect the iris, with the main emphasize on pigmentary pathological changes that can affect the color of the eye. Written as a reference review book for universities, practicing ophthalmologists, Ophthalmology residents, pharmaceutical companies and diagnostic equipment manufacturing companies this book summarizes the information in an easy-to-use manner to help the reader better understand the iris, iris structure, physiology and function.

Iris Origo was one of the twentieth century's most attractive and intriguing women, a brilliantly perceptive historian and biographer whose works remain widely admired. Iris grew up in Italy where she became part of the colourful and privileged Anglo-Florentine set that included Edith Wharton, Harold Acton and the Berensons. When Iris married Antonio Origo, they bought and revived La Foce, a derelict stretch of the beautiful Val d'Orcia valley in Tuscany and created an estate that thrives to this day. During World War II they sided firmly with the Allies, taking considerable risks in protecting children and sheltering partisans and Iris's diary from that time, War in Val d'Orcia, is now considered a modern classic. Caroline Moorehead has drawn on many previously unpublished letters, diaries, and papers to write the definitive biography of a very remarkable woman.

Iris recognition is one of the highest accuracy techniques used in biometric systems. The accuracy of the iris recognition system is measured by False Reject Rate (FRR), which measures the authenticity of a user who is incorrectly rejected by the system due to changes in iris features (such as aging and health condition) and external factors that affect iris image, for instance, high noise rate. External factors such as technical fault, occlusion, and source of lighting that causes the image acquisition to produce distorted iris images create error, hence are incorrectly rejected by the biometric system. FRR can be reduced using wavelets and Gabor filters, cascaded classifiers, ordinal measures, multiple biometric modalities, and a selection of unique iris features. Nonetheless, in the long duration of the matching process, existing methods were unable to identify the authenticity of the user since the iris structure itself produces a template changed due to aging. In fact, the iris consists of unique features such as crypts, furrows, collarette, pigment blotches, freckles, and pupils that are distinguishable among humans. Earlier research was done by selecting unique iris features. However, these had low accuracy levels. A new way of identifying and matching the iris template using the nature-inspired algorithm is described in this book. It provides an overview of iris recognition that is based on nature-inspired environment technology. The book is useful for students from universities, polytechnics, community colleges; practitioners; and industry practitioners.
