• Sommario/riassunto: This volume provides an overview of the latest research findings on the physics, physiology, and psychology of food oral consumption, as well as the experimental techniques available for food oral studies. Coverage includes the main physical and physiological functionalities of the mouth; the location and functionalities of various oral receptors; the main sequences of eating and drinking, and the concomitant food disintegration and destabilisation. Chapters also explain oral processing and its relation to flavour release and texture perception, and there is an introduction to the principles o

• Sommario/riassunto: This book discusses anti-spoofing techniques in detail. For each anti-spoofing technology, different experimental configurations, processing strategies, scope for generalization, advantages and limitations are detailed. The book also considers applicability of artificial intelligence techniques for automated biometric spoof detection, and future scope of research in this direction.
