Presenting encryption algorithms with diverse characteristics, Image Encryption: A Communication Perspective examines image encryption algorithms for the purpose of secure wireless communication. It considers two directions for image encryption: permutation-based approaches and substitution-based approaches. Covering the spectrum of image encryption principles and techniques, the book compares image encryption with permutation- and diffusion-based approaches. It explores number theory-based encryption algorithms such as the Data Encryption Standard, the Advanced Encryption Standard, and the RC6 algorithms. It not only details the strength of various encryption algorithms, but also describes their ability to work within the limitations of wireless communication systems. Since some ciphers were not designed for image encryption, the book explains how to modify these ciphers to work for image encryption. It also provides instruction on how to search for other approaches suitable for this task. To make this work comprehensive, the authors explore communication concepts concentrating on the orthogonal frequency division multiplexing (OFDM) system and present a simplified model for the OFDM communication system with its different implementations. Complete with simulation experiments and MATLAB (R) codes for most of the simulation experiments, this book will help you gain the understanding required to select the encryption method that best fulfills your application requirements.

In the last few years, biometric techniques have proven their ability to provide secure access to shared resources in various domains. Furthermore, software agents and multi-agent systems (MAS) have shown their efficiency in resolving critical network problems. Iris Biometric Model for Secured Network Access proposes a new model, the IrisCryptoAgentSystem (ICAS), which is based on a biometric method for authentication using the iris of the eyes and an asymmetric cryptography method using "Rivest-Shamir-Adleman" (RSA) in an agent-based architecture. It focuses on the development of new methods in biometric authentication in order to provide greater efficiency in the ICAS model. It also covers the pretopological aspects in the development of the indexed hierarchy to classify DRVA iris templates. The book introduces biometric systems, cryptography, and multi-agent systems (MAS) and explains how they can be used to solve security problems in complex systems. Examining the growing interest to exploit MAS across a range of fields through the integration of various features of agents, it also explains how the intersection of biometric systems, cryptography, and MAS can apply to iris recognition for secure network access. The book presents the various conventional methods for the localization of external and internal edges of the iris of the eye based on five simulations and details the effectiveness of each. It also improves upon existing methods for the localization of the external and internal edges of the iris and for removing the intrusive effects of the eyelids.

Fuzzy sets, near sets, and rough sets are useful and important stepping stones in a variety of approaches to image analysis. These three types of sets and their various hybridizations provide powerful frameworks for image analysis. Emphasizing the utility of fuzzy, near, and rough sets in image analysis, Rough Fuzzy Image Analysis: Foundations and Methodologies introduces the fundamentals and applications in the state of the art of rough fuzzy image analysis. In the first chapter, the distinguished editors explain how fuzzy, near, and rough sets provide the basis for the stages of pictorial pattern recognition: image transformation, feature extraction, and classification. The text then discusses hybrid approaches that combine fuzzy sets and rough sets in image analysis, illustrates how to perform image analysis using only rough sets, and describes tolerance spaces and a perceptual systems approach to image analysis. It also presents a free, downloadable implementation of near sets using the Near Set Evaluation and Recognition (NEAR) system, which visualizes concepts from near set theory. In addition, the book covers an array of applications, particularly in medical imaging involving breast cancer diagnosis, laryngeal pathology diagnosis, and brain MR segmentation. Edited by two leading researchers and with contributions from some of the best in the field, this volume fully reflects the diversity and richness of rough fuzzy image analysis. It deftly examines the underlying set theories as well as the diverse methods and applications.

Action Analysis is one of the fundamental princples of animation that underpins all types of animation: 2d, 3d, computer animation, stop motion, etc. This is a fundamental skill that all animators need to create polished, believable animation. An example of Action Analysis would be Shrek's swagger in the film, Shrek. The animators clearly understood (through action analysis) the type of walk achieved by a large and heavy individual (the real) and then applied their observations to the animated character of an ogre (the fantastic). It is action analysis that enabled the animation team to visually translate a real life situation into an ogre's walk, achieving such fantastic results.Key animation skills are demonstrated with in-depth illustrations, photographs and live action footage filmed with high speed cameras. Detailed Case Studies and practical assignments ground action analysis methodology with real life examples. Action Analysis for Animators is a essential guide for students, amateurs and professionals.

While the earliest character representations in video games were rudimentary in terms of their presentation and performance, the virtual characters that appear in games today can be extremely complex and lifelike. These are characters that have the potential to make a powerful and emotional connection with gamers. As virtual characters become more intricate and varied, there is a growing need to examine the theory and practice of virtual character design. This book seeks to develop a series of critical frameworks to support the analysis and design of virtual characters. Virtual Character Design for Games and Interactive Media covers a breadth of topics to establish a relationship between pertinent artistic and scientific theories and good character design practice. Targeted at students, researchers, and professionals, the book aims to show how both character presentation and character performance can be enhanced through careful consideration of underlying theory. The book begins with a focus on virtual character presentation, underpinned by a discussion of biological, artistic, and sociological principles. Next it looks at the performance of virtual characters, encompassing the psychology of emotion and personality, narrative and game design theories, animation, and acting. The book concludes with a series of applied virtual character design examples. These examples examine the aesthetics of player characters, the design and performance of the wider cast of game characters, and the performance of characters within complex, hyperreal worlds.
