Perception of Pixelated Images covers the increasing use of these images in everyday life as communication, socialization, and commerce increasingly rely on technology. The literature in this book is dispersed across a wide group of disciplines, from perception and psychology to neuroscience, computer science, engineering, and consumer science. The book summarizes the research to date, answering such questions as, What are the spatial and temporal limits of perceptual discrimination of pixelated images?, What are the optimal conditions for maximizing information extracted from pixelated images?, and How does the method of pixelation compromise or assist perception? Integrates research from psychology, neuroscience, computer science, and engineering Explains how the process of perception works for pixelated images Identifies what assists and hinders perception, including the method of pixelation Discusses the limits of perception of pixelated images

Visual masking is a technique used in cognitive research to understand pre-conscious processes (priming, for example), consciousness, visual limits, and perception issues associated with psychopathology. This book is a short format review of research using visual masking: how it has been used, and what these experiments have discovered.Topics covered include concepts, varieties, and theories of masking; masking and microgenetic mechanisms and stagesof visual processing; psychopharmacological and genetic factors in masking, and more. Provides succinct information about the widely dispersed masking studies and points out some new trends in masking research Reviews transcranial magnetic stimulation (TMS) as an alternative to the traditional psychophysical masking methods Comments on the methodological pitfalls hidden in the practice of masking, helping to improve the quality of future research where masking is used as a tool Informs readers about recent developments in theoretical attempts to understand masking

Our contact with the world is through perception, and therefore the study of the process is of obvious importance and signi?cance. For much of its long history, the study of perception has been con?ned to natural- tic observation. Nonetheless, the phenomena considered worthy of note have not been those that nurture our survival—the veridical features of perception—but the oddities or departures from the common and c- monplace accuracies of perception. With the move from the natural world to the laboratory the oddities of perception multiplied, and they received ever more detailed scrutiny. My general intention is to examine the interpretations of the perc- tual process and its errors throughout history. The emphasis on errors of perception might appear to be a narrow approach, but in fact it enc- passes virtually all perceptual research from the ancients until the present. The constancies of perception have been taken for granted whereas - partures from constancies (errors or illusions) have fostered fascination.

WITH TODAY’S DIGITAL TECHNOLOGY, the image is no longer a stable representation of the world, but a programmable view of a database that is updated in real time. It no longer functions as a political and iconic representation, but plays a vital role in synchronic data-todata relationships. It is not only part of a programme, but it contains its own ‘operating code’: it is a programme in itself. Softimage aims to account for that new reality, taking readers on a journey that gradually undoes our unthinking reliance on the apparent solidity of the photographic image and building in its place an original and timely theorization of the digital image in all its complexity, one that promises to spark debate within the evolving fields of image studies and software studies.

A complete introduction to the basic and intermediate concepts of image processing from the leading people in the field Up-to-date content, including statistical modeling of natural, anistropic diffusion, image quality and the latest developments in JPEG 2000 This comprehensive and state-of-the art approach to image processing gives engineers and students a thorough introduction, and includes full coverage of key applications: image watermarking, fingerprint recognition, face recognition and iris recognition and medical imaging. "This book combines basic image processing techniques with some of the most advanced procedures. Introductory chapters dedicated to general principles are presented alongside detailed application-orientated ones. As a result it is suitably adapted for different classes of readers, ranging from Master to PhD students and beyond." – Prof. Jean-Philippe Thiran, EPFL, Lausanne, Switzerland "Al Bovik’s compendium proceeds systematically from fundamentals to today’s research frontiers. Professor Bovik, himself a highly respected leader in the field, has invited an all-star team of contributors. Students, researchers, and practitioners of image processing alike should benefit from the Essential Guide." – Prof. Bernd Girod, Stanford University, USA "This book is informative, easy to read with plenty of examples, and allows great flexibility in tailoring a course on image processing or analysis." – Prof. Pamela Cosman, University of California, San Diego, USA A complete and modern introduction to the basic and intermediate concepts of image processing – edited and written by the leading people in the field An essential reference for all types of engineers working on image processing applications Up-to-date content, including statistical modelling of natural, anisotropic diffusion, image quality and the latest developments in JPEG 2000

Ecomedia: Key Issues is a comprehensive textbook introducing the burgeoning field of ecomedia studies to provide an overview of the interface between environmental issues and the media globally. Linking the world of media production, distribution, and consumption to environmental understandings, the book addresses ecological meanings encoded in media texts, the environmental impacts of media production, and the relationships between media and cultural perceptions of the environment. Each chapter introduces a distinct type of media, addressing it in a theoretical overview before engaging with specific case studies. In this way, the book provides an accessible introduction to each form of media as well as a sophisticated analysis of relevant cases. The book includes contributions from a combination of new voices and well-established media scholars from across the globe who examine the basic concepts and key issues of ecomedia studies. The concepts of "frames," "flow", and "convergence" structure a dynamic collection divided into three parts. The first part addresses traditional visual texts, such as comics, photography, and film. The second part of the book addresses traditional broadcast media, such as radio, and television, and the third part looks at new media, such as advertising, video games, the internet, and digital renderings of scientific data. In its breadth and scope, Ecomedia: Key Issues presents a unique survey of rich scholarship at the confluence of Media Studies and Environmental Studies. The book is written in an engaging and accessible style, with each chapter including case studies, discussion questions and suggestions for further reading.

The purpose of this volume is to present current work of the Intelligent Computer Graphics community, a community growing up year after year. This volume is a kind of continuation of the previously published Springer volume “Artificial Int- ligence Techniques for Computer Graphics”. Nowadays, intelligent techniques are more and more used in Computer Graphics in order, not only to optimise the pr- essing time, but also to find more accurate solutions for a lot of Computer Gra- ics problems, than with traditional methods. What are intelligent techniques for Computer Graphics? Mainly, they are te- niques based on Artificial Intelligence. So, problem resolution (especially constraint satisfaction) techniques, as well as evolutionary techniques, are used in Declarative scene Modelling; heuristic search techniques, as well as strategy games techniques, are currently used in scene understanding and in virtual world exploration; multi-agent techniques and evolutionary algorithms are used in behavioural animation; and so on. However, even if in most cases the used intelligent techniques are due to Artificial - telligence, sometimes, simple human intelligence can find interesting solutions in cases where traditional Computer Graphics techniques, even combined with Artificial Intelligence ones, cannot propose any satisfactory solution. A good example of such a case is the one of scene understanding, in the case where several parts of the scene are impossible to access.
