Book Description

Handbook of Perception, Volume VIII: Perceptual Coding covers perceptual coding of space, time, and objects, including sensory memory systems and the relations between verbal and perceptual codes. This volume contains contributions that focus on such subjects as the compound eye; the problems of the perceptual constancies and of intersensory coordination in perceptual development; the visual perception of objects in space; and perception of motion. Topics on the perception of color, the representation of temporal, auditory, and haptic perception; and the relationship between verbal and perceptual codes are discussed in detail as well. This book will be of use to psychologists, biologists, and those interested in the study of perceptual codes.

Book Description

The hand is quicker than the eye. In many cases, so is digital video. Maintaining image quality in bandwidth- and memory-restricted environments is quickly becoming a reality as thriving research delves ever deeper into perceptual coding techniques, which discard superfluous data that humans cannot process or detect. Surveying the topic from a Human Visual System (HVS)-based approach, Digital Video Image Quality and Perceptual Coding outlines the principles, metrics, and standards associated with perceptual coding, as well as the latest techniques and applications. This book is divided broadly into three parts. First, it introduces the fundamental theory, concepts, principles, and techniques underlying the field, such as the basics of compression, HVS modeling, and coding artifacts associated with current well-known techniques. The next section focuses on picture quality assessment criteria; subjective and objective methods and metrics, including vision model based digital video impairment metrics; testing procedures; and international standards regarding image quality. Finally, practical applications come into focus, including digital image and video coder designs based on the HVS as well as post-filtering, restoration, error correction, and concealment techniques. The permeation of digital images and video throughout the world cannot be understated. Nor can the importance of preserving quality while using minimal storage space, and Digital Video Image Quality and Perceptual Coding provides the tools necessary to accomplish this goal. Instructors and lecturers wishing to make use of this work as a textbook can download a presentation of 786 slides in PDF format organized to augment the text. accompany our book (H.R. Wu and K.R. Rao, Digital Video Image Quality and Perceptual Coding, CRC Press (ISBN: 0-8247-2777-0), Nov. 2005) for lecturers or instructor to use for their classes if they use the book.

Book Description

The requirements for multimedia (especially video and audio) communications increase rapidly in the last two decades in broad areas such as television, entertainment, interactive services, telecommunications, conference, medicine, security, business, traffic, defense and banking. Video and audio coding standards play most important roles in multimedia communications. In order to meet these requirements, series of video and audio coding standards have been developed such as MPEG-2, MPEG-4, MPEG-21 for audio and video by ISO/IEC, H.26x for video and G.72x for audio by ITU-T, Video Coder 1 (VC-1) for video by the Society of Motion Picture and Television Engineers (SMPTE) and RealVideo (RV) 9 for video by Real Networks. AVS China is the abbreviation for Audio Video Coding Standard of China. This new standard includes four main technical areas, which are systems, video, audio and digital copyright management (DRM), and some supporting documents such as consistency verification. The second part of the standard known as AVS1-P2 (Video - Jizhun) was approved as the national standard of China in 2006, and several final drafts of the standard have been completed, including AVS1-P1 (System - Broadcast), AVS1-P2 (Video - Zengqiang), AVS1-P3 (Audio - Double track), AVS1-P3 (Audio - 5.1), AVS1-P7 (Mobile Video), AVS-S-P2 (Video) and AVS-S-P3 (Audio). AVS China provides a technical solution for many applications such as digital broadcasting (SDTV and HDTV), high-density storage media, Internet streaming media, and will be used in the domestic IPTV, satellite and possibly the cable TV market. Comparing with other coding standards such as H.264 AVC, the advantages of AVS video standard include similar performance, lower complexity, lower implementation cost and licensing fees. This standard has attracted great deal of attention from industries related to television, multimedia communications and even chip manufacturing from around the world. Also many well known companies have joined the AVS Group to be Full Members or Observing Members. The 163 members of AVS Group include Texas Instruments (TI) Co., Agilent Technologies Co. Ltd., Envivio Inc., NDS, Philips Research East Asia, Aisino Corporation, LG, Alcatel Shanghai Bell Co. Ltd., Nokia (China) Investment (NCIC) Co. Ltd., Sony (China) Ltd., and Toshiba (China) Co. Ltd. as well as some high level universities in China. Thus there is a pressing need from the instructors, students, and engineers for a book dealing with the topic of AVS China and its performance comparisons with similar standards such as H.264, VC-1 and RV-9.

Book Description

This volume is about the many ways we perceive. In nineteen new essays, philosophers and cognitive scientists explore the nature of the individual senses, how and what they tell us about the world, and how they interrelate. They consider how the senses extract perceptual content from receptoral information and what kinds of objects we perceive and whether multiple senses ever perceive a single event. Questions pertaining to how many senses we have, what makes one sense distinct from another, and whether and why distinguishing senses may be useful feature prominently. Contributors examine the extent to which the senses act in concert, rather than as discrete modalities, and whether this influence is epistemically pernicious, neutral, or beneficial. Many of the essays engage with the idea that it is unduly restrictive to think of perception as a collation of contents provided by individual sense modalities. Rather, contributors contend that to understand perception properly we need to build into our accounts the idea that the senses work together. In doing so, they aim to develop better paradigms for understanding the senses and thereby to move toward a better understanding of perception.

Book Description

"Perception and cognition are tightly related. As our primary mode of contact with the world, perception is the informational and causal foundation of our cognitive processes; it is fundamental to our empirical thinking, believing, and action planning. Traditional accounts of the mind consider perception and cognition to be distinct, yet highly interrelated, systems. Much interdisciplinary empirical and theoretical work, from cognitive scientists and philosophers, has attempted to elucidate the complex relations holding among these systems, suggesting the existence not only of influences of perception on cognition but also vice versa. However, many questions are left unanswered. Given that perception is a guide to our thinking about and acting upon the world appropriately, the two systems must be able to 'talk' to one another; information carried by perception must be of a form adequate to be 'taken in' by our various cognitive systems. The question arises: What kinds of structural similarities must hold between perceptual and cognitive representations for such 'communication' to be possible? And how exactly do perceptual and cognitive representations interact? Some researchers have argued that the links between perception and cognition are so tight as to instill doubt as to the significance of the distinction between the two systems in the first place. Yet others insist that perception and cognition remain distinct. The aim of this Research Topic is to deepen our understanding of the kinds of interaction among perception and cognition and of the nature of the representational structures that would enable such interaction." -- Provided by publisher.
