Communicating Pictures starts with a unique historical perspective of the role of images in communications and then builds on this to explain the applications and requirements of a modern video coding system. It draws on the author's extensive academic and professional experience of signal processing and video coding to deliver a text that is algorithmically rigorous, yet accessible, relevant to modern standards, and practical. It offers a thorough grounding in visual perception, and demonstrates how modern image and video compression methods can be designed in order to meet the rate-quality performance levels demanded by today's applications, networks and users. With this book you will learn: Practical issues when implementing a codec, such as picture boundary extension and complexity reduction, with particular emphasis on efficient algorithms for transforms, motion estimators and error resilience Conflicts between conventional video compression, based on variable length coding and spatiotemporal prediction, and the requirements for error resilient transmission How to assess the quality of coded images and video content, both through subjective trials and by using perceptually optimised objective metrics Features, operation and performance of the state-of-the-art High Efficiency Video Coding (HEVC) standard Covers the basics of video communications and includes a strong grounding in how we perceive images and video, and how we can exploit redundancy to reduce bitrate and improve rate distortion performance Gives deep insight into the pitfalls associated with the transmission of real-time video over networks (wireless and fixed) Uses the state-of- the-art video coding standard (H.264/AVC) as a basis for algorithm development in the context of block based compression Insight into future video coding standards such as the new ISO/ITU High Efficiency Video Coding (HEVC) initiative, which extends and generalizes the H.264/AVC approach

Intelligent Image and Video Compression: Communicating Pictures, Second Edition explains the requirements, analysis, design and application of a modern video coding system. It draws on the authors’ extensive academic and professional experience in this field to deliver a text that is algorithmically rigorous yet accessible, relevant to modern standards and practical. It builds on a thorough grounding in mathematical foundations and visual perception to demonstrate how modern image and video compression methods can be designed to meet the rate-quality performance levels demanded by today's applications and users, in the context of prevailing network constraints. Key Features An approach that combines algorithmic rigor with practical implementation using numerous worked examples Explains how video compression methods exploit statistical redundancies, natural correlations, and knowledge of human perception to improve performance Uses contemporary video coding standards (AVC, HEVC and VVC) as a vehicle for explaining block-based compression Provides broad coverage of important topics such as visual quality assessment and video streaming New to this edition: Coverage of new, more immersive applications, explaining compression requirements and solutions for HDR and UHDTV, VR, AR, and MR Description of how we can measure viewer engagement with these applications An introduction to machine learning algorithms and coverage of how these can be used to optimize future compression tools Inclusion of the latest advances in perceptual metrics, such as VMAF Description of new and extended databases for video quality evaluation and for training machine learning systems Coverage of recent innovations and standards to support adaptive video streaming A review of the perceptual influences of dynamic range including descriptions of perceptual quantization and new formats A comprehensive coverage of recent compression standards including AV1 and VVC.

ambiguity revisited is concerned with the manner in which pictures communicate with the spectator. Its focus lies in those fluid, indeterminate spaces where our reading of images, in art and photography, exercises and draws upon our imagination, memory, and experience. Sir William Empson's seminal (1930) text: Seven Types of Ambiguity is used as a springboard to discussion, towards a fresh way of exploring ambiguity beyond English literature, and in a broader framework to that contained in John Berger's (1989) Another Way of Telling. The use of ambiguity in art and photography, as in literature, is both a conscious and an unconscious act; and ambiguity influences the way in which we respond to work, from Leonardo da Vinci's portraits to the photographer William Eggleston's engaging and idiosyncratic reflections on America's Deep South. This ambiguity is a force for good, or at least one to be reckoned with, due to its participatory nature in actively engaging with, or masking itself from, the viewer. Ambiguity is infrequently discussed but is highly relevant as an expressive device. It holds a position at the core of communication within the visual arts. As society becomes influenced increasingly by communications delivered in a visual form, so we, the consumers, require tools, more than ever, to engage with the work.
