Book Description
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

Book Description
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. "David Bull and Fan Zhang have written a timely and accessible book on the topic of image and video compression. Compression of visual signals is one of the great technological achievements of modern times, and has made possible the great successes of streaming and social media and digital cinema. Their book, Intelligent Image and Video Compression covers all the salient topics ranging over visual perception, information theory, bandpass transform theory, motion estimation and prediction, lossy and lossless compression, and of course the compression standards from MPEG (ranging from H.261 through the most modern H.266, or VVC) and the open standards VP9 and AV-1. The book is replete with clear explanations and figures, including color where appropriate, making it quite accessible and valuable to the advanced student as well as the expert practitioner. The book offers an excellent glossary and as a bonus, a set of tutorial problems. Highly recommended! --Al Bovik - 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

Book Description
This book presents an updated description of The Picture Exchange Communication System (PECS). It begins with a discussion of the "big picture," or the authors view on the importance of laying the foundation for communication training by systematically structuring the learning environment (be it in the home, community or school). This approach, The Pyramid Approach to Education, embraces the principals of broad-spectrum applied behavior analysis and emphasizes the development of functional communication skills, independent of communication modality. The Pyramid Approach is one of the few approaches that encourages creativity and innovation on the teacher's part through databased decision making.

Book Description
Ours is the age of the picture. Pictures abound in our newspapers and magazines, in storybooks and on the glossy pages of instruction manuals. We find them on billboards and postage stamps, on the television screen and in the cinema. And in all of these cases pictures inform us: they explain, they clarify, they elucidate - and at times, too, they entertain and delight us. Images on the television screen have all but replaced the printed word as a source of information about the world; and nowadays, too, picture books and comic strips are consulted much more readily, and with much less intellectual effort, than the printed word. There can be little doubt but that pictures have come to play a very important role in communication. It strikes me as odd that, in what is nothing less than a visual age, philosophers have had so little to say about the visual image and its use in communication. Hardly anything has been done to explain the way in which pictures are used to inform us; the way in which they influence our thinking, our attitudes and our perception of the world. My aim in this work is to fill this gap, and in so doing to provide a viable account of pictorial communication.

Book Description
This guide will help children's nurses to communicate with confidence, sensitivity and effectiveness; to meet the individual needs of children and their families. The book explores different aspects of communicating in this challenging environment using vignettes, examples, practice insights and tips. The book emphasises the importance of listening to and respecting children's views and rights, in addition to respecting parent responsibility, rights and duty to act in the child's best interests. The authors show how a balance between protective exclusion and facilitated inclusion is core to communicating with children and families.

Book Description
Social media increasingly shapes the way in which we perceive conflicts and conflict parties abroad. Conflict parties, therefore, have started using social media strategically to influence public opinion abroad. This book explores the phenomenon by examining, (1) which strategies of external communication conflict parties use during asymmetric conflicts and (2) what shapes the selection of these communication strategies. In a comprehensive case study of the conflict in Israel and Palestine, Bernd Hirschberger shows that the selection of strategies of external communication is shaped by the (asymmetric) conflict structure.
