Preface of the Book: "High-Quality Visual Experience - Creation, Processing and Interactivity of High-Resolution and High-Dimensional Video Signals"

Last few years have seen rapid acceptance of high-definition television (HDTV) technology around the world. This technology has been hugely successful in delivering more realistic television experience at home and accurate imaging for professional applications. Adoption of high definition continues to grow as consumers demand enhanced features and greater quality of content. Following this trend, natural evolution of visualisation technologies will be in the direction of fully realistic visual experience and highly precise imaging. How-ever, using the content of even higher resolution and quality is not straightforward as such videos require significantly higher access bandwidth and more processing power. Therefore, methods for radical reduction of video bandwidth are crucial for realisation of high visual quality. Moreover, it is desirable to look into other ways of accessing visual content, solution to which lies in innovative schemes for content delivery and consumption. This book presents selected chapters covering technologies that will enable greater flexibility in video content representation and allow users to access content from any device and to interact with it. This book is divided into five parts: (i) Quality of visual information, (ii) Video coding for high resolutions, (iii) Visual content upscaling, (iv) 3D visual content processing and displaying, (v) Accessing technologies for visual content. Part I on quality of visual information introduces metrics and examples that are basics for evaluation of quality of high-resolution and high-dimensional visual data. This part of the book is addressed with three chapters. Chapter 1 introduces objective video quality assessment methods. In Chapter 2 the subjective video quality is addressed in terms of the quality of experience for specific case - digital cinema. Quality of 3D visual data is discussed in Chapter 3, where different qual-ity metrics are evaluated for application on stereoscopic images. The following part addresses the necessary technology that enables wide access to high resolution visual data - video compression methods. Chapter 4 brings an overview of state-of-the-art in video coding and introduces recent developments in ultra-high definition compression. Further details of current video coding standards and evaluation of their performance for high definition videos are given in Chapter 5. Two systems that support ultra-high definition are presented in Chapters 6 and 7. In addition to the codecs for high resolutions, high frame rate videos are addressed in Chapter 8 where the related mathematical modelling method is given. Methods for creation of content of higher frame rates and higher resolution are presented in Part III. Temporal content upscaling is in the focus of Chapters 9 to 11. Chapter 12 addresses the problem of natural image synthesis from low resolu-tion images. Technologies needed for 3D content creation, processing and displaying are presented in Part IV. Chapter 13 investigates the role of colour information in solving stereo correspondence problem. 3D object classification and segmentation methods are presented in Chapter 14. The techniques for generation and handling of videos combined from captured 3D content and computer graphics is proposed in Chapter 15. Discussion on this topic continues with Chapter 16 where a new approach for generation of 3D content is proposed. Chapter 17 brings detailed overview of 3D displaying technology, while Chapter 18 focuses on integral imag-ing. Accessing technologies for visual content of high resolution and dimensions are presented in Part V. The techniques enabling video streaming with spatial random access are presented in Chapter 19. Chapter 20 addresses management of heterogeneous environments for enabling quality of experience. Transmission of 3D video is in the focus of Chapter 21 which presents a solution designed for wireless networks. Methods for retrieval of high-resolution videos are addressed in Chapter 22. Moreover, in Chapter 23 stereo correspondence methods are ad-dressed in the context of video retrieval. We believe that this collection of chapters provides balanced set of critical technologies that will facilitate development of future multimedia systems sup-porting high quality of experience. The refreshing perspectives of looking into visual data handling presented in this book complement current commercial visual technologies. Therefore, this book is essential to those whose interest is in futuristic high-quality visualisation systems.
