Book Description
This book gathers selected papers presented at the conference “Advances in 3D Image and Graphics Representation, Analysis, Computing and Information Technology,” one of the first initiatives devoted to the problems of 3D imaging in all contemporary scientific and application areas. The aim of the conference was to establish a platform for experts to combine their efforts and share their ideas in the related areas in order to promote and accelerate future development. This second volume discusses algorithms and applications, focusing mainly on the following topics: 3D printing technologies; naked, dynamic and auxiliary 3D displays; VR/AR/MR devices; VR camera technologies; microprocessors for 3D data processing; advanced 3D computing systems; 3D data-storage technologies; 3D data networks and technologies; 3D data intelligent processing; 3D data cryptography and security; 3D visual quality estimation and measurement; and 3D decision support and information systems.

Book Description
The images produced by means ofcomputers have invaded our daily lives. One has but to see the "identification logos" of most television broadcasts or some advenisement "spots" to be convinced of this. This proves that the synthesis ofimages has reached maturity. The progress that has been made in the last few years allows one to predict the use ofrealistic illustrations in more and more domains ofapplication. It is thus understandable that more and more people seek to understand how these images are produced. Such a person may be an amateur who likes to understand in a general way the processing involved, or he may be a computer scientist who wants to develop some new application using graphics procedures. This book by Michel Bret meets these desires by giving a complete overview of the techniques of image synthesis by computer. The different stages of the creation of a numerical image are explained in detail, and they are accompanied by descriptions of the most modem methods. Thus the geometrical models that are described go from those with plane polygonal facets, via surfaces of all types, to systems of panicles. Visualization is treated in complete detail, and due attention is given to all the various roads that lead to a realistic image: simple projections on the basis of wire-frame models, the elimination of hidden pans, and fmally the modelling oflight and its effects.

Book Description
This book is a detailed description of the basics of three-dimensional digital image processing. A 3D digital image (abbreviated as “3D image” below) is a digitalized representation of a 3D object or an entire 3D space, stored in a computer as a 3D array. Whereas normal digital image processing is concerned with screens that are a collection of square shapes called “pixels” and their corresponding density levels, the “image plane” in three dimensions is represented by a division into cubical graphical elements (called “voxels”) that represent corresponding density levels. Inthecontextofimageprocessing,in manycases3Dimageprocessingwill refer to the input of multiple 2D images and performing processing in order to understand the 3D space (or “scene”) that they depict. This is a result of research into how to use input from image sensors such as television cameras as a basis for learning about a 3D scene, thereby replicating the sense of vision for humans or intelligent robots, and this has been the central problem in image processing research since the 1970s. However, a completely di?erent type of image with its own new problems, the 3D digital image discussed in this book, rapidly took prominence in the 1980s, particularly in the ?eld of medical imaging. These were recordings of human bodies obtained through computed (or “computerized”) tomography (CT),imagesthatrecordednotonlytheexternal,visiblesurfaceofthesubject but also, to some degree of resolution, its internal structure. This was a type of image that no one had experienced before.

Book Description
Three-Dimensional Imaging Techniques provides an overview of the development and practical applications of three-dimensional imaging techniques. This text deals with holographic and nonholographic techniques, with a focus on efficiency, speckle noise, resolution, white-light reconstruction, white-light recording, and color holography. This book is comprised of nine chapters, wherein Chapter 1 provides a brief history of information media in human society. Chapter 2 presents the history of depth perception and the principle of the Wheatstone stereoscope, and Chapter 3 examines the construction of human eyes as the most important source of depth perception. Chapter 4 focuses on the optimum design of lens-sheet pictures, whereas Chapters 5 and 6 examine the technical drawbacks that limit the versatility in three-dimensional imaging technology. The features of holographic techniques, such as holographic stereoscreens and computer-generated holograms, are discussed in Chapters 7 and 8. Finally, Chapter 9 discusses the possible classifications based on applications, including microscopy, television, X-ray imaging, movies, and acoustical imaging. This book is intended for electronic engineers, researchers, and readers who are interested in the field of three-dimensional imaging.

Book Description
There exists many devices that generate three-dimensional illumination patterns. Analysis of the capabilities of three major device families using measures of partial coherence reveals specific illumination patterns that cannot be generated by each device family. Ray-based devices cannot achieve patterns with high resolution, coherent holographic devices cannot achieve certain intensity patterns, even in the two-dimensional case, and volumetric devices cannot simulate occlusions and suffer from out-of-focus blur. Synthesis of more versatile illumination patterns is proposed by computing the mutual intensity representation of a desired partially coherent beam from application specifications and then generating the beam using time-multiplexing methods based on coherent modes. The mutual intensity can be computed directly from a simple scene description, or it can be computed through a novel algorithm using nonlinear conjugate gradients from a desired three-dimensional intensity volume. Equivalent coherent mode decomposition representations for the same mutual intensity will be considered in terms of optimality in efficiency. For cases when the computed mutual intensity is fairly incoherent, a new "quasi-Schell" mode decomposition is proposed to reduce the number of patterns needed at the SLM by introducing partially coherent sources. Use of arbitrary partially coherent beams for three-dimensional illumination enables the versatile generation of light patterns not possible with current devices and is a promising new field for exploration.

Book Description
Image synthesis across and within medical imaging modalities is an active area of research with broad applications in radiology and radiation oncology. This book covers the principles and methods of medical image synthesis, along with state-of-the-art research. First, various traditional non-learning-based, traditional machine-learning-based, and recent deep-learning-based medical image synthesis methods are reviewed. Second, specific applications of different inter- and intra-modality image synthesis tasks and of synthetic image-aided segmentation and registration are introduced and summarized, listing and highlighting the proposed methods, study designs, and reported performances with the related clinical applications of representative studies. Third, the clinical usages of medical image synthesis, such as treatment planning and image-guided adaptive radiotherapy, are discussed. Last, the limitations and current challenges of various medical synthesis applications are explored, along with future trends and potential solutions to solve these difficulties. The benefits of medical image synthesis have sparked growing interest in a number of advanced clinical applications, such as magnetic resonance imaging (MRI)-only radiation therapy treatment planning and positron emission tomography (PET)/MRI scanning. This book will be a comprehensive and exciting resource for undergraduates, graduates, researchers, and practitioners.
