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
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
Inverse Synthetic Aperture Radar (ISAR) provides full-range detection and classification of sea-based and air-based targets through two-dimensional range-Doppler imaging. The Naval Postgraduate School (NPS) has developed a custom integrated circuit that can simulate false ISAR images in order to fool enemy ISAR platforms. To validate specific hardware choices within this design, this thesis explores the effect on image quality of an overflow occurring within the final 16-bit summation adder of this circuit, Three solutions to the problem of overflows are presented and analyzed. The logical extension of ISAR development, that of three-dimensional target imaging, is next presented through the discussion of 3D monopulse radar, 3D interferometer ISAR, and a 3D, three- receiver ISAR. The relative strengths of each approach are compared, along with both MATLAB and Extensible 3D (X3D) Graphics software models created for one specific 3D ISAR implementation. Through the superposition of 2D ISAR images it is shown how 3D ISAR images may be created. Moreover, emphasis is placed on using this knowledge to both enhance current 2D ISAR techniques and to modify the false-target chip design to handle 3D ISAR return signals. The thesis concludes with a study of Non-Uniform Rational 13-Splines, through which the X3D software model was created.
