Measurement of Image Velocity presents a computational framework for computing motion information from sequences of images. Its specific goal is the measurement of image velocity (or optical flow), the projection of 3-D object motion onto the 2-D image plane. The formulation of the problem emphasizes the geometric and photometric properties of image formation, and the occurrence of multiple image velocities caused, for example, by specular reflections, shadows, or transparency. The method proposed for measuring image velocity is based on the phase behavior in the output of velocity-tuned filters. Extensive experimental work is used to show that phase can be a reliable source of pure image translation, small geometric deformation, smooth contrast variations, and multiple local velocities. Extensive theorectical analysis is used to explain the robustness of phase with respect to deviations from image translation, and to detect situations in which phase becomes unstable. The results indicate that optical flow may be extracted reliably for computing egomotion and structure from motion. The monograph also contains a review of other techniques and frequency analysis applied to image sequences, and it discusses the closely related topics of zero-crossing tracking, gradient-based methods, and the measurement of binocular disparity. The work is relevant to those studying machine vision and visual perception.

Although there has been much progress in developing theories, models and systems in the areas of natural language processing (NLP) and vision processing (VP), there has hitherto been little progress in integrating these two subareas of artificial intelligence. The papers in Integration of Natural Language and Vision Processing focus on site descriptions, such as the work at Apple Computer, California, and the DFKI, Saarbrucken, on historical surveys and philosophical issues, on systems that have been built, enabling communication through text, speech, sound, touch, video, graphics and icons, and on the automatic presentation of information, whether it be in the form of instruction manuals, statistical data or visualisation of language. There is also a review of Mark Maybury's book Intelligent Multimedia Interfaces. Audience: Vital reading for all interested in the SuperInformationHighways of the future.

An Analog VLSI System for Stereoscopic Vision investigates the interaction of the physical medium and the computation in both biological and analog VLSI systems by synthesizing a functional neuromorphic system in silicon. In both the synthesis and analysis of the system, a point of view from within the system is adopted rather than that of an omniscient designer drawing a blueprint. This perspective projects the design and the designer into a living landscape. The motivation for a machine-centered perspective is explained in the first chapter. The second chapter describes the evolution of the silicon retina. The retina accurately encodes visual information over orders of magnitude of ambient illumination, using mismatched components that are calibrated as part of the encoding process. The visual abstraction created by the retina is suitable for transmission through a limited bandwidth channel. The third chapter introduces a general method for interchip communication, the address-event representation, which is used for transmission of retinal data. The address-event representation takes advantage of the speed of CMOS relative to biological neurons to preserve the information of biological action potentials using digital circuitry in place of axons. The fourth chapter describes a collective circuit that computes stereodisparity. In this circuit, the processing that corrects for imperfections in the hardware compensates for inherent ambiguity in the environment. The fifth chapter demonstrates a primitive working stereovision system. An Analog VLSI System for Stereoscopic Vision contributes to both computer engineering and neuroscience at a concrete level. Through the construction of a working analog of biological vision subsystems, new circuits for building brain-style analog computers have been developed. Specific neuropysiological and psychophysical results in terms of underlying electronic mechanisms are explained. These examples demonstrate the utility of using biological principles for building brain-style computers and the significance of building brain-style computers for understanding the nervous system.

The range of applications in the area of motion analysis and image sequence processing is expanding with the steady increase in the use of video and television systems in a variety of different fields. A consequence of this expansion is the increased interest in research in this area. Motion Analysis and Image Sequence Processing brings together the fundamentals of various aspects of image sequence processing, as well as the most recent developments and applications. An image sequence is a series of two-dimensional images that are sequentially ordered in time. The analysis of image motion, and processing of image sequences using the motion information is becoming more and more important as video and television systems are finding an increasing number of applications in the areas of entertainment, robot vision, education, personal communications, multimedia, and scientific research. The importance of motion analysis and image sequence processing is due to two major factors. First, the information that needs to be obtained from the sequence may be inherently time-dependent. In that case, spatial information that can be obtained from a single image frame may not bear any useful information, and hence one must utilize temporal information by considering a sequence of images. Second, in some applications it may be advantageous to consider the processing of a sequence of images instead of individual images. This is because one can utilize the naturally existing temporal relationship among the frames of an image sequence to obtain results that are superior to those obtained by frame-by-frame processing of the sequence. Motion Analysis and Image Sequence Processing contains a coherent and rigorous discussion of recent fundamental developments, as well as applications of motion estimation and image sequence processing. Motion Analysis and Image Sequence Processing is a useful reference for engineers, industrial and academic research scientists, graduate students and faculty who are either already active in research in the field or planning to pursue research in one or more aspects of image sequence processing. This book can be used as the textbook in an advanced level course and as a reference.

This book is an introduction to the fundamental concepts and tools needed for solving problems of a geometric nature using a computer. It attempts to fill the gap between standard geometry books, which are primarily theoretical, and applied books on computer graphics, computer vision, robotics, or machine learning.

Video Object Extraction and Representation: Theory and Applications is an essential reference for electrical engineers working in video; computer scientists researching or building multimedia databases; video system designers; students of video processing; video technicians; and designers working in the graphic arts. In the coming years, the explosion of computer technology will enable a new form of digital media.

The book reviews relevant technologies and standards for content-based processing and their interrelations. Within this overview, the book focuses upon two problems at the heart of the algorithmic/computational infrastructure: video object extraction, or how to automatically package raw visual information by content; and video object representation, or how to automatically index and catalogue extracted content for browsing and retrieval.The book analyzes the designs of two novel, working systems for content-based extraction and representation in the support of MPEG-4 and MPEG-7 video standards, respectively. Features of the book include: * Overview of MPEG standards; * A working system for automatic video object segmentation; * A working system for video object query by shape; * Novel technology for a wide range of recognition problems; * Overview of neural network and vision technologies Video Object Extraction and Representation: Theory and Applications will be of interest to research scientists and practitioners working in fields related to the topic.
