The more than twenty contributions in this book, all new and previously unpublished, provide an up-to-date survey of contemporary research on computational modeling of the visual system. The approaches represented range from neurophysiology to psychophysics, and from retinal function to the analysis of visual cues to motion, color, texture, and depth. The contributions are linked thematically by a consistent consideration of the links between empirical data and computational models in the study of visual function. An introductory chapter by Edward Adelson and James Bergen gives a new and elegant formalization of the elements of early vision. Subsequent sections treat receptors and sampling, models of neural function, detection and discrimination, color and shading, motion and texture, and 3D shape. Each section is introduced by a brief topical review and summary. ContributorsEdward H. Adelson, Albert J. Ahumada, Jr., James R. Bergen, David G. Birch, David H. Brainard, Heinrich H.

This book is divided into five sections dealing with various fundamental issues in current research: attention, information processing and eye movement control; the role of phonology in reading; syntax and discourse processing and computational models and simulations. Control and measurement of eye movements form a prominent theme in the book. A full understanding of the where and when of eye movement control is a prerequisite of any complete theory of reading, since it is precisely at this point that perceptual and cognitive processes interact. Amongst the 'hot topics' included are the relation between parafoveal and foveal visual processing of linguistic information, the role of phonology in fluent reading and the emergence of statistical 'tuning' approaches to sentence parsing.Also discussed in the book are three attempts to develop quantitative models of reading which represent a significant departure in theory-building and a quantum step in the maturation of reading research. Much of the work reported in the book was first presented at the 5th European Workshop on Language Comprehension organised in April 1998 which was held at the CNRS Luminy Campus, near Marseilles. All contributions summarise the state-of-the-art in the relevant areas of reading research.

"This book describes computational models of reading, or models that simulate and explain the mental processes that support the reading of text. The book provides introductory chapters on both reading research and computer models. The central chapters of the book then review what has been learned about reading from empirical research on four core reading processes: word identification, sentence processing, discourse representation, and how these three processes are coordinated with visual processing, attention, and eye-movement control. These central chapters also review an influential sample of computer models that have been developed to explain these key empirical findings, as well as comparative analyses of those models. The final chapter attempts to integrate this empirical and theoretical work be both describing a new comprehensive model of reading, Über-Reader, and reporting several simulations to illustrate how the model accounts for many of the basic phenomena related to reading"--

This text provides an introduction to computational aspects of early vision, in particular, color, stereo, and visual navigation. It integrates approaches from psychophysics and quantitative neurobiology, as well as theories and algorithms from machine vision and photogrammetry. When presenting mathematical material, it uses detailed verbal descriptions and illustrations to clarify complex points. The text is suitable for upper-level students in neuroscience, biology, and psychology who have basic mathematical skills and are interested in studying the mathematical modeling of perception.

Measurement and analysis of eye movements are two of the most powerful ways to study the workings of the human mind. This Special Issue on eye movements and information processing in reading presents an overview of experimental research based on this methodology. Eye movements provide a unique opportunity to examine principles of human information processing in a well-structured visual environment while people engage in a natural cognitive task. At the same time, oculomotor measures can be used as a tool to develop and test psycholinguistic hypotheses about the processing of written language. The papers in this issue contribute to both aspects, addressing issues that dominate current debates in the field. Seen from the angle of visual information processing, a major theme is the role played by parafoveal information for different types and levels of processing and for oculomotor control in reading. This includes effects of visual and linguistic word properties on the selection of words for fixation and the specification of saccade amplitudes. Clearly the most controversial question in this context concerns the allocation of attention, with positions ranging from a sequentially moving spotlight to a gradient of spatially distributed processing. Related to this is the issue of serial vs. parallel word processing and the fundamental question as to what extent the duration of fixations in reading is related to lexical processing. Taking a psycholinguistic perspective, the topics addressed include several levels of language processing from orthography to pragmatic information in sentence reading. New approaches to the study of morphologically complex words are reported, together with novel work revealing the complex nature of the apparently accessible, but elusive, concept of word frequency. Other papers reflect current theoretical discussions centered on the development of computational models of the reading process and contribute to the empirical base of these discussions. Taken together, this collection of papers, supplemented by an introduction to the field and a commentary on major issues, presents a comprehensive and up-to-date perspective on a research area currently characterised by numerous theoretical and empirical disputes. The papers will be of particular appeal to readers interested in basic and applied psycholinguistics, attention and visual perception, motor control and the modelling of complex cognitive processes.

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 heretofore been little progress on integrating these subareas of Artificial Intelligence (AI). This book contains a set of edited papers addressing computational models and systems for the integration of NLP and VP. The papers focus on site descriptions such as that of the large Japanese $500 million Real World Computing (RWC) project, on historical philosophical issues, on systems which have been built and which integrate the processing of visual scenes together with language about them, and on spatial relations which appear to be the key to integration. The U.S.A., Japan and the EU are well reflected, showing up the fact that integration is a truly international issue. There is no doubt that all of this will be necessary for the InformationSuperHighways of the future.

This paper is the first of a series aimed at developing a theory of early visual processing in reading. We suggest that there has been a close parallel in the development of theories of reading and theories of vision in artificial intelligence. We propose to exploit and extend recent results in computer vision to develop an improved model of early processing in reading. This paper considers the problem of isolating words in text based on the information which Marr and Hildreth's (1980) theory asserts is available in the parafovea. We show in particular that the findings of Fisher (1975) on reading transformed texts can be accounted for without postulating the need for complex interactions between early processing and downflowing information as he suggests. The paper concludes with a brief discussion of the problem of integrating information over successive saccades, and relates the earlier analysis to the empirical findings of Rayner.
