This is a comprehensive survey of binocular vision, with an emphasis on its role in the perception of a three-dimensional world. The central theme is biological vision. Machine vision and computational models are discussed where they contribute to an understanding of living systems.

Biological and machine systems exist within a complex and changing three-dimensional world. We appear to have no difficulty understanding this world, but how do we go about forming a perceptual model of it? Centred around three key themes: depth processing and stereopsis; motion and navigation in 3D; and natural scene perception, this volume explores the latest cutting-edge research into the perception of three dimension environments. It features contributions from top researchers in the field, presenting both biological and computational perspectives. Topics covered include binocular perception; blur and perceived depth; stereoscopic motion in depth; and perceiving and remembering the shape of visual space. This unique book will provide students and researchers with an overview of ongoing research as well as perspectives on future developments in the field. Colour versions of a selection of the figures are available at www.cambridge.org/9781107001756.

Tasks related to motion perception are some of the most frequent and important for surviving in a world filled with motion. Animals face tremendous evolutionary pressure to develop accurate systems for estimating the velocity of moving objects and predicting future trajectories. Motion detection and estimation were crucial for survival because they enabled animals to avoid being caught by predators and for predators to capture prey. Today, the visual system enables us to interact with the dynamic modern world we live in. Due to its clear evolutionary significance the study of motion has been common in vision science. Many prior studies have focused on two-dimensional (2D) motion perception and depth perception separately. Fewer studies have explicitly studied three-dimensional (3D) motion perception. This dissertation situates itself within a recent trend that focuses on the study of 3D motion by using a unified framework considering both motion and depth. I present two major projects that advance the study of 3D motion perception. First, I introduce novel stimuli that isolate the primary binocular cues to 3D motion. These novel stimuli allow for the characterization of two separate mechanisms that underlie the perception of motion-through-depth. I present two psychophysics experiments that use these stimuli to characterize the spatiotemporal properties of these mechanisms. In the second project, I extend the powerful continuous tracking paradigm to virtual reality (VR) to study the relative contribution of binocular and monocular cues to 3D motion. This chapter highlights the limitations of disparity processing and the contribution of monocular depth cues for a 3D motion tracking task. The work in this dissertation falls at a midpoint on the spectrum between traditional approaches to psychophysics and more recent developments using naturalistic stimuli and tasks. Taken together, the results described here advance what we know about binocular and monocular mechanisms for the perception of motion-through-depth. This work forms a foundation for testing how the primate visual system makes use of a variety of depth and motion cues to encode 3D motion. Future studies may further explore how coordination between the motion and motor systems enable us to interact with a dynamic 3D world

There has been growing acceptance of the insight that the methods so far used in the testing of visual functions have been inadequate when it comes to specific problems and should, therefore, be supplemented with more specialised methods for dynamic testing. As long as two decades ago, large-scale mass screening produced evidence to the effect that visual acuity, so far exclusively determined by means of still samples, was not identical with visual acuity in the ocular pursuit of moving targets (dynamic visual acuity). In other words, vision testing can, at present, provide little informa tion on an individual's capability of identification, appreciation, and judge ment of mobile objects. Spatial, three-dimensional perception of moving targets, hereafter re ferred to as dynamic stereoacuity, is the particular subject on which findings are reported in this article. Findings of that kind are of considerable relevance to everyday life, since many of the phenomena that have to be three-dimensionally perceived in private life and in occupational practice, are in movement. So far, dynamic stereoacuity has never been systematical ly studied and is still a blank space on the maps of ophthalmology and physiology. This is equally true for dynamic stereoscopy in binocular vision as well as for perception on the basis of movement parallax, a phenomenon of differentiated contour displacement within a given field of vision which is also available to the monocular individual under conditions of head or body or object movement within the visual space.

Vision is our most dominant sense, from which we derive most of our information about the world. From the light that enters the eye and the processing in the brain that follows we can sense where things are, how they move and what they are. The first edition of Visual Perception took a refreshingly different approach to perception, starting from the function that vision serves for an active observer in a three-dimensional environment. This fully revised and expanded new edition continues this approach in contrast to the traditional textbook treatment of vision as a catalogue of phenomena. Following a general introduction to the main theoretical approaches, the authors discuss the historical basis of our current knowledge. Placing the study of vision in its historical context, they look at how our ideas have been shaped by art, optics, biology and philosophy as well as psychology. Visual optics and the neurophysiology of vision are also described. The core of the book covers the perception of location, motion and object recognition. There is a new chapter on representation and vision, including a section on the perception of computer generated images. This readable, accessible and truly relevant introduction to the world of perception aims to elicit both independent thought and further study. It will be welcomed by students of visual perception and those with a general interest in the mysteries of vision.

The three-volume work Perceiving in Depth is a sequel to Binocular Vision and Stereopsis and to Seeing in Depth, both by Ian P. Howard and Brian J. Rogers. This work is much broader in scope than the previous books and includes mechanisms of depth perception by all senses, including aural, electrosensory organs, and the somatosensory system. Volume 1 reviews sensory coding, psychophysical and analytic procedures, and basic visual mechanisms. Volume 2 reviews stereoscopic vision. Volume 3 reviews all mechanisms of depth perception other than stereoscopic vision. The three volumes are extensively illustrated and referenced and provide the most detailed review of all aspects of perceiving the three-dimensional world. Volume 2 addresses stereoscopic vision in cats and primates, including humans. It begins with an account of the physiology of stereoscopic mechanisms. It then deals with binocular rivalry, binocular summation, binocular masking, and the interocular transfer of visual effects, such as the motion aftereffect and visual learning. The geometry of the region in binocular space that creates fused images (the horopter) is discussed in some detail. Objects outside the horopter produce images with binocular disparities that are used for stereoscopic vision. Two chapters provide accounts of mechanisms that bring the images into binocular register and of stimulus tokens that are used to detect binocular disparities. Another chapter discusses cyclopean effects, such as cyclopean illusions, cyclopean motion, and binocular direction that are seen only with binocular vision. Stereoacuity is the smallest depth interval that can be detected. Methods of measuring stereoacuity and factors that influence it are discussed. Two chapters deal with the various types of binocular disparity and the role of each type in stereoscopic vision. Another chapter deals with visual effects, such as figure perception, motion perception, and whiteness perception that are affected by the relative distances of stimuli. The spatiotemporal aspects of stereoscopic vision, including the Pulfrich stereomotion effect are reviewed. The volume ends with an account of techniques used to create stereoscopic displays and of the applications of stereoscopy.
