Motion processing is an essential piece of the complex brain machinery that allows us to reconstruct the 3D layout of objects in the environment, to break camouflage, to perform scene segmentation, to estimate the ego movement, and to control our action. Although motion perception and its neural basis have been a topic of intensive research and modeling the last two decades, recent experimental evidences have stressed the dynamical aspects of motion integration and segmentation. This book presents the most recent approaches that have changed our view of biological motion processing. These new experimental evidences call for new models emphasizing the collective dynamics of large population of neurons rather than the properties of separate individual filters. Chapters will stress how the dynamics of motion processing can be used as a general approach to understand the brain dynamics itself.

The contributors to this book focus on such key aspects of motion processing as interaction and integration between locally measured motion units, structure from motion, heading in an optical flow, and second-order motion. They also discuss the interaction of motion processing with other high-level visual functions such as surface representation and attention.

The more than twenty contributions in this book, all new and previously unpublished, provide an up-to-date survey of contemporary research on computational modeling of the visual system.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.

As the state-of-the-art imaging technologies became more and more advanced, yielding scientific data at unprecedented detail and volume, the need to process and interpret all the data has made image processing and computer vision increasingly important. Sources of data that have to be routinely dealt with today's applications include video transmission, wireless communication, automatic fingerprint processing, massive databanks, non-weary and accurate automatic airport screening, robust night vision, just to name a few. Multidisciplinary inputs from other disciplines such as physics, computational neuroscience, cognitive science, mathematics, and biology will have a fundamental impact in the progress of imaging and vision sciences. One of the advantages of the study of biological organisms is to devise very different type of computational paradigms by implementing a neural network with a high degree of local connectivity. This is a comprehensive and rigorous reference in the area of biologically motivated vision sensors. The study of biologically visual systems can be considered as a two way avenue. On the one hand, biological organisms can provide a source of inspiration for new computational efficient and robust vision models and on the other hand machine vision approaches can provide new insights for understanding biological visual systems. Along the different chapters, this book covers a wide range of topics from fundamental to more specialized topics, including visual analysis based on a computational level, hardware implementation, and the design of new more advanced vision sensors. The last two sections of the book provide an overview of a few representative applications and current state of the art of the research in this area. This makes it a valuable book for graduate, Master, PhD students and also researchers in the field.

Although often used in everyday speech and in the scholarly literature, “selective attention” and “consciousness” lack clear, undisputed definitions. Partly because of this deficit there exists a lively debate on the relationship between the two. Nevertheless, attention has been studied scientifically for a long time, because a variety of tasks allow researchers to control several of its aspects (e.g. focused and feature-based attention). Consciousness as a scientific subject of study has emerged more recently, but is now rapidly gaining traction. Scientific studies of consciousness concern the state or level of consciousness (e.g., awake as opposed to in coma, dreamless sleep or under anaesthesia) as well as the contents of consciousness or the phenomenology of perception. With the increase in consciousness-focused research, there is a concomitant surge in research examining the relationship between attention and consciousness. This relationship between attention and consciousness is the topic of this Research Topic. Contributions related to or focused solely on attention or on consciousness will not be considered. It had long been assumed that attention and consciousness are inextricably intertwined: two sides of the same coin. However, recently substantial evidence has emerged that attention and consciousness are interacting, but separable processes. It is however debated how tight the interactions are, and what the exact nature of the relationship is. Therefore, we invite researchers from different “camps” to provide opinionated but balanced literature reviews. Different groups will interpret the same data in different ways. We feel that combining these views in one Research Topic is immensely valuable to researchers from different fields. Apart from reviews we also invite potential contributors to provide new and exciting evidence in the form of original contributions that may support any of the different views. Even though attention and consciousness are critical aspects of many different cognitive processes, they are mainly studied (though not exclusively) in the domain of visual perception. In other sensory modalities, e.g. olfaction or audition, it is currently not clear whether distinctions between attention and consciousness exist, which is even more true for other cognitive processes such as memory. Therefore, we specifically invite contributions covering the auditory, somatosensory, olfactory, and memory domain. We ask all contributors to provide discussions on the relationship between attention and consciousness, and focus on (1) the influence of attention on sensory processing; (2) the formation of conscious perception, (3) the evidence for unconscious processing and its modulation by attention; (4) potential indications for dissociations between attention and consciousness (e.g. does paying attention to a stimulus decrease performance on e.g. a discrimination task?); (5) neuroimaging and neurophysiology data pertaining to these questions. Often, one is caught in one’s own research field and lacks the time or the knowledge to delve into another field. This Research Topic should provide a great overview in great breadth of the current state of knowledge on the links between attention and consciousness, and their interactions, in several different sensory modalities.

In six parts, this book considers the extent to which computational, neural, and ecological constraints have shaped the mechanisms underlying motion vision: - Early Motion Vision - Motion Signals for Local and Global Analysis - Optical Flow Patterns - Motion Vision in Action - Neural Coding of Motion - Motion in Natural Environments Each topic is introduced by a keynote chapter which is accompanied by several companion articles. Written by an international group of experts in neurobiology, psychophysics, animal behaviour, machine vision, and robotics, the book is designed to explore as comprehensively as possible the present state of knowledge concerning the principal factors that have guided the evolution of motion vision.
