Download or read book The Neurology of Vision written by Jonathan D. Trobe and published by Oxford University Press. This book was released on 2001-03-29 with total page 686 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Neurology of Vision sets out the principles and information needed to understand and manage disorders of the visual pathways in the brain. The author divides vision into three components. The optical component addresses the eye's ability to properly focus light on the retina. The retinocortical component converts light into neural signals in the retina, transmitting them to the primary visual cortex. Finally, the integrative component converts this simple visual information into more complicated forms. The symptoms and signs, testing methods, and diseases of each part of the visual system are presented using this unique, structural component approach. A final chapter discusses the visual manifestations of psychiatric disturbances. The book is heavily illustrated with over 150 beautifully rendered line illustrations, 50 radiographic brain images, and 60 retinal photographs. Case studies with teaching questions are also included, to further the reader's knowledge and test understanding.

Download or read book Neuro optometric Rehabilitation written by William V. Padula and published by . This book was released on 2000 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This is an in-depth study of the various issues that lie at the core of appropriate neuro-optometric rehabilitation. Background material includes the relationship of vision to development; the examination of perception as it is affected by vision impairment; and how function and performance are impacted by the sensory component of the visual process. The next phase of understanding is the relationship between vision, posture and movement. Whether it is attempting to understand the relationship of vision and its influence on posture for a physically-disabled child or, how vision affects posture after a person has suffered a cerebral vascular accident or traumatic brain injury, the developmental nature of vision affecting the sensory motor system is the basis by which one establishes the framework for visual rehabilitation of the neurologically-challenged patient. The final chapters represent new directions in neuro-optometric rehabilitation with emphasis on post-trauma vision syndrome as well as visual midline shift syndrome, a new concept in thinking concerning the sensory distortions that can occur when there is a neurological interference in the sensory-motor system."--Publisher's description.
Download or read book Vision Rehabilitation written by Penelope S. Suter and published by CRC Press. This book was released on 2016-04-19 with total page 544 pages. Available in PDF, EPUB and Kindle. Book excerpt: Providing the information required to understand, advocate for, and supply post-acute vision rehabilitative care following brain injury, Vision Rehabilitation: Multidisciplinary Care of the Patient Following Brain Injury bridges the gap between theory and practice. It presents clinical information and scientific literature supporting the diagnostic and therapeutic strategies applied in a comprehensive overview of current diagnostic and treatment strategies in adult post-brain injury vision rehabilitation. Includes a foreword by Dr. Sue Barry Because post-brain injury rehabilitation works best in a team setting where the entire person can be treated, this text has been carefully designed as a multidisciplinary resource with an emphasis on models for working with the rehabilitation team. The book covers a myriad of topics such as post-brain injury vision rehabilitation; eye movements; binocular dysfunction; visual field loss; visual-spatial neglect; shifts in visual egocenter affecting balance and coordination; visual-vestibular interactions; central vs. peripheral visual attention; as well as deficits in object perception, visual memory, and visual cognition. The book details models that vision specialists working with the rehabilitation team can use to achieve the best success for the patient in rehabilitation; vision rehabilitation concepts and the science from which they have been developed; examples of therapeutic exercises; practice management information for the post-brain injury vision rehabilitation practice; and information on the legal process in which one frequently becomes involved in this type of work. Edited by eminent clinicians, the book highlights the work of contributors who are well-respected academicians and researchers, bringing together the clinical information that enables everyone involved in a brain injury case to grasp the diagnostic and therapeutic strategies.
Download or read book Neurovision Neural bases of binocular vision and coordination and their implications in visual training programs written by Olivier A. Coubard and published by Frontiers Media SA. This book was released on 2015-10-12 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: Binocular vision is achieved by five neurovisual systems originating in the retina but varying in their destination within the brain. Two systems have been widely studied: the retino-tectal or retino-collicular route, which subserves an expedient and raw estimate of the visual scene through the magnocellular pathway, and the retino-occipital or retino-cortical route, which allows slower but refined analysis of the visual scene through the parvocellular pathway. But there also exist further neurovisual systems: the retino-hypothalamic, retino-pretectal, and accessory optic systems, which play a crucial role in vision though they are less understood. The retino-pretectal pathway projecting onto the pretectum is critical for the pupillary or photomotor reflex. The retino-hypothalamic pathway projecting onto the suprachiasmatic nucleus regulates numerous behavioral and biological functions as well as circadian rhythms. The accessory optic system targeting terminal lateral, medial and dorsal nuclei through the paraoptic fasciculus plays a role in head and gaze orientation as well as slow movements. Taken together, these neurovisual systems involve 60% of brain activity, thus highlighting the importance of vision in the functioning and regulation of the central nervous system. But vision is first and foremost action, which makes perception impossible without movement. Binocular coordination is a prerequisite for binocular fusion of the object of interest on the two foveas, thus ensuring visual perception. The retino-collicular pathway is sufficient to elicit reflexive eye movements with short latencies. Thanks to its motor neurons, the superior colliculus activates premotor neurons, which themselves activate motor neurons of the oculomotor, trochlear and abducens nuclei. At a higher level, a cascade of neural mechanisms participates in the control of decisional eye movements. The superior colliculus is controlled by the substancia nigra pars reticulata, which is itself gated by subcortical structures such as the dorsal striatum. The superior colliculus is also inhibited by the dorsolateral prefrontal cortex through a direct prefrontotectal tract. Cortical areas are crucial for the triggering of eye movements: the frontal eye field, supplementary eye field, and parietal eye field. Finally the cerebellum maintains accuracy. The focus of the present research topic, entitled Neural bases of binocular vision and coordination and their implications in visual training programs, is to review the most recent findings in brain imaging and neurophysiology of binocular vision and coordination in humans and animals with frontally-placed eyes. The emphasis is put on studies that enable transfer of knowledge toward visual training programs targeting visual field defects (e.g., hemianopia) and binocular functional disorders (e.g., amblyopia).

It presents the importance of neuro-computing to artificial intelligence, giving historical background and present-day implementation options. The book demonstrates the superiority of the adaptive search strategy over conventional fixed parameter searches performed by backpropagation algorithms. It then explores global optimization strategy and presents genetic algorithms as viable methods to train neuro computers on non-trivial problems. This self-contained volume is delivered in a format that is suitable for graduate students, as well as researchers who want to begin work in neuro-computing or related artificial intelligence applications.
Download or read book Robot Vision written by Ales Ude and published by BoD – Books on Demand. This book was released on 2010-03-01 with total page 628 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of robot vision is to enable robots to perceive the external world in order to perform a large range of tasks such as navigation, visual servoing for object tracking and manipulation, object recognition and categorization, surveillance, and higher-level decision-making. Among different perceptual modalities, vision is arguably the most important one. It is therefore an essential building block of a cognitive robot. This book presents a snapshot of the wide variety of work in robot vision that is currently going on in different parts of the world.
Download or read book What can simple brains teach us about how vision works written by Davide Zoccolan and published by Frontiers Media SA. This book was released on 2015-11-18 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vision is the process of extracting behaviorally-relevant information from patterns of light that fall on retina as the eyes sample the outside world. Traditionally, nonhuman primates (macaque monkeys, in particular) have been viewed by many as the animal model-of-choice for investigating the neuronal substrates of visual processing, not only because their visual systems closely mirror our own, but also because it is often assumed that “simpler” brains lack advanced visual processing machinery. However, this narrow view of visual neuroscience ignores the fact that vision is widely distributed throughout the animal kingdom, enabling a wide repertoire of complex behaviors in species from insects to birds, fish, and mammals. Recent years have seen a resurgence of interest in alternative animal models for vision research, especially rodents. This resurgence is partly due to the availability of increasingly powerful experimental approaches (e.g., optogenetics and two-photon imaging) that are challenging to apply to their full potential in primates. Meanwhile, even more phylogenetically distant species such as birds, fish, and insects have long been workhorse animal models for gaining insight into the core computations underlying visual processing. In many cases, these animal models are valuable precisely because their visual systems are simpler than the primate visual system. Simpler systems are often easier to understand, and studying a diversity of neuronal systems that achieve similar functions can focus attention on those computational principles that are universal and essential. This Research Topic provides a survey of the state of the art in the use of animal models of visual functions that are alternative to macaques. It includes original research, methods articles, reviews, and opinions that exploit a variety of animal models (including rodents, birds, fishes and insects, as well as small New World monkey, the marmoset) to investigate visual function. The experimental approaches covered by these studies range from psychophysics and electrophysiology to histology and genetics, testifying to the richness and depth of visual neuroscience in non-macaque species.
Download or read book Computer Vision Systems written by Antonios Gasteratos and published by Springer. This book was released on 2008-05-09 with total page 561 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past few years, with the advances in microelectronics and digital te- nology, cameras became a widespread media. This, along with the enduring increase in computing power boosted the development of computer vision s- tems. The International Conference on Computer Vision Systems (ICVS) covers the advances in this area. This is to say that ICVS is not and should not be yet another computer vision conference. The ?eld of computer vision is fully covered by many well-established and famous conferences and ICVS di?ers from these by covering the systems point of view. ICVS 2008 was the 6th International Conference dedicated to advanced research on computer vision systems. The conference, continuing a series of successful events in Las Palmas, Vancouver, Graz, New York and Bielefeld, in 2008 was held on Santorini. In all, 128 papers entered the review process and each was reviewed by three independent reviewers using the double-blind review method. Of these, 53 - pers were accepted (23 as oral and 30 as poster presentation). There were also two invited talks by P. Anandan and by Heinrich H. Bultho ̈ ?. The presented papers cover all aspects of computer vision systems, namely: cognitive vision, monitor and surveillance, computer vision architectures, calibration and reg- tration, object recognition and tracking, learning, human—machine interaction and cross-modal systems.
Download or read book Intelligent active vision systems for robots written by Erik Valdemar Cuevas Jiménez and published by Cuvillier Verlag. This book was released on 2007-01-08 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this paper, an active vision system is developed which is based on image strategy. The image based control structure uses the optical flow algorithm for motion detection of an object in a visual scene. Because the optical flow is very sensitive to changes in illumination or to the quality of the video, it was necessary to use median filtering and erosion and dilatation morphological operations for the decrease of erroneous blobs residing in individual frames. Since the image coordinates of the object are subjected to noise, the Kalman filtering technique is adopted for robust estimation. A fuzzy controller based on the fuzzy condensed algorithm allows real time work for each captured frame. Finally, the proposed active vision system has been simulated in the development/simulation environment Matlab/Simulink.

VISUAL COMMUNICATION An Information Theory Approach Chapter 1 Introduction 1. 1 OBJECTIVE l The fundamental problem of communication, as Shannon stated it, is that of reproducing at one point either exactly or approximately a message selected at another point. In the classical model of communication (Fig. 1. 1), the infor mation source selects a desired message from a set of possible messages which the transmitter changes into the signal that is actually sent over the commu nication channel to the receiver. The receiver changes this signal back into a message, and hands this message to the destination.
