The 4th International Visual Field Symposium of the International Perimetric Society, was held on the 13-16 April 1980 in Bristol, England,at the occasion of the 6th Congress of the European Society of Ophthalmology. The main themes of the symposium were comparison of classical perimetry with visual evoked response, comparison of classical perimetry with special psychophysi cal methods, and optic nerve pathology. Understandably many papers dealt with computer assisted perimetry. This rapidly developing subgroup of peri metry may radically change the future of our method of examination. New instruments were introduced, new and exciting software was proposed and the results of comparative investigations reported. There have been many confusing statements in the literature on the relative value of perimetry and the registration of visual evoked responses. Several reports attempted to bring some clarity in this issue. There is reason for further comparative research. A number of papers dealt with special psychophysical methods, i.e. methods not using the simply monocular differential threshold. The old critical fusion frequency received new attention. Fundusperimetry was used for testing spatial summation. Acuity perimetry, binocular perimetry etc. showed that there exist many possibilities for examining visual function. At present it is not clear to us what exactly the place of these methods is in our diagnostic armament. However it is quite clear that some of them are promising and may lead to a further differentiation of perimetric methods.
Essay from the year 2010 in the subject Philosophy - Practical (Ethics, Aesthetics, Culture, Nature, Right, ...), grade: 1,0, University of St Andrews, language: English, abstract: Already in ancient times the image of the Other was negatively connoted with the Foreign imagined as a monster creature, dog-headed or monocular, which has manifested itself in the opposition of the 'civilised' and the 'primitive world'. This construct helps integrate the foreign reality into the own cultural horizon of knowledge. This builds the starting point for the thesis of this essay that suggests that only through the unprejudiced encounter with the Other can the Self truly be. The idea derives from Kant's theory that claims that in order to be ourselves we need to combine with other people (Wohlgemut 2009). Therefore, what is attempted in this essay is to analyse the process of self-awareness in Maria Edgeworth's Ennui (1809), Lady Morgan's The Wild Irish Girl (1806) and in Levinas's The Trace of the Other (1986). In his philosophy of encounter, Levinas promotes the devotion to the Other. For him, the key to ethical commitment lies in the encounter with the Other. As will be shown in the course of this essay, the two discussed Irish national tales develop their narrative around this philosophy of encountering the Other that brings about self-awareness. To set a ground for the analysis, chapter two is dedicated to explore the phenomenon of mythisising the Other. Subsequently, chapter three shall analyse in what way Edgeworth, Lady Morgan and Levinas promote the shedding of the myths that develop around representing the Foreign. The process of overcoming cultural borders shall be looked at in more detail in chapter four. Furthermore, chapter five shall elucidate the national characters displayed in the Irish tales and contrast them to Levinas philosophy. Lastly, chapter six will conclude the essay in a retrospective analysis.
This book summarises the state of the art in computer vision-based driver and road monitoring, focussing on monocular vision technology in particular, with the aim to address challenges of driver assistance and autonomous driving systems.While the systems designed for the assistance of drivers of on-road vehicles are currently converging to the design of autonomous vehicles, the research presented here focuses on scenarios where a driver is still assumed to pay attention to the traffic while operating a partially automated vehicle. Proposing various computer vision algorithms, techniques and methodologies, the authors also provide a general review of computer vision technologies that are relevant for driver assistance and fully autonomous vehicles.Computer Vision for Driver Assistance is the first book of its kind and will appeal to undergraduate and graduate students, researchers, engineers and those generally interested in computer vision-related topics in modern vehicle design.
Vision-based control of wheeled mobile robots is an interesting field of research from a scientific and even social point of view due to its potential applicability. This book presents a formal treatment of some aspects of control theory applied to the problem of vision-based pose regulation of wheeled mobile robots. In this problem, the robot has to reach a desired position and orientation, which are specified by a target image. It is faced in such a way that vision and control are unified to achieve stability of the closed loop, a large region of convergence, without local minima and good robustness against parametric uncertainty. Three different control schemes that rely on monocular vision as unique sensor are presented and evaluated experimentally. A common benefit of these approaches is that they are valid for imaging systems obeying approximately a central projection model, e.g., conventional cameras, catadioptric systems and some fisheye cameras. Thus, the presented control schemes are generic approaches. A minimum set of visual measurements, integrated in adequate task functions, are taken from a geometric constraint imposed between corresponding image features. Particularly, the epipolar geometry and the trifocal tensor are exploited since they can be used for generic scenes. A detailed experimental evaluation is presented for each control scheme.
High Quality Content by WIKIPEDIA articles! High Quality Content by WIKIPEDIA articles! The lightweight helmet is the U.S. Marine Corps replacement for the PASGT combat helmet. As it is nearly identical to untrained eyes in shape to the PASGT, it is still called the "Fritz helmet" or "K-pot". Though heavier than the Army's advanced combat helmet, its larger size also offers more protection and is lighter than the PASGT. Featuring a V-neck strap and improved fit, it is much more comfortable than the PASGT. It entered service in late 2004 and will completely replace the PASGT by 2009. As with the PASGT helmet, it is an olive drab color, and can be fitted with cloth helmet covers in desert and woodland MARPAT camouflage patterns, as well as a mounting bracket on the front for any sort of night vision device, such as the AN/PVS-7 night vision goggle or AN/PVS-14 monocular night vision device. Marines currently can be issued with a sling suspension or a pad suspension to fit the inside of the helmet to the head. A nape protection system to add ballistic protection to the rear of the head is also being fielded.
Simultaneous Localization and Mapping, comprising estimation of robot ego-motion and building a map of the surrounding environment, is one of the most fundamental tasks of mobile robotics. Many SLAM systems proposed in the past make use of the Global Positioning System (GPS), which renders them both expensive and overly dependent on the presence of the GPS signal. We propose an alternative, low-cost approach for portable SLAM which is based on monocular vision, a promising technique due to its flexibility, ease of use, and ease of calibration. In order to perform this task we use an Extended Kalman Filter, one of the most efficient and robust methods used in SLAM systems. We show how it is possible to improve the estimated position and reduce its uncertainty by fusing data from different sensors, in particular using a simple 3-axis accelerometer. We prove, through careful and intelligent selection and tuning of image analysis algorithms, that real-time, low-cost SLAM is feasible. This work is useful to professionals developing SLAM systems and to people in the larger field of computer vision, especially those interested in feature detection and tracking.

This manuscript addresses the problem of obstacle avoidance for semi- and autonomous terrestrial platforms in dynamic and unknown environments. Based on monocular vision, it proposes a set of tools that continuously monitors the way forward, proving appropriate road information in real time. Taking into account the temporal coherence between consecutive frames, a new Dynamic Power Management methodology is proposed and applied to a robotic visual machine perception, which included a new environment observer method to optimize energy consumption used by a visual machine. A remarkable characteristic of these methodologies is its independence of the image acquiring system and of the robot itself. This real-time perception system has been evaluated from different test-banks and also from real data obtained by two intelligent platforms. In semi-autonomous tasks, tests were conducted at speeds above 100 Km/h. Autonomous displacements were also carried out successfully.

An ocular prosthesis or artificial eye (a type of Craniofacial prosthesis) replaces an absent natural eye following an enucleation, evisceration, or orbital exenteration. The prosthetic fits over an orbital implant and under the eyelids. Typically known as a glass eye, the ocular prosthesis roughly takes the shape of a convex shell and is made of medical grade plastic acrylic. A few ocular prosthetics today are made of cryolite glass. A variant of the ocular prosthesis is a very thin hard shell known as a scleral shell which can be worn over a damaged eye. Makers of ocular prosthetics are known as ocularists. An ocular prosthetic does not provide vision, this would be a visual prosthetic. Someone with an ocular prosthetic is totally blind on the affected side and has monocular (one sided) vision which affects depth perception.
Who killed Nanna Birk Larsen? Through the dark wood where the dead trees give no shelter Nanna Birk Larsen runs…. There is a bright monocular eye that follows, like a hunter after a wounded deer. It moves in a slow approaching zigzag, marching through the Pineseskoven wasteland, through the Pentecost Forest. The chill water, the fear, his presence not so far away... There is one torchlight on her now, the single blazing eye. And it is here.... Sarah Lund is looking forward to her last day as a detective with the Copenhagen Police department before moving to Sweden. But everything changes when nineteen-year-old student, Nanna Birk Larsen, is found raped and brutally murdered in the woods outside the city. Lund’s plans to relocate are put on hold as she leads the investigation along with fellow detective Jan Meyer. While Nanna’s family struggles to cope with their loss, local politician Troels Hartmann is in the middle of an election campaign to become the new mayor of Copenhagen. When links between City Hall and the murder suddenly come to light, the case takes an entirely different turn. Over the course of twenty days, suspect upon suspect emerges as violence and political intrigue cast their shadows over the hunt for the killer. 1. Language: English. Narrator: Christian Rodska.
