Intelligent Vehicles for Increasing Driving Safety

Developing on-board driver assistance systems (DAS) requires understanding of various events involving the motions of the vehicles in the vicinity of the host vehicle. Determining the position of other vehicles on the road is a key information to help driver assistance systems. Thus, robust and reliable vehicle detection and tracking are the basic steps in these systems. Since monocular vision based systems are particularly interesting for the advantage of reducing costs and maintenance and for the high fidelity information they give about the driving environment, the problem can be addressed by applying computer vision techniques. This work has mainly been focused on detecting and tracking vehicles viewed from inside a vehicle the camera mounted in daylight conditions. The approach presented in the book uses vehicle shadow clues and vehicle edge information to obtain cost effective and fast estimation. After extracting vehicles, the algorithm effectively track them using a Kalman filter based tracking algorithm. Several sequences from real traffic situations have been tested, obtaining highly accurate multiple vehicle detections.

Stereopsis

High Quality Content by WIKIPEDIA articles! Stereopsis (from stereo meaning solidity, and opsis meaning vision or sight) is the process in visual perception leading to the sensation of depth from the two slightly different projections of the world onto the retinas of the two eyes. The differences in the two retinal images are called horizontal disparity, retinal disparity, or binocular disparity. The differences arise from the eyes' different positions in the head. Stereopsis is commonly referred to as depth perception. This is inaccurate, as depth perception relies on many more monocular cues than stereoptical ones, and individuals with only one functional eye still have full depth perception except in artificial cases (such as stereoscopic images) where only binocular cues are present.

High Quality Content by WIKIPEDIA articles! The visual system is the part of the central nervous system which enables organisms to see. It interprets the information from visible light to build a representation of the world surrounding the body. The visual system accomplishes a number of complex tasks, including the reception of light and the formation of monocular representations, the construction of a binocular perception from a pair of two dimensional projections, the identification and categorization of visual objects, assessing distances to and between objects, and guiding body movements to visual objects. The psychological manifestation of visual information is known as visual perception.

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.

This monograph introduces novel responses to the different problems that arise when multiple robots need to execute a task in cooperation, each robot in the team having a monocular camera as its primary input sensor. Its central proposition is that a consistent perception of the world is crucial for the good development of any multi-robot application. The text focuses on the high-level problem of cooperative perception by a multi-robot system: the idea that, depending on what each robot sees and its current situation, it will need to communicate these things to its fellows whenever possible to share what it has found and keep updated by them in its turn. However, in any realistic scenario, distributed solutions to this problem are not trivial and need to be addressed from as many angles as possible.Distributed Consensus with Visual Perception in Multi-Robot Systems covers a variety of related topics such as:- distributed consensus algorithms,- data association and robustness problems,- convergence speed, and- cooperative mapping.The book first puts forward algorithmic solutions to these problems and then supports them with empirical validations working with real images. It provides the reader with a deeper understanding of the problems associated to the perception of the world by a team of cooperating robots with onboard cameras.Academic researchers and graduate students working with multi-robot systems, or investigating problems of distributed control or computer vision and cooperative perception will find this book of material assistance with their studies.

Visual scene understanding is one of the ultimate goals in computer vision and has been in the field's focus since its early beginning. Despite continuous effort over several years, applications such as autonomous driving and robotics are still subject to active research. In recent years, improved probabilistic methods became a popular tool for state-of-the-art computer vision algorithms. Additionally, high resolution digital imaging devices and increased computational power became available. By leveraging these methodical and technical advancements current methods obtain encouraging results in well defined environments for robust object class detection, tracking and pixel-wise semantic scene labeling and give rise to renewed hope for further progress in scene understanding for real environments. This book improves state-of-the-art scene understanding with monocular cameras and aims for applications on mobile platforms such as service robots or driver assistance for automotive safety. It develops and improves approaches for object class detection and semantic scene labeling and integrates those into models for global scene reasoning which exploit context at different levels.

Asymmetries in visuospatial processing in birds

Research Paper (postgraduate) from the year 2003 in the subject Psychology - Biological Psychology, grade: very good, Ruhr-University of Bochum (AE Biopsychology), course: Experimentalpsychologisches Praktikum, 35 entries in the bibliography, language: English, abstract: Cerebral asymmetries are a fundamental principle of vertebrate brain architecture. These asymmetrical structures are most likely beneficial for various kinds of information processings. Research has shown that the avian brain is highly visually-lateralized. Results display a left hemisphere/right eye advantage in pigeons for object processing. Unfortunately, findings on visuospatial lateralization are ambiguous. In chicks also a left hemisphere dominance for object processing has been shown whereas the right hemisphere is more probable to elicit high performances in visuospatial tasks. Inconsistently, homing pigeons revealed a left-hemispheric superiority for visuospatial orientation. We investigated visuospatial processing in pigeons (Columba livia) with a new experimental paradigm. The subjects were confined in a box with their neck and head protruding through a central circular opening. This opening was surrounded by sixteen concentrically arranged food positions each containing one piece of grain the animals had to peck at. Pigeons were tested alternately under monocular (left/right) and binocular conditions. We measured the time the subjects needed to peck all grains and the extent of visual scanning, operationalized by crossing the circular segments with their head. Although both monocular conditions did not differ with respect to the time needed to finish the task, right-seeing animals needed fewer scans to finish the task. Remarkably, both monocular conditions did not reveal significant differences in number of divers, number of peckfailures and number of direction changes. These findings display a higher efficiency of left hemispheric visuospatial processing. Left-seeing pigeons needed more scans per time than right-seeing birds to consume the grains. In summary, the superiority of the right hemisphere in spatial tasks is not an universal phenomenon of vertebrate brain architecture.
