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.

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 book proposes a complete pipeline for monocular (single camera) based 3D mapping of terrestrial and underwater environments. The aim is to provide a solution to large-scale scene modeling that is both accurate and efficient. To this end, we have developed a novel Structure from Motion algorithm that increases mapping accuracy by registering camera views directly with the maps. The camera registration uses a dual approach that adapts to the type of environment being mapped.In order to further increase the accuracy of the resulting maps, a new method is presented, allowing detection of images corresponding to the same scene region (crossovers). Crossovers then used in conjunction with global alignment methods in order to highly reduce estimation errors, especially when mapping large areas. Our method is based on Visual Bag of Words paradigm (BoW), offering a more efficient and simpler solution by eliminating the training stage, generally required by state of the art BoW algorithms.Also, towards developing methods for efficient mapping of large areas (especially with costs related to map storage, transmission and rendering in mind), an online 3D model simplification algorithm is proposed. This new algorithm presents the advantage of selecting only those vertices that are geometrically representative for the scene.
Networked 3D virtual environments allow multiple users to interact with each other over the Internet. Users can share some sense of telepresence by remotely animating an avatar that represents them. However, avatar control may be tedious and still render user gestures poorly. This work aims at animating a user s avatar from real time 3D motion capture by monocular computer vision, thus allowing virtual telepresence to anyone using a personal computer with a webcam. The approach followed consists of registering a 3D articulated upper-body model to a video sequence. The first contribution of this work is a method of allocating computing iterations under real-time constrain that achieves optimal robustness and accuracy. The major issue for robust 3D tracking from monocular images is the 3D/2D ambiguities that result from the lack of depth information. As a second contribution, this work enhances particle filtering for 3D/2D registration under limited computation constrains with a number of heuristics, the contribution of which is demonstrated experimentally. A parameterization of the arm pose based on their end-effector is proposed to better model uncertainty in the depth direction.

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.
Many applications of video technology require multi-target tracking, for example for indoor or outdoor surveillance, intelligent vehicles, robotics, or experiments in biology. This book shows how specifica of targets influence the design of tracking methods. Four totally different types of targets are tracked, namely fruit flies (drosophila melanogaster), vehicles, pedestrians, and lane marks. The book presents methods for tracking of such targets under various recording settings (i.e. static, or moving cameras, monocular, binocular, or trinocular). In order to further improve the tracking performance, more specific methods are proposed and discussed for the different targets. This book starts with a comprehensive review of state-of-the-art multi-traget tracking methods. It is suitable for students or researchers who would like to have advise about tracking methods possibly applicable to their application, or who are contributing in the computer vision field to the design of tracking methods.
