Exploring structural regularities for robust 3D reconstruction of urban scenes
… the problem of inferring 3D structures of urban scenes from 2D images has recently drawn a lot of interest in the computer vision community. Despite the extremely rich literature in multiple view geometry and structure from motion (SFM), reconstructing large-scale high-quality 3D urban …

Medial Prefrontal Cortex fNIRS Activity while Viewing Nature and Urban Scenes: The Search for Neurological Evidence of Nature's Transcendent Self-Diminishment Effect
… by image types. Six were entirely natural scenes (three pleasant and three unpleasant), and six were entirely urban scenes (three pleasant and three unpleasant). After each image block participants took a brief questionnaire to measure their level of immersion. A Flanker task was used to …

Contesting the Secular and Converting Space in Berlin? Becoming Jewish in an Urban Scene.
… of ‘becoming Jewish’ and their impact on this urban scene. In the framework of urban scenes, diaspora and secularism, I describe transformations towards new forms of urban (religious) socialities and aesthetics (music) and show how biographical research and the study of urban scenes offer …

Mind-craft: Exploring the relation between "digital" visual experience and orientation in visual contour perception
… is the orientation anisotropy typical of natural scenes; most natural scenes contain slightly more horizontal and vertical information than oblique information. This property is likely a primary cause of the “oblique effect” in visual perception, in which subjects experience greater perceptual …

Low-rank Based Algorithms for Rectification, Repetition Detection and De-noising in Urban Images
… and repeated patterns detection on 2D urban images, using novel low-rank based techniques. Repeated patterns (such as windows, tiles, balconies and doors) are prominent and significant features in urban scenes.</p> <p>Detection of the periodic structures is useful in many applications …

Analysis of photogrammetrically-derived digital surface and terrain models for building recognition
… frequently occurring man-made objects and in urban scenes their detection and reconstruction, e.g., in the form of three-dimensional CAD (computer aided design) models, is very important to many users such as architects, town planners and telecommunications and environmental engineers. This …

Multispectral Image Labeling for Unmanned Ground Vehicle Environments
… includes common materials present in rural and urban scenes such as vehicles, standing water, various forms of vegetation, and concrete. Experiments are conducted to explore the data requirement for a desired performance and the selection of a hyper-parameter for the textural features. A …

Statistical methods for 2D-3D registration of optical and LIDAR images
… which exploits statistical dependencies in urban scenes, using variables such as LIDAR elevation, LIDAR probability of detection (pdet), and optical luminance. We employ the well known downhill simplex optimization to infer camera pose parameters. Utilization of OpenGL and graphics hardware …

Urban Industry and Literary Work: The Construction of Authorship in the Victorian Social -Problem Novel, 1845--1866
… social-problem novels as products of an urban, industrial literary culture. Challenging the genre's reputation as a prominently mimetic endeavor of middle-class observers, I argue that the writers I address considered themselves ""authors"" immersed in literary practices and professions. …

Disaster and infrastructure scene understanding
Urban scenes are visually complex as they contain physical objects and their spatial-temporal dynamic processes, including natural disasters and human-centered socio-economic activities. Image-based understanding of urban scenes has been actively pursued in the computer and machine vision …

Designing social identities : a case study of a primary school theatrical performance by Zulu children in an English ex-model C school
… fields of home, school, traditional settings and urban settings. The study is qualitative in nature, with the performance text being a participatory, creative, multi modal, joint-construction involving the participants and the researcher. The performance was structured so that each scene …

Aerial reconstructions via probabilistic data fusion
… a 3D photo-realistic model of a given scene. In urban environments, these reconstructions have many applications, such as surveillance, and urban planning. The proposed probabilistic model can be viewed as a data fusion model, in which the two data sources complement each other and allow for …

Feature Extraction Workflows for Urban Mobile-Terrestrial LiDAR Data
… space that was scanned, or not, in an urban scene. It offers new avenues for quality assessment of MTL survey of urban environments by explicitly displaying gaps in data coverage. A number of techniques for navigating and visualizing data from a sensor-perspective are examined. A novel …

A Working Life
… worn or the tools being used. On the surface, urban scenes may convey a gentle flow and constant motion, which are characteristics of an ordered society. Beneath the visible elements are relationships which may represent a vastly different perspective. The work of artists often outlives the …

Low level and intermediate level vision in aerial images
… in the scene domain of aerial images of urban scenes containing man-made structures. The techniques used are based on a common structural and statistical model of the image data. This model assumes that the image data is adequately represented locally by a bivariate cubic polynomial plus …

Large-scale probabilistic aerial reconstruction
… these models enable complex reasoning about urban scenes by fusing all available data across modalities, a crucial necessity for future autonomous agents and large-scale augmented-reality applications.

Learning to super-resolve images using self-similarities
… containing geometric regularities such as in urban scenes, cityscapes etc. We do so by extracting planar surfaces and their parameters (mid-level cues) from the scene and exploiting the detected scene geometry for better guiding the self-similarity search process. Apart from the above …
