Building facade detection is an important problem in computer vision, with applications in mobile robotics and semantic scene understanding. In particular, mobile platform localization and guidance in urban environments can be enabled with accurate models of the various building facades in a scene. Toward that end, we present a system for detection, segmentation, and parameter estimation of bui...

Three-dimensional (3-D) modeling of urban environments has numerous applications, including virtual environments, urban planning, and physical simulation. Constructing 3-D models from photographs (images) is thus an important area of research in computer vision, and increasingly, computer graphics. However, despite many years of research, a system that automatically recovers realistic 3-D model...

Extraction of a digital elevation model from high resolution satellite images such as IKONOS is important for many applications. One of the most popular techniques hired for automated DEM extraction is stereo matching. However, high resolution satellite images possess some properties that make automated stereo matching difficult. They present edges of individual buildings, building facades and ...

Data from the Hyperspectral Mapper (HyMap), which is acquired with a field of view (FOV) of 61.3 degrees, is disturbed by the bidirectional behavior of the covered surface and its complex geometry. The resulting phenomena, an across-track brightness gradient and spectral differences caused by shifted objects, were described and analyzed in detail. An appropriate correction method for the object...

Modeling of urban facades from raw LiDAR point data remains active due to its challenging nature. In this paper, we propose an automatic yet robust 3D modeling approach for urban facades with raw LiDAR point clouds. The key observation is that building facades often exhibit repetitions and regularities. We hereby formulate repetition detection as an energy optimization problem with a global ene...

Extracting 3-dimensional structure from real-world imagery and rendering it from unrestricted viewpoints is an important problem in computer vision, and increasingly, computer graphics. Despite many years of research, a system that automatically recovers realistic 3-D models from images remains elusive; most practical systems require signiicant human input. However, unlike automatic algorithms,...

The aim is a cleaning robot which automatically cleans the outside of windows on a facade with vertical jambs and horizontal bars. The facade has to possess certain constructive properties. This "interface" enables the cleaning robot which is detachable from the building and portable to operate on any respectively designed facade on several buildings. A special cleaning-head keeps the water use...

The article is devoted to the collective monograph “War, Politics, Memory: Napoleonic Wars and World War I in Space of Anniversaries”. Prepared by a large team academics under leadership Olga Porshneva, Nikolai Baranov, Vladimir Zemtsov (professors at Ural Federal University), it first generalizing work dedicated historical memory politics surrounding these wars. uses complex documents from arc...
