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...

The quality of data obtainable by questionnaire from residents of a common lodging house was explored by comparing the answers received by questioning such men on two or three occasions six months apart. Consistency between the answers obtained on different occasions was good for men who already knew the interviewer well as their medical officer but poor otherwise.

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...

What is believed to be the first fluorescence imaging of the facades of a historical building, which was accomplished with a scanning fluorescence lidar system, is reported. The mobile system was placed at a distance of ~60 m from the medieval Lund Cathedral (Sweden), and a 355-nm pulsed laser beam was swept over the stone facades row by row while spectrally resolved fluorescence signals of eac...

Matching street-level images to a database of airborne images is hard because of extreme viewpoint and illumination differences. Color/gradient distributions or local descriptors fail to match forcing us to rely on the structure of self-similarity of patterns on facades. We propose to capture this structure with a novel “scale-selective self-similarity” (S) descriptor which is computed at each ...
