Interactive Facades Analysis and Synthesis of Semi-Regular Facades
Urban facades regularly contain interesting variations due to allowed deformations of repeated elements (e.g., windows in different open or close positions) posing challenges to state-of-the-art facade analysis algorithms. We propose a semi-automatic framework to recover both repetition patterns of the elements and their individual deformation parameters to produce a factored facade representat...
متن کاملWindow Detection in Frontal Facades
In this paper, we describe a novel technique to identify and extract windows from a building’s frontal facade. Feature detection in buildings has long been an area of research interest for its applications in 3D city modeling and scene visualization. We utilize a combination of projection profiles, mutual information, and a feature extraction technique (Snake Algorithm). We have found this appr...
متن کاملGrammar-based Encoding of Facades
In this paper we propose a real-time rendering approach for procedural cities. Our first contribution is a new lightweight grammar representation that compactly encodes facade structures and allows fast per-pixel access. We call this grammar F-shade. Our second contribution is a prototype rendering system that renders an urban model from the compact representation directly on the GPU. Our sugge...
متن کاملAutomatic Extraction of Textured Vertical Facades from Pose Imagery Automatic Extraction of Textured Vertical Facades from Pose Imagery
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,...
متن کاملAutomated Cleaning of Windows on Standard Facades
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...
