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...

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 ...

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...

The rapidly growing world energy use has already raised concerns over energy resources and greenhouse gas (GHG) emissions. Since the global contribution from residential buildings towards energy consumption, has steadily increased between 20% and 40% and as large openings have considerable energy and heat loss in dwellings, this paper establishes a coefficient of heat loss and air infiltration ...

Façade fires are of growing concern worldwide. Severe facade in different parts the world as well activities many countries regarding testing facades show urgency fire safety challenges façade fires. The need for knowledge and a wide archive work this area has become evident after recent incidents which involved extensive These include tragic Dubai Grenfell Tower 2017 United Kingdom. In cases, ...
