Scene interpretation systems are often conceived as extensions of low-level image analysis with bottom-up processing for high-level interpretations. In this paper we show how a generic high-level interpretation system can generate hypotheses and start top-down analysis. This allows for spatially focussed and specifically parametrised image analysis steps. Experimental results of the recognition...

A virtual 3-dimension city model is a sophisticated application of geoinformatic systems as it represents layouts, activities and functionalities of a real-world community. To enable human users to better visualize their living spaces, a virtual reality city model must be both immersive and accurately re-created. Visualization of city models in such environments is a combination of many challen...

Reducing energy consumption of residential and commercial buildings is a major challenge nowadays. One of the strategies to achieve a significant reduction lies on building renovation. On this regard, a project targeting the industrialization of high performance thermal renovation for apartment buildings is been executed. The renovation is based on an external envelop composed by rectangular wo...

Objective: Bipolar disorder is a severe mental disorder, and its prevalence is around 1% to 2%. Despite a vast literature around bipolar disorder, the reasons of its nonadherence and rehospitalization is still obscure. Several symptoms of bipolar disorder include changes in activity level, cognitive abilities, speech, and vegetative functions, such as sleep, sexual activity, as well as aggressi...

In this paper we present a practical approach for generating an occlusion-free textured 3D map of urban facades by the synergistic use of terrestrial images, 3D point clouds and area-based information. Particularly in dense urban environments, the high presence of urban objects in front of the facades causes significant difficulties for several stages in computational building modeling. Major c...

Corner lines, line signatures related to building facades in SAR images, are commonly related to signal double reflections, either specular or diffuse. However, the scene properties building orientation, building shape, surface roughness often do not correspond to this expectation. This paper presents a 3D representative simulation case study, based on ray tracing and a detailed facade model, i...

Three dimensional building models have become important during the past years for visualization of touristic or historic objects. Detailed facade models are essential for realistic impressions on a terrestial observer. Such models require both a geometric component that describes the shape of the building or parts of it as well as a texture component that provides color information and depicts ...

We examine a new method of façade segmentation in a multi-view scenario. A set of overlapping, thus redundant street-side images exists and each image shows multiple buildings. A semantic segmentation identifies primary areas in the image such as sky, ground, vegetation, and façade. Subsequently, repeated patterns are detected in image segments previous labeled as “façade areas” and are applied...

In this study we investigate the release of metallic silver nanoparticles (Ag-NP) from paints used for outdoor applications. A facade panel mounted on a model house was exposed to ambient weather conditions over a period of one year. The runoff volume of individual rain events was determined and the silver and titanium concentrations of 36 out of 65 runoff events were measured. Selected samples...
