Our objective is the interpretation of facade images in a top-down manner, using a Markov marked point process formulated as a Gibbs process. Given single rectified facade images, we aim at the accurate detection of relevant facade objects as windows and entrances, using prior knowledge about their possible configurations within facade images. We represent facade objects by a simplified rectang...

A methodology is presented for estimating, at the city scale, the amount of biocide released from facades during rain events. The methodology consists of two elements. First, leaching of a single facade is simulated using a two-region model, one region for the biocide in the facade and the other for that in the flow over the facade surface. In the latter region, water advection moves the biocid...

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...

Marble is a natural material, used in the construction field since antiquity. It has always been used to communicate monumentality and solidity. Nowadays new technologies permit marble to express new languages: particularly, translucent marble technology overturns the concept of solidity. The main issue to address is the lack of thermal-energy performance of such a thin stone layer as the only ...

Double-skin green facades using deciduous climbing plants are easy-to-implement construction systems stated to be effective energy-saving tools for buildings during cooling periods. Although the leaf area index (LAI) has been identified as a key parameter characterizing foliar density and, consequently, facade's potential passive tool energy savings, lack of knowledge still remains on this inde...

Due to high point density, accuracy and cost-effectiveness, Terrestrial Laser Scanner (TLS) do have the great advantage of providing the details of building facade as required for the production of realistic 3D city models. Thus, a significant amount of research efforts has been directed towards reconstructing building facade models using TLS data. Most of reconstruction strategies are based on...

1-3 (a): hemispherical tiling used for node acquisition; (b): textured hemispher-1-4 (a): the sweep-plane algorithm; (b): the recovered model (not textured).. . 2-2 (a): the position of the camera (red) and of the facade (white) in the modeled environment. The building in the foreground is projected onto the facade; (b): a color image showing the warped image; (c): the binary corresponding 2-3 ...

Building facade extraction is the primary step in the recognition process in outdoor scenes. It is also a challenging task since each building can be viewed from different angles or under different lighting conditions. In outdoor imagery, regions, such as sky, trees, pavement cause interference for a successful building facade recognition. In this paper we propose a knowledge based approach to ...
