In this paper, we propose a top-down building reconstruction technique based on layover modelling and MCMC method. Through representing the layover with parameterized geometrical models, the problem is converted into an optimization problem under the Bayesian scheme. The energy function consists of two parts: region part and edge part. In order to obtain global optima, simulated annealing algorithm...
E-loc is an indoor localization system, which, through using existing indoor electric wiring, detects occupants' location. While many indoor localization technologies require intensive infrastructural supports, E-loc obtain locations by injecting a signal into the protected earth line of existing residential power network. Caused by human body inside a room, the electromagnetic character changes can...
The interferometric coherence map is derived from the cross-correlation of two registered synthetic aperture radar (SAR) images. It can give additional information complementary to the intensity image, or act as an independent information source in many applications. Compared to the plenty of work on SAR intensity statistics, there are quite fewer researches on the statistical characters of interferometric...
In this paper, a fully automatic building reconstruction method for high resolution interferometric synthetic aperture radar (InSAR) data is presented. This method is based on stochastic geometrical model. Firstly, a building detection procedure is implemented on the big image and the entire scene is divided into building clips. After that, the reconstruction process is utilized for each building...
Mining subsidence lead to deform of the earth's surface, which result in different destroy of structure on the earth's surface. Combine damage evaluation of structure in subsidence area with GIS make the damage evaluation scientific, efficient, visual. Damage evaluation system of structure based on ArcGIS 9, which is integrated development system, applies object-oriented visualization programming...
According to the application of secondary water-supply system has been used more and more, the problem of water pollution in secondary water-supply system turns serious. Research was made on distributing rules of bacteria in secondary water-supply system; the variety and correlativity of water quality index were analyzed. Index that reflecting total bacteria number in water-supply system was indicated;...
