Digital Surface Model Extraction and Refinement through Image Segmentation – Application to the ISPRS Benchmark Stereo Dataset
VHR satellite images are generally used for this scope, as they almost cover any area of the planet, in particular remotely located areas. To describe the pre-event and post-event scenarios the available data are analysed and eventually fused in order to achieve the most accurate and reliable information. With respect to automatic 3D information extraction, the availability of accurate and deta...
متن کاملDsm Accuracy Evaluation for the Isprs Commission I Image Matching Benchmark
To improve the quality of algorithms for automatic generation of Digital Surface Models (DSM) from optical stereo data in the remote sensing community, the Working Group 4 of Commission I: Geometric and Radiometric Modeling of Optical Airborne and Spaceborne Sensors provides on its website http://www2.isprs.org/commissions/comm1/wg4/benchmark-test.html a benchmark dataset for measuring and comp...
متن کاملOn the Applicability of Deterministic Modelling to Indoor UWB Channels
This paper reports on the results of Ultra-Wideband measurements for several scenarios from 2 GHz to 6 GHz within an office building and investigates the applicability of deterministic modelling through 3D ray tracing to UWB channels. The blind prediction, based on the a priori knowledge of material parameters and on measured antenna radiation patterns, uses a sub-band-divided ray tracing. Meas...
متن کاملsurvey on the rule of the due & hindering relying on the sheikh ansaris ideas
قاعده مقتضی و مانع در متون فقهی کم و بیش مستند احکام قرار گرفته و مورد مناقشه فقهاء و اصولیین می باشد و مشهور معتقند مقتضی و مانع، قاعده نیست بلکه یکی از مسائل ذیل استصحاب است لذا نگارنده بر آن شد تا پیرامون این قاعده پژوهش جامعی انجام دهد. به عقیده ما مقتضی دارای حیثیت مستقلی است و هر گاه می گوییم مقتضی احراز شد یعنی با ماهیت مستقل خودش محرز گشته و قطعا اقتضاء خود را خواهد داشت مانند نکاح که ...
15 صفحه اولCrowdsourced WiFi database and benchmark software for indoor positioning
This dataset contains two Wi-Fi databases (one for training and one for test/estimation purposes in indoor positioning applications), collected in a crowdsourced mode (i.e., via 21 different devices and different users), together with a benchmarking utility software (in Matlab and Python) to illustrate various algorithms of indoor positioning based solely on WiFi information (MAC addresses and ...
