Assessing vulnerability and potential impacts associated with extreme discharges requires an accurate topographic description in order to estimate the extension of flooded areas. However, in most popu...
Any projection of a 3D scene into a wide-angle image unavoidably results in distortion. Current projection methods either bend straight lines in the scene, or locally distort the shapes of scene obj...
Texture-mapping in close-range photogrammetry focuses mostly on the generation of large-scale projections of 3D surfaces, the most common instance being that of orthoimaging. Today, photogrammetry i...
Human operators use an intuitive procedure of rotating laser scanner point clouds into specific projections when trying to understand the structure of buildings contained in the data. This procedure ...
Suppose we are given a vector f in a class F ⊂ RN, e.g. a class of digital signals or digital images. How many linear measurements do we need to make about f to be able to recover f to within pr...
Can we recover a signal f ∈ RN from a small number of linear measurements? A series of recent papers developed a collection of results showing that it is surprisingly possible to reconstruct certain t...
If an aerial-triangulation (AT) is performed in the National Projection System (NPS), then the conformal map projection (which is the base for the NPS) effects the results of the AT by raising three...
As is well known, the projection on the plane of a double curved surface is possible only by introducing warping techniques, be these either angular or superficial: the simple execution operation on t...
This paper analyses the climate change projected for the near and distant future in South America using MRI/JMA (Japanese Meteorological Agency) global model simulations with resolutions of 20 and 60 ...
Projections of the number, rate and cost of fall-related hospitalised injuries for individuals aged 65 years and older in New South Wales (NSW), Australia were estimated to 2051 for two scenarios: (1)...
The IAEA has released the latest update of its annual projections for the future of nuclear power, and both its low and high projections for 2030 are higher than they were last year. The low projectio...
Recently with the development of 3D modeling and digitizing tools, more and more models have been created, which leads to the necessity of the technique of 3D mode retrieval system. In this paper we i...
In this study, a new method is presented, based on genetic algorithms for determining object parameters such as radii and/or attenuation coefficients with some assumptions and estimating a cross-secti...
The paper describes a novel approach for the generation of 3D building models from airborne laserscanner data, which is based on the detection of straight lines in specific 2D projections of the dat...
