Principles of Deterministic Spatial Interpolators

چکیده
Resumo: A interpolação espacial é o processo de prever o valor de atributos em locais não amostrados a partir de medições realizadas em localizações diversas de uma determinada região [Burrough, McDonnell, 1998]. Rever e comparar os interpoladores determinísticos espaciais usados em Sistemas de Informação Geográficos (GIS) como a B-Spline, Fourier, TIN, IDW e as superfícies de tendência polinomiais é o objectivo principal deste artigo curto. Alguns aspectos técnicos computacionais são igualmente examinados.

Improved nearest neighbor interpolators based on confidence region in medical image registration
In order to reduce artifacts in match metric and improve the registration speed in medical image registration, three types of improved nearest neighbor (NN) interpolators based on confidence region (CR) are studied. These improved NN interpolators include: (1) NN based on deterministic confidence region (DCR), DCRNN; (2) NN based on stochastic confidence region (SCR), SCRNN; (3) NN based on con...
متن کاملThe Deterministic Generation of Extreme Surface Water Waves Based on Soliton on Finite Background in Laboratory
This paper aims to describe a deterministic generation of extreme waves in a typical towing tank. Such a generation involves an input signal to be provided at the wave maker in such a way that at a certain position in the wave tank, say at a position of a tested object, a large amplitude wave emerges. For the purpose, we consider a model called a spatial-NLS describing the spatial propagation o...

Accurate knowledge of spatial distribution of soil physical and chemical properties is needed for suitable management and proper use of rangelands in Masileh plain, Qom, Iran. In present study, for the spatial modeling of chemical and physical parameters such as sodium (Na), calcium (Ca), soluble potassium (K), magnesium (Mg), Electrical Conductivity (EC), Saturation Percentage (SP%), silt, cla...
متن کاملUsing geostatistical and deterministic modelling to identify spatial variability of groundwater quality
The main portion of water demands of arid regions like Kashan Plain, Iran supply by groundwater wells. This research was conducted to assess the groundwater quality as well as modelling and mapping groundwater quality in the study area using geosatistics and deterministic techniques. Five water quality parameters, including Electrical Conductivity, Sodium Adsorption Ratio, Total Hardness, ...
متن کاملComparison of Deterministic and Geomorphic Methods for Determining Spatial Variations of Nitrate in Ghaemshahr-Juybar Plan
Nitrate is one of the most important pollutants of surface water and underground water resources which has adverse effects on the health of consumers. Due to lack of sufficient opportunity and budget, in practice, full and timely sampling of all wells in each area is not possible. So the amount of nitrate in certain parts according to the adjacent groundwater is of particular importance in...
