Until now, no method for scattered data interpolation with a bivariate function has produced surface formats that can be directly integrated into a CAD system.
In this paper we present a method for scattered data interpolation producing tensor product B-splines with high quality curvature distribution.
We present a method for scattered data approximation with subdivision surfaces which actually uses the true representation of the limit surface as a linear combination of smooth basis functions associated with the control vertices.
To reduce the computational cost, this paper proposes a piece-wise moving least squares approximation method (PMLS) for scattered data approximation.
We develop a highly accurate numerical method for scattering of 3D electromagnetic waves by doubly periodic structures.
The technique combines a previously developed model for noise from disc sources with a boundary integral equation method for scattering from the duct surface.
(a-e) The root mean square error versus SNR by the CoSaMP method and the proposed Bayesian method for scattering coefficient, position in range direction, position in azimuth direction, micromotion frequency and micromotion amplitude, respectively.
Methods for scatter, decay, random, and attenuation correction were applied during the image reconstruction process.
Methods for scatter, decay, random, and attenuation correction were applied during the process of PET image reconstruction.
Of the compensation methods for scatter and septal penetration, a known disadvantage of TEW compared to alternatives such as transmission-dependent convolution subtraction (TDCS) [17] is the increase of Poissonian noise in the projections data.
A computational model of the shielding mechanism has been developed using a combination of boundary integral equation method (BIEM) for source definition and equivalent source method (ESM) for scattering.
