Sentence examples for fourier surface from inspiring English sources
Fig. 1 Fourier surface optimization.
The Fourier surface is gradually adapted to an image object starting from an ellipsoid as initialization.
Voxelization After optimization of the Fourier surface to the object edge, a voxel mask was produced from the interior of the surface.
For images with less noise, for example early imaging time-points in the course of radionuclide therapy dosimetry, an adaptive thresholding algorithm like the Otsu method yields approximately equivalent results as the Fourier surface method.
In Monte Carlo-simulated images a good tumour volume and activity concentration accuracy is obtained for two segmentation methods (Otsu method and Fourier surface method) when images are reconstructed with attenuation and scatter compensation, while if including resolution compensation underestimated volumes and overestimated activity concentrations are obtained.
Initial estimation and optimization Segmentation using Fourier surfaces (FS segmentation) aims to determine appropriate values to the set of Fourier coefficients a, c, and d, for a given number of Fourier orders such that the resulting surface follows the object contour, as reflected in the SPECT image.
Adsorption of the biomolecules was monitored using a quartz crystal microbalance with dissipation (QCM-D) and fourier transform-surface plasmon resonance (FT-SPR).
The results show that for long-times the heat fluxes on the clad surface under Non-Fourier approach can be important, while for short-times and from the engineering point of view the changes are very small.
New near-to-far-field functionality: given a bounding surface, automatically computes the Fourier-transformed field in any desired grid of "far-field" points arbitrarily far away (pull #18).
To study the recorded mechanical response of the beetle's surface quantitatively, we analyze their Fourier spectra in time.
