Sentence examples for spatially variant from inspiring English sources

For dynamic PET, spatially variant spatial resolution across different time frames can lead to errors on the estimated kinetic parameters.

In this study, we used FBP along with post-reconstruction motion correction rather than iterative reconstruction algorithms to obtain dynamic images because it is well known that iterative reconstruction algorithms, such as OSEM, lead to spatially variant spatial resolution and noise characteristics.

Because of the ill-posedness of the inverse problem, the reconstruction method in fluorescence tomography usually sets up a least square optimization problem minimizing an objective function given by: where λ(r) is a spatially variant regularization parameter to compensate for the spatial dependence of the contrast and resolution in the reconstruction [ 37].

Seamless remote sensing images better represent aggregate exposure than averaging ground measurements over a limited number of monitoring sites, and reduce the problem of spatially variant accuracy in geostatistical interpolation caused by uneven spatial distribution of monitors.

The proposed methods are formulated for the BGK equation with constant or spatially variant Knudsen number.

These joint distributions are in addition spatially variant within the scene frame.

Spatially variant self-collimation is introduced as a powerful means to control the flow of electromagnetic beams along arbitrary paths.

All the spatially variant information of the domain Green's function is collected into the multipole-to-local translations and therefore the FMM becomes heterogeneous.

Therefore, in this study we developed a novel strategy for designing spatially variant filtering parameters which are adaptive to the local characteristics of the image to be reconstructed.

Accurate estimation of df offers many potential advantages for probabilistically thresholding functional connectivity and network statistics tested in the context of spatially variant and non-stationary noise.

Numerical results of synthetic speckle images indicate that the set of algorithm can enhance the accuracy and precision of displacement measurement, especially for spatially variant speckle images.
