This paper examines the hypothesis that the observable impacts of roads on the environment depend on spatial resolution.
The JFNK method is between 3 and 6.6 times faster (depending on the spatial resolution and termination criterion) than the standard solver using a preconditioned generalized minimum residual method.
Figure 2 PSNR depending on the spatial resolution ratio at various low bitrates obtained with HD-sized Station2 sequence.
The sequence acquisition time on a 1.5-T system ranges from 5 to 8 min, depending on the spatial resolution and the coverage of the brain needed, leading to an increased incidence of movement artefacts.
Different imaging modalities may yield a wide range of results for accuracy regarding the detection of liver metastases, depending on the spatial resolution and the imaging contrast[ 10, 11 ].
The imaging parameters optimized for T1 contrast that were used included the following [ 13]: TR/TE = 938 ms/24 ms; turbo factor = 29; echo spacing = 4.54 ms; iPAT = 2; average = 1.4 (partial averaging); isotropic voxel resolution varied between (0.5 mm) and (0.7 mm), and the average scan time was 8 min (6 10 min, depending on the spatial resolution).
This illustrates the fact that the ability of PET imaging to detect small cancer deposits depends not only on spatial resolution, but also on other factors such as F-FDG avidity and contrast between lesion and background.
The CBD model is uniquely defined by the set of thresholds, generally different for each band, and by the window size N, depending on the spatial resolutions and scale ratio of the images to be merged, as well as on the landscape characteristics, to avoid loss of local sensitivity [40].
The information that is provided by a localization cue depends on its spatial resolution and on the spatial ambiguity in interpreting the cue.
This trade-off can be tuned based on explicit estimation error bounds which depend on the spatial resolution and the Gaussian kernel parameters.
But crucially the detection of such 'hotspots' depended on the spatial resolution of the mapping unit.
