To determine the correct shift, we select the n highest local maxima (3 × 3 × 3 neighborhood) from ℱ−1 and evaluate their eight possible translations by means of cross-correlation on the overlapping area of the images A, B. The peak with the highest correlation is selected as translation between the two images.
The correct shifting of pairs may be accomplished with an automated or manual merging process that, for instance, accounts for the fact that the flux value should be zero when the metabolite concentration is zero.
We can obtain a time shift that is uncontaminated by the shallow-layer reverberation from the cross-correlation of u ij and u ji. Figure 10 shows that the corrected time shifts are almost zero.
In contrast, the corrected model shifted 261 of "intermediate" patients into category "low", thus achieving accurate prediction.
Precision magnetometry is an essential component of any neutron electric dipole moment experiment in order to correct shifts in the neutron precession frequency due to changes in the magnetic field.
Knowing the radial collimator geometry, the geometrical shifts in the peak positions can be predicted, and the shifts corrected for to provide accurate residual strain measurements, even near surface.
While the prediction error validates the results against an external reference (the correct chemical shifts), the uncertainty provides an internal validation.
Unfortunately, the correct time-shifts are undetermined.
Up to now, too few experimentally verified examples of TFs that regulate miRNAs are known, thus a model to introduce the "correct" time-shift could not be inferred.
It is based on the fact that range migration can be corrected by shifting the Doppler slices such that their envelopes are similar, and thus the Doppler centroid can be estimated from the shifting step.
