Let us denote by { b} the reference frame centred in the shoulder and by X, Y, and Z the coordinate axes defining the principal body planes, that is, XY-sagittal, YZ-frontal, and XZ-transverse.
The proposed method begins by finding the reference frame that has the largest well-contrasted region (i.e., smallest saturated region) as in conventional methods [16, 24 26, 29, 30].
In a particular coordinate system, the electric component of random light may fluctuate in three orthogonal spatial directions, but by rotating the reference frame it may turn out that the field vector actually is restricted to a plane, or even that it fluctuates in just a single direction.
Consecutive TSLO frames are broken down into small horizontal strips which are cross-correlated one by one with the reference frame.
Then each consecutive frame is broken down into small strips which are cross-correlated one by one with the reference frame.
Background subtraction attempts to detect moving objects from the difference between the current frame and the reference frame in a pixel-by-pixel or block-by-block fashion.
7 can be transformed onto the reference frame by using the solution for the balance of mass, ρ 0=ρ J, with J= det(F ij ).
This implies a potential bias in the estimated NR metrics induced by the wrong selection of the reference frame to be used for the comparison.
Since there are temporal and spatial relations between two frames, the mapping block (domain block) is often near by the corresponding location in the reference frame of the range block.
The corresponding current angle is δ i0+∆δ i, since the current phase depends on the reference frame provided by the PLL.
