3D data cube

Fiber Bundles Fiber bundles are used for Raman imaging. Several optical fibers are grouped together, each analyzing a specific sample area [13]. A 3D data cube is... 

Given that we have a proper orientation estimate for the 3D data cube (Section 2), measuring flatness is a matter of computing statistics of the orientation field. The flatness can thus be measured as the variance in the orientation field, locally. An example can be seen in Figure 5 (c).
