FIGURE 3.6 Illustration of the difference between image and image interpolation.
I and J is assumed to be the same as that represented by I. Obviously, direct stacking
results in unrealistic microstructural features on the transverse sections and will lead
to complicated formulations in feature abstraction computations such as the computa-
tion of stereology-based fabric tensors. Therefore, it is imperative to interpolate be-
tween the sectional images to provide smooth transitions and inherent connections
between the images.
