Obviously, in practical cases there is not the nice 
consistent 3 * 3 pattern of image points of Figure 2, but 
a less repeatable arrangement.

In these cases we can segment the image into a grid of 
Differences are then formed between the image points in REV 
corresponding meshes. In the presence of "empty" meshes, 
that are meshes without measured points, we form 
differences to the next, nearest meash containing image 
points. sol
