I am looking at SEM images of sandstones, and would like
to quantify the fractal dimensionality of this surface at this scale.
One way I have thought to do this is to take two or more images,
Tilted relative to one another, to create a stereo pair. From there,
And given the scale of the image, there should be a way to reconstruct
The surface topography as topographic slices or even a digital elevation map.
This could then be used to calculate the "3-D" fractal dimension.
I know this is done for satellite topographic mapping, so it should be do-able
From an SEM image.
Does anyone know if plugins/macros for such a project are available.
Thanks.

P.S. I know from scattering data that, at least at finer scales, these surfaces are fractal.
