Claim 6:
7. A system for analyzing a rock sample, comprising:
a scanning electron microscope (SEM) configured to generate two-dimensional (2D) SEM images of physical faces of a rock sample; and
a computing device coupled to the SEM and comprising:
a processor; and
a memory coupled to the processor and configured to store instructions that, when executed by the processor, configure the computing device to:
apply a cross-correlation function to a first 2D SEM image and a second 2D SEM image to generate a three-dimensional (3D) digital model volume based on the first and second 2D SEM images; and
determine a probability distribution of a pore size of the 3D digital model volume based on an image intensity value of a pixel in each of the first and second 2D SEM images.
