The Robust Description of the Pore Space

 

 

The discretized pore space is systematically analyzed  for connectivity and geometry by inscribing into each voxel a maximum sphere, and linking these spheres into objects that characterize pore bodies and throats. 

The volumetric and geometric information is processed simultaneously, and no information is discarded.

The result does not depend on the starting point, therefore, the image can be processed by parts

This algorithm is vastly superior to the various medial axis algorithms

 

 

Discrete spheres (left and right) look differently from the analytic one (the middle)

Discretized pore bodies (upper right) and pore throats (lower right) of a sphere pack misaligned on purpose with the principal axes of the image.  Compare these computer-generated images with those in early experimental papers in the 1930's
