porespy.metrics.porosity_by_type(im, conn='min')#

Computes different types of porosity in an image including total, closed, and surface

Parameters:

im (ndarray) – An image of the void space with 1 (or True) representing the phase of interest. The bulk volume will be computed as the sum of 0’s and 1’s.
conn (str) – Can be either ‘min’ or ‘max’ and controls the shape of the structuring element used to determine voxel connectivity. The default if ‘min’ which imposes the strictest criteria, so that voxels must share a face to be considered connected.

Returns:

A dataclass-like object with the following attributes:

Attribute	Description
total	The total fraction of the image which is void phase
closed	The fraction of the image which consists isolated voids
surface	The fracton of the image which are pores only the surfaces

Return type:
