porespy.beta.rev_tortuosity

porespy.beta.rev_tortuosity(im, block_sizes=None, use_dask=True)

Generates the data for creating an REV plot based on tortuosity.

Parameters:

• im (ndarray) – The binary image to analyze with True indicating phase of interest

• block_sizes (np.ndarray) – An array containing integers of block sizes to be calculated

• use_dask (bool) – A boolean determining the usage of dask.

Returns:

df – A pandas data frame with the properties for each block on a given row

Attribute	Description
eps_orig	The porosity of the subdomain tested
eps_perc	The porosity of the subdomain tested after filling non-percolating paths
g	The calculated diffusive conductance for the subdomain tested
tau	The calculated tortuosity for the tested subdomain
volume	The total volume of each cubic subdomain tested
length	The length of one side of the subdomain tested
axis	The axis for which the above properties were calculated
time	The elapsed time required to perform the calculations
slice	The coordinates for the subdomain tested in the original image

Return type:

DataFrame
