region_interface_areas(regions, areas, voxel_size=1, strel=None)¶
Calculates the interfacial area between all pairs of adjecent regions
regions (ND-array) – An image of the pore space partitioned into individual pore regions. Note that zeros in the image will not be considered for area calculation.
areas (array_like) – A list containing the areas of each regions, as determined by
region_surface_area. Note that the region number and list index are offset by 1, such that the area for region 1 is stored in
voxel_size (scalar) – The resolution of the image, expressed as the length of one side of a voxel, so the volume of a voxel would be voxel_size-cubed. The default is 1.
strel (array_like) – The structuring element used to blur the region. If not provided, then a spherical element (or disk) with radius 1 is used. See the docstring for
mesh_regionfor more details, as this argument is passed to there.
areas – A named-tuple containing 2 arrays.
connsholds the connectivity information and
areaholds the result for each pair.
connsis a N-regions by 2 array with each row containing the region number of an adjacent pair of regions. For instance, if
conns[0, 0]is 0 and
conns[0, 1]is 5, then row 0 of
areacontains the interfacial area shared by regions 0 and 5.
