- region_surface_areas(regions, voxel_size=1, strel=None)¶
Extract the surface area of each region in a labeled image.
Optionally, it can also find the the interfacial area between all adjoining regions.
regions (ndarray) – An image of the pore space partitioned into individual pore regions. Note that zeros in the image will not be considered for area calculation.
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 list containing the surface area of each region, offset by 1, such that the surface area of region 1 is stored in element 0 of the list.
