porespy.filters.find_invalid_pores

porespy.filters.find_invalid_pores(im: numpy.typing.NDArray, axis=None, conn: Literal['max', 'min'] = 'min')

Finds invalid pores which are either closed or do not span the domain

Parameters:

• im (ndarray) – A boolean array with True indicating the phase of interest

• axis (int) – The direction which defines the surfaces of interest. By default all directions are considered.

• 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:

invalid – A array containing 1 indicated closed pores and 2 indicating surface pores.

Return type:

ndarray
