apply_chords_3D(im, spacing=0, trim_edges=True)¶
Adds chords to the void space in all three principle directions. The chords are seprated by 1 voxel plus the provided spacing. Chords in the X, Y and Z directions are labelled 1, 2 and 3 resepctively.
im (ND-array) – A 3D image of the porous material with void space marked as True.
spacing (int (default = 0)) – Chords are automatically separed by 1 voxel on all sides, and this argument increases the separation.
trim_edges (bool (default is
True)) – Whether or not to remove chords that touch the edges of the image. These chords are artifically shortened, so skew the chord length distribution
image – A copy of
imwith values of 1 indicating x-direction chords, 2 indicating y-direction chords, and 3 indicating z-direction chords.
- Return type
The chords are separated by a spacing of at least 1 voxel so that tools that search for connected components, such as
scipy.ndimage.labelcan detect individual chords.
