borders
¶
Generate borders around an image
import matplotlib.pyplot as plt
import numpy as np
import porespy as ps
import inspect
inspect.signature(ps.generators.borders)
<Signature (shape, thickness=1, mode='edges')>
shape
¶
Will typically be the shape of another image, which can be 2D or 3D:
im = ps.generators.blobs([20, 20], porosity=0.6)
bd = ps.generators.borders(shape=im.shape)
fig, ax = plt.subplots(1, 1, figsize=[6, 6])
ax.imshow(bd, interpolation='none')
ax.axis(False);

thickness
¶
Controls the thickness of the border:
im = ps.generators.blobs([20, 20], porosity=0.6)
bd = ps.generators.borders(shape=im.shape, thickness=3)
fig, ax = plt.subplots(1, 1, figsize=[6, 6])
ax.imshow(bd, interpolation='none')
ax.axis(False);

mode
¶
The type of borders to generate, with options being corners
, edges
and faces
. In 2D edges
and corners
are the same.
fig, ax = plt.subplots(1, 3, figsize=[12, 6])
bd = ps.generators.borders(shape=im.shape, thickness=3, mode='faces')
ax[0].imshow(bd, interpolation='none')
ax[0].axis(False)
bd = ps.generators.borders(shape=im.shape, thickness=3, mode='edges')
ax[1].imshow(bd, interpolation='none')
ax[1].axis(False)
bd = ps.generators.borders(shape=im.shape, thickness=3, mode='corners')
ax[2].imshow(bd, interpolation='none')
ax[2].axis(False);

im = ps.generators.blobs(shape=[10, 10, 10], porosity=0.6)
bd = ps.generators.borders(shape=im.shape, thickness=3, mode='edges')
ax = plt.figure().add_subplot(projection='3d')
ax.voxels(bd, edgecolor='k', linewidth=0.25);

im = ps.generators.blobs(shape=[15, 15, 15], porosity=0.6)
bd = ps.generators.borders(shape=im.shape, thickness=3, mode='corners')
ax = plt.figure().add_subplot(projection='3d')
ax.voxels(bd, edgecolor='k', linewidth=0.25);
