find_dt_artifacts

Labels voxels that are closer to the image boundary than to a solid. These are potentially artifacts since solid voxels could potentially lie just beyond the boundary but were cropped.

dt

This function only accepts 1 argument, the distance tranform.

im = ps.generators.blobs(shape=[500, 500])
dt = spim.distance_transform_edt(im)
dt2 = ps.filters.find_dt_artifacts(dt=dt)
fig, ax = plt.subplots(1, 2, figsize=[12, 6])
ax[0].imshow(dt, interpolation='none', origin='lower')
ax[0].axis(False)
ax[1].imshow(dt2/im, interpolation='none', origin='lower')
ax[1].axis(False);
