Paint nD¶
Display a 4D labels layer and paint only in 3D.
This is useful e.g. when proofreading segmentations within a time series.
import numpy as np
from skimage import data
import napari
blobs = np.stack(
[
data.binary_blobs(
length=128, blob_size_fraction=0.05, n_dim=3, volume_fraction=f
)
for f in np.linspace(0.05, 0.5, 10)
],
axis=0,
)
viewer = napari.view_image(blobs.astype(float), rendering='attenuated_mip')
labels = viewer.add_labels(np.zeros_like(blobs, dtype=np.int32))
labels.n_edit_dimensions = 3
labels.brush_size = 15
labels.mode = 'paint'
labels.n_dimensional = True
if __name__ == '__main__':
napari.run()
