skimage2.data.cells3d

skimage2.data.cells3d()

3D fluorescence microscopy image of cells.

The returned data is a 3D multichannel array with dimensions provided in (z, c, y, x) order. Each voxel has a size of (0.29 0.26 0.26) micrometer. Channel 0 contains cell membranes, channel 1 contains nuclei.

Returns:

cells3dndarray of shape (60, 2, 256, 256) and dtype uint16

The volumetric images of cells taken with an optical microscope.

Notes

The data for this was provided by the Allen Institute for Cell Science.

It has been downsampled by a factor of 4 in the row and column dimensions to reduce computational time.

The microscope reports the following voxel spacing in microns:

• Original voxel size is (0.290, 0.065, 0.065).

• Scaling factor is (1, 4, 4) in each dimension.

• After rescaling the voxel size is (0.29 0.26 0.26).
