Signature

def cells3d ( )

Summary

3D fluorescence microscopy image of cells.

Extended Summary

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

cells3d : ndarray 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).
