  • mode (string) –

    Controls the method used. Options are:

    ’marching_cubes’ (default)

    Finds a mesh for each region using the marching cubes algorithm from scikit-image, then finds the volume of the mesh using the trimesh package.

    ’voxel’

    Calculates the region volume as the sum of voxels within each region.
