region_volumes

region_volumes(regions, mode='marching_cubes', voxel_size=(1, 1, 1))

Compute volume of each labelled region in an image

Parameters:

• regions (ndarray) – An image with labelled regions

• 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.

Returns:

volumes – An array of shape [N by 1] where N is the number of labelled regions in the image.

Return type:

ndarray
