Sampled values of volumetric data are expressed as three-way array data, which is expressed as tensors. Tensor expression of volumetric images requires quantitative methods for the discrimination of multi-way forms. We define a distance metric for subspaces of multi-way data arrays using transportation between the Stiefel manifolds constructed by subspaces of multi-way data arrays.
