Organs, cells in organs and microstructures in cells are mathematically spatial textures. Tensors allow us to directly analyse, manipulate and recognise such volumetric data in medical image computing. Tensor-based data expression provides a classification method for temporal morphogenesis of spatiotemporal volumetric sequences using geodesic distances between tensor subspaces. Geodesic measures are introduced both for the Grassmann and Stiefel manifolds in multilinear space. Experimental evaluations of cardiac MRI dataset for 17 patients show the validity of the method for discrimination and classification.
