Frames, the Loewner order and eigendecomposition for morphological operators on tensor fields ?
Loewner order-based maxima/minima are instances of frame-based maxima/minima. Applying a convex function to the eigenvalues of a tensor gives a least upper bound. PDE-based tensor morphology using eigendecomposition is unified with our framework. Most of the results are given for tensors of arbitrary degree.
