Query: Hyperspectral Super-resolution: A Coupled Nonnegative Block-term Tensor
  Decomposition Approach   Hyperspectral super-resolution (HSR) aims at fusing a hyperspectral image
(HSI) and a multispectral image (MSI) to produce a super-resolution image
(SRI). Recently, a coupled tensor factorization approach was proposed to handle
this challenging problem, which admits a series of advantages over the classic
matrix factorization-based methods. In particular, modeling the HSI and MSI as
low-rank tensors following the {\it canonical polyadic decomposition} (CPD)
model, the approach is able to provably identify the SRI, under some mild
conditions. However, the latent factors in the CPD model have no physical
meaning, which makes utilizing prior information of spectral images as
constraints or regularizations difficult---but using such information is often
important in practice, especially when the data is noisy. In this work, we
propose an alternative coupled tensor decomposition approach, where the HSI and
MSI are assumed to follow the {\it block-term decomposition (BTD)} model.
Notably, the new method also entails identifiability of the SRI under realistic
conditions. More importantly, when modeling a spectral image as a BTD tensor,
the latent factors have clear physical meaning, and thus prior knowledge about
spectral images can be naturally incorporated. Simulations using real
hyperspectral images are employed to showcase the effectiveness of the proposed
approach with nonnegativity constraints.
