Multispectral Image Super-Resolution with $\ell_{1,2}$-Norm Regularization of Spatially-Aligned Laplacians
Abstract
In quest for high spectral fidelity in spatial superresolution of multispectral images, we explore physically-induced, joint spectral-spatial sparsities. The bichromatic image formation model is used to reveal that the discontinuities of a multispectral image tend to align spatially across different spectral bands; in other words, the 2D Laplacians of different bands are not only sparse but also agree with one the other in positions of …
