Unsupervised Variational Posterior Learning for Mosaic-Based Hyperspectral Fusion Imaging.
Snapshot hyperspectral imaging based on a spectral filter array (SFA) enables high-speed acquisition but inherently trades spatial resolution for spectral resolution. Fusing a low-resolution (LR) mosaiced image with a high-resolution (HR) panchromatic (PAN) image offers a promising solution, yet existing methods often...
