Guided Nonlocal Patch Regularization and Efficient Filtering-Based Inversion for Multiband Fusion

no code implementations9 Oct 2022 Unni V. S., Pravin Nair, Kunal N. Chaudhury

In multiband fusion, an image with a high spatial and low spectral resolution is combined with an image with a low spatial but high spectral resolution to produce a single multiband image having high spatial and spectral resolutions.
