I will present our recent work on super-resolution of multiband images with multiresolution bands (e.g., Sentinel-2, MODIS). We address this imaging inverse problem by adopting scene-adapted non-local patch/tensor-based variational regularization. The inference is carried out under the convex or the plug-and-play frameworks. The effectiveness of the proposed approach will be documented in a series of experiments with simulated and real data.
