Deconvolution algorithm for 3D STEM-EELS maps with total generalized variation (TGV), non-negativity prior and residual balancing for automated and unbiased parameter choice. The algorithm employs a noise model for scintillation-based CCD detectors, as they are often used in EELS, and considers the binning of the detector to create spectra as well as noise correlations occurring on such detectors.
A detailled derivation and description of the algorithm is provided in:
