Whiteness-based bilevel estimation of weighted TV parameter maps for image denoising
Monica Pragliola, Luca Calatroni, Alessandro Lanza
We consider a bilevel optimisation strategy based on normalised residual whiteness loss for estimating the weighted total variation parameter maps for denoising images corrupted by…
