Learning optimal orders of the underlying Euclidean norm in total variation image denoising

Pan Liu, Carola-Bibiane Schönlieb

A novel class of semi-norms, generalising the notion of the isotropic total variation $T V_{2}$ and the an-isotropic total variation $T V_{1}$ is introduced. A supervised learning me…

Adaptive image processing: a bilevel structure learning approach for mixed-order total variation regularizers

Pan Liu

A class of mixed-order \emph{PDE}-constraint regularizer for image processing problem is proposed, generalizing the standard first order total variation $(T V)$ . A semi-supervised (…

Adaptive image processing: first order PDE constraint regularizers and a bilevel training scheme

Elisa Davoli, Irene Fonseca, Pan Liu

A bilevel training scheme is used to introduce a novel class of regularizers, providing a unified approach to standard regularizers $T V$ , $T G V^{2}$ and $N s T G V^{2}$ . Optimal parameters…
