Total Directional Variation for Video Denoising
Simone Parisotto, Carola-Bibiane Schönlieb
In this paper, we propose a variational approach for video denoising, based on a total directional variation (TDV) regulariser proposed in Parisotto et al. (2018), for image denois…
Higher-Order Total Directional Variation: Analysis
Simone Parisotto, Simon Masnou, Carola-Bibiane Schönlieb
We analyse a new notion of total anisotropic higher-order variation which, differently from the Total Generalized Variation by Bredies et al., quantifies for possibly non-symmetric…
Higher-Order Total Directional Variation: Imaging Applications
Simone Parisotto, Jan Lellmann, Simon Masnou +1
We introduce a class of higher-order anisotropic total variation regularisers, which are defined for possibly inhomogeneous, smooth elliptic anisotropies, that extends the Total Ge…
Anisotropic osmosis filtering for shadow removal in images
Simone Parisotto, Luca Calatroni, Marco Caliari +2
We present an anisotropic extension of the isotropic osmosis model that has been introduced by Weickert et al.~(Weickert, 2013) for visual computing applications, and we adapt it s…
Unveiling the invisible - mathematical methods for restoring and interpreting illuminated manuscripts
Luca Calatroni, Marie d'Autume, Rob Hocking +4
The last fifty years have seen an impressive development of mathematical methods for the analysis and processing of digital images, mostly in the context of photography, biomedical…
Digital Cultural Heritage imaging via osmosis filtering
Simone Parisotto, Luca Calatroni, Claudia Daffara
In Cultural Heritage (CH) imaging, data acquired within different spectral regions are often used to inspect surface and sub-surface features. Due to the experimental setup, these…
