Mathematical osmosis imaging for multi-modal and multi-spectral applications in Cultural Heritage conservation
Simone Parisotto, Luca Calatroni, Claudia Daffara
In this work we present a dual-mode mid-infrared workflow [6], for detecting sub-superficial mural damages in frescoes artworks. Due to the large nature of frescoes, multiple therm…
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…
Efficient Osmosis Filtering of Thermal-Quasi Reflectography Images for Cultural Heritage
Simone Parisotto, Luca Calatroni, Claudia Daffara
In Cultural Heritage, non-invasive infrared imaging techniques are used to analyse portions of deep structures behind wall paintings. When mosaicked, these images usually suffer fr…
Alternating Direction Implicit (ADI) schemes for a PDE-based image osmosis model
Luca Calatroni, Claudio Estatico, Nicola Garibaldi +1
We consider \emph{Alternating Direction Implicit} (ADI) splitting schemes to compute efficiently the numerical solution of the PDE osmosis model considered by Weickert et al. for s…
