New insight about the mural painting branches of Roman baths in Reggio Calabria
2023
The Roman baths in Reggio Calabria (Italy) provides many information regarding both engineering and technology for this type of buildings. A small treasure of three survived mural paintings enclose information about the artistic style and the ancient luxury of the baths. In order to get light on the executive technique and conservation state we performed the investigation of these paintings by following a non invasive approach composed of multispectral imaging and spectroscopic analysis. By so doing we determined the pigment palette and the distribution of some pigments allowing us to make some hypothesis about the executive technique and provide a basis for a future virtual restoration of …
Multispectral analysis of color vision deficiency tests
2011
Color deficiency tests are usually produced by means of polygraphy technologies and help to diagnose the type and severity of the color deficiencies. Due to different factors, as lighting conditions or age of the test, standard characteristics of these tests fail, thus not allowing diagnosing unambiguously the degree of different color deficiency. Multispectral camera was used to acquire the spectral images of the Ishihara and Rabkin pseudoisochromatic plates in the visible spectrum. Spectral data was converted to cone signals, and successive mathematics applied to provide a simple simulation of the test performance. Colorimetric data of the each pixel of the test image can be calculated an…
