Hyperspectral and Polarization images of an experimental oil painting

This repository contains 4 hyperspectral images in the VNIR range (400 - 1000 nm) and 4 hyperspectral images in the SWIR range (1000 - 2500 nm) of an experimental oil painting. Each scene (P0,P1,P2,P3) is associated with the capturing with a linear polarization filter placed in front of the hyperspectral cameras. The rotation angles of the polarizers are found in the spreadsheet 'theta.xlsx' Please cite as: Grillini, Federico, et al.
