For most museums or art collections, art restoration has high costs and takes a lot of time. For restoration, paintings need to be shipped to special laboratories and the whole process could put a painting out of display/use for an extended period and be expensive ($10-15k for large paintings). Damages and restoration also lead to a decrease in the painting’s value. Furthermore, restored art pieces do not possess the same materials as the original piece, in some cases leading to faster deterioration than before.

HIFAM uses the HIP-MED technology providing a very high colour resolution that could detect the smallest changes in the painting. The technology is based on the analysis of the full-colour spectrum, from 400nm to 800 nm, for each pixel. The hyperspectral camera can take 40 points in the spectrum instead of only three (red, green and blue) that most of the current optical devices use, making the spectral information and the detection of characteristics not visible to the human eye available. By analyzing the full-colour spectrum, we make art monitoring an easy and not invasive process so that the most frequent deterioration problems can be prevented (e.g. cracking, flaking). Our technology can be used everywhere so that the art piece does not need to be moved and does not use invasive techniques like X-rays.
