Ornamental Stone Quality Control by Imaging Based Spectroscopy

Ornamental stone products are commercially classified on the market according to several factors related both to intrinsic lythologic characteristics and to their pictorial attributes. Such attributes are influenced by working actions performed to realize the final product. This latter aspect is quite critical because stone surface finishing can contribute to enhance certain aesthetic features of the stone itself. The study was addressed to develop an innovative set of imaging based procedures able to quantify the aesthetic quality of travertine marble products taking into account both physical and aesthetical stone characteristics. Results showed as, adopting the developed procedures, a correct quality labelling of the travertine marble finished products can be achieved in an automatic way
