Pattern Recognition Based on Principal Component Analysis in Raman Spectroscopy Applied to Artistic Pigments
It is proposed an algorithm, based on the general scheme of pattern recognition and on the technique of principal components analysis, developed to automatically select the reference Raman spectrum corresponding to an unknown Raman spectrum, which is a ‘fingerprint’ of the analyzed material. It is applied to the identification of artistic pigments in art works. The performance of the implemente...
متن کاملAutomatic Identification of Artistic Pigments by Raman Spectroscopy Using Fuzzy Logic and Principal Component Analysis
This work offers an automatic identification system of Raman spectra of artistic pigments. The proposed methodology is based on a fuzzy logic system, and uses principal component analysis to reduce redundancies in data and the correlation operator as an index of similarity between two Raman spectra. Moreover, as sometimes pigments are used in mixtures by artist, the designed system is able to r...
متن کاملRaman spectroscopy for the investigation of carbon-based black pigments
Raman spectroscopic studies of carbonaceous materials are, until now, mainly devoted to geological and industrial materials. On the other hand, it is known from artistic literature that many varieties of carbon-based black pigments were produced and used in different places and times, and according to the artist’s preferences. The ability of Raman spectroscopy to analyse particles down to 1μm a...
متن کامل10 Years of Surface-Enhanced Raman Spectroscopy in Art and Archaeology
The identification of organic colorants in works of art has traditionally been one of the most difficult challenges in cultural heritage science. While non-invasive methods such as X-Ray fluorescence spectrometry (XRF), or Raman microscopy are extremely useful for the identification of inorganic pigments, they remain generally unsuitable for the analysis of most organic colorants. The absence o...
متن کاملAn innovative surface-enhanced Raman spectroscopy (SERS) method for the identification of six historical red lakes and dyestuffs
Surface-enhanced Raman spectroscopy (SERS) was used in this work to obtain highly detailed spectra of artists’ red lake pigments and colorants. In the past, Raman spectroscopy has been successfully employed to identify many pigments and modern synthetic dyes. Unfortunately, red lake pigments and dyes commonly employed in artistic production from antiquity to the mid-nineteenth century are often...
