Automatic classification system of Raman spectra applied to pigments analysis
(2016-12-01)
Article
Open AccessRaman spectroscopy is one of the few non-destructive techniques capable of identifying pigments in art works. Raman spectra contain powerful information that can be used to identify unknown compounds and their chemical ... -

Automatic identification of artistic pigments by Raman spectroscopy using fuzzy logic and principal component analysis
(2006-10-27)
Article
Open AccessThis 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 ... -
Automatic morphology-based cubic p-spline fitting methodology for smoothing and baseline-removal of Raman spectra
(2017-01-01)
Article
Open AccessNoise filtering is considered a crucial step for the proper interpretation of Raman spectra. In this work, we present a new denoising procedure which enhances the Raman information whilst reducing unwanted contributions ... -

Identification of Raman spectra through a case-based reasoning system: application to artistic pigments
(2011-07)
Article
Restricted access - publisher's policyThis paper presents a methodology conceived as a support system to identify unknown materials by means of the automatic recognition of their Raman spectra. Initially, the design and implementation of the system were framed ... -

Morphology-based automated baseline removal for raman spectra of artistic pigments
(2010-06)
Article
Open AccessThe interpretation of a Raman spectrum is based on the identification of its characteristic molecular bands. However, the assignment of the vibrational modes is often compromised by the presence in the spectrum of an intense ... -
Practical identification of cobalt-based blue pigments detecting the induced photoluminescence by a He-Ne laser using a Raman spectrometer
(2024-02)
Article
Open AccessSince the early 19th century, the pigment historically known as cobalt blue has been one of the most widely used in artistic painting. Its many and excellent properties led to the rapid development of different synthesis ... -

(Universitat Politècnica de Catalunya, 2005-01-21)
Doctoral thesis
Open AccessLa investigación de los materiales constitutivos de obras de arte, en la que se encuadra esta tesis, es una de las aplicaciones de la espectroscopía Raman que ha ido creciendo en importancia en las últimas décadas. El ... -
Raman laser fiber optic strategy for non-destructive pigment analysis
(Office for official publications of the European communities, 2000)
Conference report
Restricted access - publisher's policyIn this work, the strategy, performances and applications of a Raman spectroscopy system with both optical fibre technology and two lasers (red and green) are presented. With this system, we have investigated certain yellow ...
