“…VNIR spectral imaging has also found innovative applications for the in situ study of mural paintings and rock art [53,54,93]. Despite the constraints imposed by outdoor measurements on large-scale paintings and inscriptions, spectral differences in pigments with similar coloration but different chemical composition were recorded in the Mayan hieroglyphs found at the Naj Tunich cave in Guatemala [53,54].…”

“…Despite the constraints imposed by outdoor measurements on large-scale paintings and inscriptions, spectral differences in pigments with similar coloration but different chemical composition were recorded in the Mayan hieroglyphs found at the Naj Tunich cave in Guatemala [53,54]. The data obtained were further analysed by clustering analysis, which led to differentiation between original pigments and later repainting, and revealed interrelationships between the inscriptions.…”

Spectral imaging technology, which records simultaneously spectral and spatial information about an object, was initially developed for remote sensing and has since been successfully applied to other areas of research. Although relatively new to the field of conservation, this non-invasive method of investigation has already provided promising results in the analysis of paintings and written documents, the characterization of materials and digital documentation. This article reviews the published literature relating to the application of multispectral and hyperspectral imaging for the study and conservation of works of art and presents some new perspectives offered by this innovative and fast-developing technology.

“…One of the first applications of multispectral imaging was reported in [6]. Furthermore, Ware et al [7] performed the characterization of pigments with similar coloration and different chemical composition in Maya murals found at the Naj Tunich cave in Guatemala; a clustering analysis of the data led to differentiation between the original and later paintings.

This paper introduces a lattice algebra procedure that can be used for the multispectral analysis of historical documents and artworks. Assuming the presence of linearly mixed spectral pixels captured in a multispectral scene, the proposed method computes the scaled min- and max-lattice associative memories to determine the purest pixels that best represent the spectra of single pigments. The estimation of fractional proportions of pure spectra at each image pixel is used to build pigment abundance maps that can be used for subsequent restoration of damaged parts. Application examples include multispectral images acquired from the Archimedes Palimpsest and a Mexican pre-Hispanic codex.

“…Bandpass-based spectroscopy contains a set of narrowbandpass filters on a motorized wheel or a liquid crystal tunable filter [Ware et al 2000;Sugiura et al 2000;Attas et al 2003;Rapantzikos and Balas 2005]. A monochromatic solid-state detector in the systems measures the filtered narrow-band spectra, where the spectral and spatial resolutions depend on the specifications of the filters and the sensor.…”
