Two researchers from Universidad Politécnica de Madrid (UPM) inward collaboration amongst a researcher from Czech University of Life Sciences Prague (CULS) cause got developed a methodology to respect archaeological elements invisible to the naked eye.

[Credit: Aroa Gutiérrez Alonso] Starting from photographs taken amongst mutual digital cameras as well as the attain of the visible spectrum, a squad of researchers from School of Land Surveying, Geodesy as well as Mapping Engineering at UPM as well as Faculty of Environmental Sciences from CULS propose a novel non-invasive methodology of archaeological documentation as well as analysis to demo digital elements that are invisible to the naked eye. The method consists of applying techniques of both remote sensing as well as spectral handling inward corporation to uncover hidden elements as well as after acquit out their morphometric analysis.
Mercedes Farjas, Aroa Gutiérrez as well as José Antonio Domínguez started past times studying a limestone mold inward the lab. The get-go destination was to assess the influence of the angle of the low-cal of the photographs.
Later, after studying the number of various filters on the mold, the researchers carried out combination tests of the filters inward corporation to practise a protocol of sequential application that allowed them to obtain conclusive results. As a resultant of these tests, they selected a gear upwardly of filters as well as established an corporation of application.
Mercedes Farjas says, "The digital handling protocol starts amongst unlike taken photographs. After a choice of the optimal pictures, nosotros apply a convolution filter as well as morphology, a texture filter as well as a standardized index of prints that allows us to spend upwardly facial expression inside the image."
Additionally, inward corporation to report the existing pigments on the engraving, researchers applied additional techniques of detection such every bit the supervised classification as well as 3-D rendering algorithms to assess the surface from a unmarried photograph.
After numerous lab trials, the verification as well as validation of the consummate methodology of the processing were carried out inward various caves of a high archaeological value from the Tamanart Valley inward Kingdom of Morocco as well as the Casares Cave inward Guadalajara, Spain.
The results demo the viability of the proposal to respect hidden information inward engravings as well as to supply researchers amongst digital supports to acquit out a detailed report of the geometries. Aroa Gutiérrez says, "We specially recommend this methodology for studies nearly the deterioration of national heritage since this methodology tin supply information on erosion the stone as well as acquit out relevant qualitative as well as quantitative analysis."
The deterioration of the back upwardly fabric does non permit a unique reading as well as interpretation of the texts as well as to define the content is of peachy importance for the historical reconstruction of the facts.
The report is published inward Archaeological as well as Anthropological Sciences.
