The authors describe the use of digital image processing techniques aimed at achieving a criteria for quantitative comparison. Usually, these procedures are executed using visual superimposition of images and constrained by the lack of rescaling and anamorphic making up that could be used to cancel the optical distortions caused by lenses. The criteria used within the experimental activity are aimed at helping the archaeologists without changing their traditional research methods. These techniques can be seen as an interesting tool able not only to aid impartial decision making but also to enhance the autoptic analysis of the findings. The most important algorithms pertaining to image processing have been used for investigating the origin and the age of moulded and handmade objects.

In ancient Roman world the monumental stone inscriptions had always an harmonic proportion. The metric measurement cannot define the train of their preparation; but the careful lay-out standard surely obeyed - perhaps also spontaneously - to some exact rules of the proportion (e.g. Hambidge's "dynamic symmetry", valid in some artistic fields) aimed at the primary purpose of all epigraphical expressions: the most efficacious communication. Some examples, mathematically verified by CILEA, are sown here.
