Documentation of coins via Reflectance Transformation Imaging (RTI)

Abstract

<jats:title>Abstract</jats:title> <jats:p>The Reflectance Transformation Imaging (RTI) recently represents widely used method for documentation of archaeological artifacts and research in this field. The RTI creates digital presentation of images from sequence of snaps with lighting from different directions. Information about lighting from this group of images is mathematically synthesized in a RTI image which can help the user to illuminate interactively the object surface and improve the final image in significant details. The RTI method is very successful in improving details of badly preserved coins, sometimes illegible for the first sight.</jats:p>
