a) Polynomial Texture Mapping (PTM) is a type of RTI imaging application, which was developed by Hewlett-Packard Imaging Labs and enhanced by the West Semitic Project at USC, addresses the difficulties in the photography of objects whose surfaces feature inscriptions or relief designs. They can be found on an array of archaeological objects and works of art such as inscriptions in stone or clay, plaques, coins, paintings, mosaics, relief sculpture, jewelry and other minor objects. It consists of a dome with a hole at the apex, and thirty-six Halogen lights embedded at randomly fixed intervals around the dome. An artifact is placed at the base of the dome, while a camera is positioned looking downward focusing, through the hole at the top, on the aforementioned object.
Cultural heritage research and practice is increasingly aided by, and dependent on, digital media. In the last decade, digital media technologies have begun to improve the documentation, management, understanding and communication of cultural heritage. The Cyprus Institute is spearheading, through its two centres CaSToRC and STARC, developments in digital imaging applications for national and regional research in Archaeology and Cultural Heritage. These efforts invest on the rich cultural landscape of the Eastern Mediterranean and the research initiatives of the European Union that have recognized the need for the development of digital libraries that will function as a user-friendly access points for cultural heritage.
