A Virtual Restoration System for Broken Pottery
Aiming to assist the archaeologist to restore excavated sherds, a virtual restoration system for pottery shape relics is developed based on their two characteristic features: symmetry axis and profile. An effective method of estimating the axis of the surface of revolution is presented first; then an approach for computing the complete profile is proposed. Because some pottery contains holes or...
متن کاملPottery Sample Descriptions
Each pottery specimen analyzed was selected on the basis of its potential to reveal information about taxonomic relationships, in addition to providing samples for chemical and mineral analyses. Preference was given to larger sherds with distinct temper and surface treatment characteristics. Table A.1 describes the provenience of the 70 samples. Table A.2 includes the paste and temper character...
متن کاملOn Estimating the Position of Fragments on Rotational Symmetric Pottery
The archivation of ancient vessel-fragments is a time consuming but important task for archaeologists. The basis for classification and reconstruction is the profile which is the cross-section of the fragment in the direction of the rotational axis of symmetry. Hence the position of a fragment (orientation) on a vessel is important. In this work the estimation of the axis of rotation out of ran...
متن کاملAutomated Documentation System for Pottery
Motivated by the requirements of the present archaeology, we are developing an automated documentation system for archaeological classification and reconstruction of ceramics. Our system works with the profile of an archaeological fragment, which is the cross-section of the fragment in the direction of the rotational axis of symmetry. Ceramic fragments are recorded automatically by a 3D-measure...
متن کاملInvestigation of roman age pigments found on pottery fragments
This work deals with the study of the physico-chemical characteristics of pigments found on pottery fragments from an excavation in Vicenza (Contrà Pedemuro S. Biagio). The examined pigments were: a blue colour on a terracotta fragment; an olive green on a black pot bottom; yellow traces on a red depurated terracotta; an olive green plate bottom with an amaranth “a fresco” test; a deep red on a...
