3D Reconstruction of Archaeological Pottery using Profile Primitives

The archivation process of ancient pottery is a very 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. In this work a bottom up design using a description language is the basis for the automatic classification and reconstruction. The description language holds all features of the fragment as primitives and all properties among features as relations. Classification of newly found fragments of unknown type is performed by comparing the description of the new fragment with the description of already classified fragments by computing the graph similarity. The subgraph with the highest similarity is then used to reconstruct the complete vessel out of the fragment.
