The Orion Pottery Repository – A Publicly Available 3D Objects’ Benchmark Database with Texture Information

Abstract

Performance evaluation is one of the main research topics in information retrieval. Evaluation metrics in combination with benchmark datasets (groundtruth) are used to quantify various performance aspects of a retrieval algorithm. In this paper, we present the Orion Pottery Repository, a publicly available and domain specific benchmark database. It is based on open source technologies and contains a total of 160 textured 3D digital replicas of ancient Greek pottery. The dataset offered through the repository can be used for performance evaluation experiments of 3D data retrieval algorithms. Orion’s content has been classified according to a pottery shape categorization defined by an in-house developed thesaurus. The repository provides mechanisms that allow a wide range of metadata handling that are based on the CARARE metadata schema which among others it offers the ability to include information related to digitization procedures and their properties.
