“…A survey of the archaeological literature shows that the concept of applying computers to generate ceramic classifications and store large datasets of ceramic information in databases is not new (Bishop et al 2005;Durham et al 1995;Hall and Laflin 1984;Kampel and Sablatnig 2003;Lengyel 1975;Lewis and K. J. Goodson 1991;Liu et al 2005;Main 1978;Sablatnig and Menard 1997;Schurmans et al 2001). However, these attempts have primarily focused on small datasets; simple methods of ceramic classification and have not progressed beyond their initial demonstration phases.…”

There is an increasing demand within the humanities and social sciences to use computers to analyze material culture and discover patterns of historical and anthropological significance. Using southern Levantine Iron Age (ca. 1200-500 BCE) ceramics as a test case, the Pottery Informatics Query Database (PIQD) provides a novel solution for constructing regional ceramic typologies. Beyond digitally archiving 2D/3D-scanned ceramics, the PIQD encodes ceramic profiles as mathematical representations. This method of digital preservation enables rapid queries to be conducted in a mathematically grounded approach. In this sense, the queries are similar to online Basic Local Alignment Search Tool searches developed in the field of genetics by rapidly associating large quantities of digital vessel profiles to each other based on similar morphological traits. The PIQD is an open-source online tool that enables scholars and students to test humanities-related hypotheses against ceramic data in ways that conventional publications or other databases cannot provide. Regional spatial patterning of the ceramic data is delivered over a Google Earth-based user interface. In this paper, we present the PIQD as an objective method for developing a comprehensive ceramic typology of an entire region of archaeological study and provide an arena to conduct novel scientific research. We then demonstrate through a case study its analytical capabilities to handle large datasets of 3D scans and digitized 2D ceramic profiles and generate cultural inferences with the ceramic assemblages of the Iron Age II "Edomite" region located in modern southern Jordan. PIQD adds an important methodological tool to the post-excavation cyber-archaeology tool box.

“…The minimum fragment size can be determined by estimation of the gaussian curvature κ min in respect to noise and resolution of the 3D-scanner [9]. As ceramics are not perfectly symmetric, the minimum size required for proper orientation depends on the technique used for manufacturing.…”

Motivated by the requirements of modern archaeologists, we are developing a documentation system based on structured light for acquisition of ceramics. Fragments of ceramics are daily finds at excavations and important for archaeological research, because their shape leads to information about ancient cultures. The shapes used for documentation are called profile lines and estimated by a vertical cross-section of orientated fragments. As ceramics have been produced using rotational plates for several thousands of years, the rotational axis can be used for orientation. Therefore we conducted experiments using existing methods for estimation of the rotational axis. The drawbacks of these methods are the requirement of either complete objects or industrialized quality of symmetry. Therefore we show a new method using circle templates, which has been inspired by the manual method of archaeologists. In this work we present results using previous and related work in comparison with the estimation of the rotational axis using circle templates. The results of the presented methods are shown for synthetic data, well-known fragments and real data acquired at an archaeological excavation. Finally a conclusion and an outlook is given.

“…Hall and Laflin (1984) used B-spline methods to convert digitized pottery containers silhouettes into one or more mathematical curves (see also Smith 1985;Kampel and Sablatnig 2003b;Mom 2005Mom , 2006Nautiyal et al 2006). Polynomial interpolation has a long history in archaeology, especially in the case of pottery studies.…”

ForewordThe aim of this new edited volume is to present the various aspects of morphometrics in a way that is accessible to readers who might not be acquainted with the voluminous literature on this topic. Morphometrics is the quantitative study of organismic form. It attempts to quantify, precisely and as completely as practical, the information on size and shape that often is readily apparent to the investigator yet difficult to adequately characterize in numerical terms. Morphometric studies thus provide an initial step in the understanding of patterns of variation among individuals and groups of organisms, and typically form an important groundwork for analyses of structure, function, and evolution. As such, morphometrics has become central to the biological sciences.The field of morphometrics has transitioned relatively smoothly through several different phases, from D'Arcy Thompson's (1917) extraordinary and influential treatise on growth and form, through the influx of algebraic and statistical methods related to eigenanalysis, cluster analysis, and multidimensional scaling, to direct landmark-based methods that echo Thompson's original intents and insights. The history of these ideas is reviewed by Richard Reyment, who has himself been an important contributor to and synthesizer of morphometric theory and practice.Included among the other chapters are examples of applications of morphometric methods in palaeontology and neontology, fishery science, archaeology, and evolutionary ecology. The volume also includes reviews and perspectives on a number of currently important methodological topics in morphometrics, including approaches to the analysis of morphological variation and clinal variation, the quantification of curvature, discrimination and classification, automated typology, use of morphometric data in evolutionary and phylogenetic analysis, and the integration of traditional distance-based methods with geometric morphometrics.The geometric morphometric methods that have been developed over the past several decades to extend beyond the limitations of traditional distance-based methods have become transformed into the new standard research protocol. As the technologies of measurement, analysis and display continue to improve; our current methods will continue to evolve. For those who are entering the field, it is hoped that v vi Foreword the papers in this volume may serve as a current set of landmarks in time, reflecting over past work and pointing toward the future.
