Research

We develop mathematical and computational methods to assist in archaeological research.

The subjects which interested us most in the past years are:


Symmetry and roughness of lower paleolithic handaxes

Typology and classification of ceramic artifacts based on the curvature functions of their profiles.

The asymmetry of two handaxes, defined in terms of their curvature function

The steps leading from the original drawing of a vessel to its curvature function

Measurements of deviations from perfect cylindrical symmetry of wheel produced pottery

Optimal choice of prototypes in a given assemblage using cluster analysis

A non uniform plate from Tel Dor and six profiles measured at different sections using the profilograph

A cluster tree of  storage jars from Hazor and Tyre defined in terms of shape information only. The colors indicate the provenance

Measurements of deformations of horizontal sections of ceramic vessels

Accurate alignment of 3D reconstructions of pottery fragments

A cluster tree of storage jars from Hazor and Tyre defined in terms of shape information only. The colors indicate the provenance.

From a scanned image to a standard profile drawing. a. The image obtained from the scanning camera. b. Computed symmetry axis for best position, and three intersecting planes. c. The 3 profiles - their perfect overlap proves the successful determination of the symmetry axis. d. Computerized conversion of the profile to a standard drawing. The carination marks/lines were computed from the curvature function.
