Shape analysis of pottery using elliptic fourier descriptor and 3D scanning

Abstract

A method based on elliptic Fourier descriptor (EFD) is used for the classification of pottery ware. Traditionally, the contour lines used in elliptic Fourier descriptor is measured in 2D image. In this article, we took the pottery from Tianma-Qucun Burial site as an example, introduced a new method for obtaining data using three-dimensional scanning technology and computer programming. Compared with the traditional extraction method, this method can improve measurement speed and accuracy. The extracted data are used to classify the pottery ware by elliptic Fourier descriptor, which is different from the methods used in traditional archaeology. It provides a new tool to illustrate the relationship between objects.
