A reproducible digital morphometric framework for analyzing ceramic shape variation: a casestudy of Song-Yuan long-necked vases

This dataset supports the study "A reproducible digital morphometric framework for analyzing ceramic shape variation: a case study of Song-Yuan long-necked vases." It contains the raw and processed morphological data of 49 long-necked vases from the Song and Yuan dynasties, including line drawings, standardized contour coordinates, key morphometric parameters, and Principal Component Analysis (PCA) results. The data enable full replication of the contour extraction, parameterization, and statistical analyses presented in the paper.
