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.本数据集为研究论文《可复现数字形态计量框架用于陶瓷器形变异分析——以宋元长颈瓶为例》提供支撑。其包含49件宋元时期长颈瓶的原始及经处理的形态学数据，涵盖线描图、标准化轮廓坐标、关键形态计量参数，以及主成分分析（Principal Component Analysis，PCA）结果。该数据集可完整复现论文中所述的轮廓提取、参数化及统计分析流程。
