Microcomputed tomography is a valuable tool for studying ancient ceramics technology. Analysing pottery 3-D images is a challenging issue, the data being extremely noisy and heterogeneous. Quantitative criteria are introduced for the characterisation of a previously unrecognised pottery building method, the Spiralled Patchwork Technology (SPT). An analytical protocol has been implemented that applies to 3-D reconstructions of ceramic sherds and integrates automatic segmentation of porous systems and shape recognition using Hough transform. It enables discriminating between SPT and other techniques for vessels manufacture, and opens up many perspectives for independent characterisation of ancient technical gestures in ceramic technology.

用于区分古陶器不同成型技术的微计算机断层扫描：新的分割方法和孔隙分布识别

微型计算机断层扫描是研究古代陶瓷技术的宝贵工具。分析陶器 3-D 图像是一个具有挑战性的问题，数据非常嘈杂且异质。引入了定量标准来表征以前未被认可的陶器制造方法，即螺旋拼凑技术 (SPT)。已经实施了一种分析协议，该协议适用于陶瓷片的 3-D 重建，并集成了多孔系统的自动分割和使用 Hough 变换的形状识别。它可以区分 SPT 和其他船舶制造技术，并为陶瓷技术中古代技术姿态的独立表征开辟了许多视角。
