Fig. 14

This figure presents a failure case in the object shape classification of improved YOLOv11, where the ceramic vessel with a damaged spout was incorrectly classified as a “Pot” instead of its correct category (e.g., “Bottle'') due to disrupted neck-body continuity. This figure is based on original fieldwork photographs taken by the author, its feature bounding boxes and classification annotations produced using the author’s improved YOLOv11 model.
