* Abstract (approx. 100 words)
In the archaeological application of stone tools, the scale drawing, which is hand-drawn from measured stone tools, is traditionally used.In the scale drawing creation, a base drawing which consists outline and ridge lines is initially drawn from geometric features of shape. If the base drawing is automatically extracted, the working hours are reduced. To overcome this issue, this paper proposes a feature line extraction method using the Mahalanobis distance metric. To verify our method, the extracted feature lines are compared to the ground truth of base drawing drawn by archaeological illustrators. We confirm the effectiveness of our method.
