Reusing 3D Measurement Data of Lithic Artifacts to Develop Analytical Methods

Abstract

This article focuses on how we reused a 3D data publication of lithic artifacts from the Upper Palaeolithic site of Grotta di Fumane and how it influenced our work creating workflows and new software solutions. These models are annotated recreating already published drawings and enriched by the scar position in an operational sequence. The annotated 3D models are then used as base dataset for developing new software solutions. The first is an automatic segmentation using Morse Theory, in which their performance was tested against the dataset. And in the second, it was used to build graph models and create a parameter-based predict algorithm to automatically predict the relation between adjacent scars.
