    OpenREC: A Framework for 3D Reconstruction of Models from Photographs
    (The Eurographics Association, 2017) Arroyo, Germán; Martín, Domingo; Tobias Schreck and Tim Weyrich and Robert Sablatnig and Benjamin Stular
    In this paper we introduce openREC to the scientific community, an extendable framework for reconstruction of 3D models from photographs. This system provides a framework designed for archaeologist, art restorers, architects, and other professionals, hiding not relevant details from the underlying complex commands that are only suitable for expert computer scientists. There is a huge amount of free and commercial tools for photogrammetry available, but none of them are really suitable for experts in other fields different from computer science. Free tools are not free of issues due to their huge complexity - most of them are commands based -, while commercial software are under strict close-source models that hide important details of their underlying algorithms, avoiding any tunning of their parameters. This article presents the core of openREC: a complex task manager that is able to chain different sub-tasks in a transparent way for the user, and that is able to deal with remote tasks through network without the need of any specific servers.

    Pairwise Matching of Stone Tools Based on Flake-Surface Contour Points and Normals
    (The Eurographics Association, 2017) Xi, Yang; Matsuyama, Katsutsugu; Konno, Kouichi; Tobias Schreck and Tim Weyrich and Robert Sablatnig and Benjamin Stular
    Stone tools constitute the main artifacts facilitating archaeological research of the Paleolithic era. The reassembly of stone tools is the most important research work for analyzing human activities of that period. In recent decades, large numbers of methods have been presented to solve various registration or matching problems for point clouds; however, few methods have been successfully applied to the matching of flakes, a type of stone tool. Therefore, we propose a new matching method for studying stone tools to improve archaeological research. Our method processes pairwise matching of stone tools based on contour points and mean normals of regions on all flake surfaces, according to the characteristics of the flake models. The sample experiments conducted in this study indicate that our new method achieves superior matching results for flakes, compared with the existing methods.
