    A Mesh Correspondence Approach for Efficient Animation Transfer
    (The Eurographics Association, 2019) Moutafidou, Anastasia; Fudos, Ioannis; Vidal, Franck P. and Tam, Gary K. L. and Roberts, Jonathan C.
    Animating a novel character not only needs a lot of effort and time but also requires the intervention of an experienced user. Moreover, the traditional animation pipeline for a set of characters can be a tedious and cumbersome process which often needs to be repeated several times to correct artifacts. We propose a user-friendly, semi-automated efficient method which is realized in two phases: (i) mesh correspondence, and (ii) skeleton and skinning transfer. We have developed a software tool for realizing the entire process without the need of third party software. We have improved the efficiency of the entire animation transfer process. To substantiate this, we provide a comparative performance evaluation with previous competent approaches.

    Multiple Material Layer Visualization for Cultural Heritage Artifacts
    (The Eurographics Association, 2018) Moutafidou, Anastasia; Adamopoulos, Georgios; Drosou, Anastasios; Tzovaras, Dimitrios; Fudos, Ioannis; Sablatnig, Robert and Wimmer, Michael
    Material aging has a significant effect on the appearance of cultural heritage objects. These aging effects depend on material composition, object usage and weathering conditions but also on physical and chemical substance parameters. Some types of changes in the materials underneath the visible layers can also be detected and subsequently simulated. Furthermore, recent 3D printing technology enables exporting 3D objects with transparency information. We report on the development of software tools for visualization of material aging for artwork objects that can be used by curators and archaeologists to understand the nature of aging and prevent it with minimal preservation work.
