  • The candidate will be hired by the CNRS, and the work will be lead in XLIM laboratory, more precisely located in Poitiers-Futuroscope. The research team is part of ASALI research axis (standing for "Image Synthesis and Analysis"). XLIM is a pluridisciplinary institute with several locations: Limoges, Brive, Poitiers and Angoulême. 440 researchers compose the laboratory, including CNRS researchers, professors, engineers, technicians, postdocs, PhD students, and administrative staff. Research are mainly developed in 3 main areas: (i) electronics, (ii) photonics, (iii) mathematics and computer science. 6 main axis compose the laboratory: Radio-Frequency Systems Radio-Frequency-ELITE Intelligent Systems & Networks Photonic Fibers and Coherent Optical Photon Sources Image Synthesis and Analysis Mathematics & Information Security and a reseach group in Bio-Health

    The proposed subject concerns interactive and realistic visualisation of cultural heritage artifacts. The funding corresponds to an ANR project called DIGITALIS, aiming at proposing digital tools for the management of archaeological research. This PhD research focuses on 3D interactive rendering of real objects from photographs. A 3D point cloud reconstruction is performed thanks to photogrammetry, and an existing visualization system manages on-the- fly photographs management as view-dependent textures. One first goal in this thesis concerns visual artifacts management such as flickering, or holes (due to the points rendering system). Another important issue concerns virtual relighting of the rendered objects since archaeologists aim at better understanding the original (potential) lighting contexts. Therefore, new models will have to be defined for understanding the object reflectance properties and new methods will have to be implemented for interactively managing new lighting environments. Finally, a part of the PhD research will be devoted to annotations management, since a part of the project consists in mixing 3D view with various types of information (text documents, photographs, manual illustrations, etc.). One fundamental question concerns the links and references between the reconstructed objects and referenced annotations.
