Thèse - Visual attention modeling for 3D scenes in Virtual and Mixed Reality

Etablissement : Polytech'Nantes
Description du poste :


    The proposed PhD position concerns the item (3) above. Our goal is to build computational visual attention models that will predict both head and eye-movement in 3 and possibly 6 degrees of freedom environment, taking into account, mesh saliency, rendered scene saliency and human visual behavior (perceptual biases, bottom-up and top down influences, etc.). The visual attention models will also be used for predicting the interaction of the user in the virtual environment (translation + zoom / dezoom). The PhD candidate will benefit from the work already conducted in the LS2N IPI team related to 3D visual attention and perceptual biases:
