PhD position Univ. Nantes: QoE evaluation and prediction in light-field and volumetric imaging

Context: The PhD fellowship is funded by the European Training Network Realvision, a Marie Sklodowska Curie action of the European Commision which aims at training a new generation of scientists, technologists, and entrepreneurs that will move Europe into a leading role in innovative hyper-realistic imaging technologies.The position is available at University of Nantes (LS2N/IPI), under the supervision of Pr Patrick Le Callet and the co-supervision of Ass. Prof. Toinon Vigier.

Topic: True hyper-realistic imaging is intended to provide the quality and accuracy of visual content that matches the capabilities of human visual system. To achieve this goal, visual content needs to be represented in multi-dimensional space, going beyond the traditional 2D + colour + time representation. Such new visual dimensions required for hyper realism include light field for motion parallax (free-view-point), binocular stereo, and focus cues; spatial and temporal resolution for sampling close to the limits of the eye; and colour and high dynamic range for accurate reproduction of all colours and light levels experienced in the real-world. All these perceptual aspects need to be considered at all technological stages of the hyper-realistic image delivery chain, from capture to the perception and quality evaluation. In this context, the goal of this PhD thesis is to develop new cognitive model, tools and measures to assess quality of experience (QoE) in light-field and volumetric imaging. It includes the design of ad hoc experimental methodologies (direct and indirect approach) to characterize observer’s experience and related analysis tools.

Required qualifications: Master’s degree in Computer Science or Image/Signal Processing or Cognitive Sciences. Interest in new imaging technologies, human perception and experimental science.

Starting date: No specific constraint, around September 2018.
