PhD Position LS2N / Univ. Nantes: QoE evaluation and prediction in light-field and volumetric imaging

QoE evaluation and prediction in light-field and volumetric imaging



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.



You are passionate about new imaging technologies. You have interest in human perception and experimental science. You have a master degree in signal/image Processing or computer science or cognitive sciences. If you are an enthusiastic and talented student or young professional thinking of doing a doctorate, you could be a good candidate.



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.

Application procedure

Researchers can be of any nationality. They are required to undertake transnational mobility (i.e. move from one country to another) when taking up their appointment. Nationality is therefore not a criterion. Rather the location of the researcher’s residence or main activity during the 3 years prior to their recruitment is the determining factor.

Candidate apply electronically  and should provide:

  • a cover letter, where the applicant present her / his profile and provides a motivation for application
  • a detailed Curricula Vitae (CV),
  • Master’s degree transcripts that are validated
  • any additional documents that proof the eligibility for the corresponding doctorate degree program and proof of sufficient English language skills
  • letters of recommendation

Applications must be sent to

Deadline for application: 09-30-2018
