About the position

A three-year PhD position is available at the Department of Computer Science in Gjøvik.

The PhD position is focused on distinct but related fields of research within the field of Visual appearance measurement and understanding. The concept of visual appearance is currently far from fully understood, neither from the metrological nor perceptual point of view. Research ranging from fundamental aspects to high-impact applications in emerging fields such as 3D printing, material appearance and product design is thus needed in this topic. The PhD candidate in this position is expected to work towards Visual Appearance Capture and Modeling of Materials with Complex Reflectance Properties. 

The focus of the research will be to a) investigate and develop measurement method/setup for bidirectional reflectance measurement of materials with visual appearance attributes like gonio-chromatism, sparkle, texture, etc, b) model bidirectional reflectance and texture properties using physical and empirical reflectance models and optimization techniques, and c) identify and link visual appearance attributes to physically measurable quantities.

This PhD project is in line with the state-of-the-art research performed at the Norwegian Colour and Visual Computing Laboratory. 

The position reports to the Head of the Department.

Duties of the position

  • Conduct a stand-alone research project addressing the focus areas mentioned above.
  • Participate in the general activities of the Colourlab.
  • Participate in the general activities of the department.
  • Complete a training component as part of the PhD of a minimum of 30 ECTS.
  • Participate in international activities such as
    •  conference attendance,
    •  Contribute to technical committee meetings (like CIE, ISO),
    •  research stays at educational institutions abroad.
