Ruili received her Bachelor and Master degrees specializing in Printing Engineering and Image Science and Engineering respectively from Beijing Institute of Graphic Communication, China. Her research interests include color image reproduction, color appearance modelling, color vision and perception.

Aspirations within projects:

She is ready to work hard and make contributions for this project and looking forward to cooperating with others for the same goal. Hopefully, the research project could be finished successfully and applied to the industries. Moreover, she is eager to obtain more professional knowledge and enhance my research skills about the color 3D printing to make me become an expert in this field.

ESR7: Accurate colour reproduction of human face using 3D printing technology

Main Supervisor:



  • Collect a skin colour database including spectral reflectance and 2D & 3D colour images of human faces,
  • Establish a 3D colour image reproduction workflow for faithfully reproducing skin tones of human faces,
  • Reproduce accurate high-fidelity skin colours using 3D printing,
  • Develop a perceptual skin appearance metric predicting the similarity between natural and manufactured skin under natural lighting conditions.
