About me

Dr. Sophie Triantaphillidou is a Reader in Imaging Science, member of the Computer Science Department in the Faculty of Science and Technology. She is the Director of the newly formed Computational Vision and Imaging Technology research group, a cross-faculty group with members from the Faculties of Science and Technology and Media, Art and Design. She is also the designated course leader of the new MA/MSc Imaging Art and Science, MSc pathway. She specialises in imaging science, image quality and imaging system performance, colour imaging and human vision. She has been a staff member of the University of Westminster since 1996 and has contributed to the design and development and course leadership of undergraduate and postgraduate programmes relating to Imaging. Her research output was submitted in RAE2008 and REF2014 to the UoA11.

After graduating from the BSc in Photography and Electronic Imaging, she carried out PhD studies relating to the digitization of the historical W F. Talbot photographic collection, held by the Royal Photographic Society. In the early 2000's she worked with National Library of the Netherlands and the University of Westminster toward the evaluation of International Standards for image quality quantification for digitising library material and photographic collections and undertook post doctorate research in the quantification of the displayed image quality. The latter led to the development of a novel method for measuring sharpness in displays that has since become a benchmark.

In 2005, her research focus shifted to the influence that scene (image) content has in the visual perception of images and in image quality quantification. Since then, Sophie's research has mainly been concerned with the understanding of the interactions of the human visual system with the visual world, and still and video imagery.

Sophie was the Principal Investigator of the "Spatiotemporal visual contrast sensitivity to complex scenes" project,  funded by the MoD's DSTL. This 4-year project was concerned with the measurement and modelling of the human contrast sensitivity and discrimination to complex imagery. She is co-editor and contributor to the 10th edition of the Manual of Photography and a contributing author of the 7th and 8th editions of Langford's Advanced Photography. She has presented and published her research extensively. She is a member SPIE, IS&T, RPS and IEEE and sits in several committees and advisory boards relating to imaging.
