Graeme Phillipson

PhD student 2006 – 2012

Graeme was a student from the Neuroinformatics Doctoral Training Centre at Edinburgh University. He did both his MSc project (with distinction) and his PhD in my lab. He studied how vertical disparity affects both the solution of the correspondence problem, and how this is subsequently used in perception. For his MSc project, he looked at illusions related to the induced effect, in which vertical magnification varied across the visual scene. His work suggested that vertical disparity is measured on a much finer scale than previously thought. For his PhD work, he examined how the brain handles changes in binocular geometry which arise as you view objects at different distances, discovering that stereo correspondence is optimised for long viewing distances and that, in consequence, performance on a stereo task can actually be improved by adding in vertical disparity. After leaving my lab, he worked with Bas Rokers at Madison, Wisconsin. His website is web.me.com/graeme.phillipson.

Fredrik Allenmark

PhD student 2008 – 2011

Fredrik has an M.Sc. in Engineering Physics from Chalmers University of Technology, Gothenburg, Sweden. For his PhD, he studied how well correlation-based models of human stereo correspondence account for human depth perception, looking in particular at the detection of sine-wave and square-wave disparity gratings. He demonstrated that the current models of this process could not account for our perception of square-wave disparity gratings, and produced a new version which fixed this problem. He is now doing a one-year postdoc with me.
