My research involves perceptual experiments on human observers. I also dabble in computational modelling of the underlying visual processes (to the limited extent of my mathematical ability).
My primary interests are in the perception of visual movement, and the perception of visual art. Research on motion covers a range of issues from low-level motion detection (eg in random dot patterns and gratings) to high-level interpretation of complex stimuli (eg biological motion). I am also interested in attempts to understand certain aspects of visual art in terms of the processing capacities of the human visual system.
My main criteria in selecting research problems are generally - (i) Is the perceptual effect theoretically interesting, intriguing and/or counter-intuitive (preferably all three)? (ii) Can I think of a worthwhile experiment? (iii) Can I persuade a computer to do it for me? An indication of the kind of things I have worked on can be gleaned from the collection of demonstrations in my motion perception tutorial, and the recent guide to implementing Adelson & Bergen's motion energy model.
