Dr Ebi Osuobeni

Research group

Stephen is a member of our Anglia Vision Research.

Summary of research

Stephen's research area is in the psychophysical domain, and he is currently investigating stereoscopic depth discrimination in normal vision. His research follows on from the work already developed within Anglia Vision Research, which has focused on contour interaction and crowding. He is interested in developing this area in the stereoscopic domain, where he is determining characteristics of visual processes that are important to depth discrimination and how we can apply this knowledge to advance our understanding of visual impression in the spatial sense.
