Are you aware of the impressive performance of human vision in sensing local position, orientation & relative sharpness of lines & edges in images - also the extreme sensitivity of human vision to local movement or differential stereo depth of lines & edges?

Do you ever wonder how human vision is so very sensitive to subtle shades of colour?

Were you aware of the fact that the retinal image formed at the back of the eye, even for good (20/20) vision is still grossly blurred as compared to accepted optical imaging rules: also that it is totally uncorrected for chromatic aberration? Yet what we perceive is both sharp & without colour fringing!

Have you ever wondered how the images from our two eyes of parts of the scene on which we concentrate are instantly & automatically fused?

Are you interested in the properties of human peripheral vision and visual search?

Would you like to know more about any of these matters - and possibly to be able to simulate these things (and much more) objectively on your computer? If so, read on - or click here for simple demonstrations of some of the properties.
