Summary on Grant Application Form |

Our perception of the world depends on the light reflected from the surfaces within it. Although the spectral content of this light changes when the spectrum of the illumination on a scene changes, we perceive the colours of surfaces to be largely constant. This phenomenon of colour constancy is important not only for what it tells us about how the visual system processes information in the world around us, but also because of its practical applications, for example, in the design of machine colour-recognition and colour-reproduction systems. The three main experimental techniques to be employed in this study are high-resolution multispectral imaging of natural scenes, eye-position recording outdoors and indoors, and psychophysical measurements in the laboratory. Data on surface-reflectance spectra and illuminants in natural rural and urban scenes, along with eye-movement data from those scenes, will be used to produce computer simulations in the laboratory matched to the resolution of the eye. Psychophysical measurements with those simulations, along with eye-movement controls, will allow us to elucidate the mechanisms underlying human surface-colour perception in natural scenes. In addition, we shall be able to determine minimum sets of spectral basis functions that can be used to generate visually acceptable reconstructions of those scenes.
