Summary on Grant Application Form |
|
wall in a room illuminated by light from a window will display a colour and luminance gradient due to the non-uniform illumination and yet we are able identify the colour of the wall as being the same along its surface. This ability is one of the most striking examples of human colour constancy -the pacity we have for recognising a surface as being the same colour regardless of illumination conditions and context. Classical studies using simple iform colour patches simulated on a CRT display do not predict this ability. In this project we will use visual psychophysics techniques, that is nonsive study of observers responses to controlled visual stimuli, to study the perception of colour and luminance gradients by our visual system. In a vel approach we will use as stimuli both computer generated images presented on a screen, and objects and lights in a real world set-up. This study I help us determine the role played by non-uniform conditions of lighting and reflectance in colour constancy; our findings will have implications for h basic vision science and computer graphics applications. It will further our understanding of top-down visual processing in the human brain -i.e.knowledge of a scene can be derived from previous experience or assumptions combined with sensory stimulation- and will influence the design realistic computer simulated environments.
