The Perception of Brightness and Colour: Neurophysiology, Psychophysics and Computation.

Abstract

Progress in research in 3 areas of computational visual neuroscience is summarized. The first project has assessed the receptive field organization of neurons in the primate striate cortex. A new model is proposed for cortical receptive fields based on linear combinations of difference of Gaussian functions. The second project is directed towards measuring the chromatic properties of cortical cell receptive fields. The third project is assessing current computational models of the perception of three dimensional surfaces using psychophysical techniques with human observers. Keywords: Visual perception, Neurophysiology, Image processing, Information processing, Visual cortex.
