Towards the Development of a Model of Vision: An Investigation into the Architectures and Mechanisms of Visual Perception

Abstract

A conceptual model of visual perception has been developed using a multidisciplinary approach which combines both top-down and bottom-up descriptions of vision. Top-down psychological theories of visual perception have been investigated resulting in the development of a theory of perception which combines the best of existing accounts. Perception is defined in terms of a combination of "data driven" and "concept driven" explanations. Bottom-up neurophysiological descriptions have also been investigated to provide possible descriptions of structure and function for the development of a conceptual model based upon the theory. An attempt is made to provide a "complete" account of visual perception through the development of both the theory and conceptual model. Further it is envisaged that the development of such a model will provide new insight into the development of artificial vision systems and new algorithms for perceptual function in such systems.
