The visual system develops from birth through an interaction of genetic predisposition and environmental exposure.  As adults, some of the ‘software’ of vision maybe tuned based on learning - for instance the visual skills developed by air traffic controllers - but the underlying architecture, the visual system’s basic components, for instance, the detectors for certain visual features (spatial frequency components, edges, motion, orientation) are typically thought to comprise a fixed set.  In this ongoing research, we question this assumption by trying to build new feature detectors.
