A lower bound on the number of mechanisms for discriminating fourth and higher order spatial correlations
The human visual system must employ mechanisms to minimize informational redundancy whilst maximizing dynamic range and maintaining that which is behaviorally relevant [1, 2]. Previous research has concentrated on two-point correlation properties, as captured by spatial frequency and orientation tuning. There has been less research into higher-order correlations although they may inform us about cortical functioning . Isotrigon textures can be used to probe the sensitivity of the human...[Show more]
