A lower bound on the number of mechanisms for discriminating fourth and higher order spatial correlations

Seamons, John W; Barbosa, Marconi; Bubna-Litic, Anton; Maddess, Ted


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 [3]. Isotrigon textures can be used to probe the sensitivity of the human...[Show more]
