Here we show that a notion of congruence in statistical structureacross2 0frequency bandsproduces a useful definition of visualpatterns for perceiving target distinctness. In order to reach such a conclusion, ,firstly,the notion of congruence is used to induce a representational modelfor 2 0 images. Secondly, the visual-pattern based representational model is used to define a visual target distinctness metricthat involvesapplyinga simple decision rule over the distances between the visualpatterns. Finally, a relation is established between the computational distinctness metric and psychophysical target distinctness estimates.
