Ultra-rapid categorization requires visual attention: Scenes with multiple foreground objects.

abstract：:The statistical arrangement of oriented segments in natural scenes was recently proposed to be indicative of a cocircularity rule. In particular, the probability density function of the relative position of two oriented segments was found to be maximal along fixed angles on the plane, consistent with the two segments ...
