(A) An image is taken (1) and is split into 12 orientation-filtered images (2), which are sent to their own layers in the corresponding group where Each of the 12 preferred orientations are rotated at 15 degrees (3). After interaction the output is collected at a top-level saliency map (4). (B) Interaction between layers is governed by collinearity. More collinear elements excite each other (a and b angles are small) while less collinear elements suppress each other (Alpha and Beta are large). (C) Elements like (1) enhance, elements like (2) suppress, and highly parallel elements can enhance, like in (3).
