Model of human pattern perception: association fields for adaptive spatial filters

The architecture of an association field is proposed to permit linking and segmentation of filter-elements across spatial frequency and orientation. Three types of link are proposed, namely, a chain of constructive links around sites of common spatial frequency but different orientation, constructive links between sites with common orientation but different spatial frequency, and long-range links between sites of common spatial frequency but different orientation. A model that employs the proposed network of links is shown to be consistent with at least six previously reported effects on the perception of briefly presented stationary plaids.
