Query: A cortical-inspired model for orientation-dependent contrast perception:
  a link with Wilson-Cowan equations   We consider a differential model describing neuro-physiological contrast
perception phenomena induced by surrounding orientations. The mathematical
formulation relies on a cortical-inspired modelling [10] largely used over the
last years to describe neuron interactions in the primary visual cortex (V1)
and applied to several image processing problems [12,19,13]. Our model connects
to Wilson-Cowan-type equations [23] and it is analogous to the one used in
[3,2,14] to describe assimilation and contrast phenomena, the main novelty
being its explicit dependence on local image orientation. To confirm the
validity of the model, we report some numerical tests showing its ability to
explain orientation-dependent phenomena (such as grating induction) and
geometric-optical illusions [21,16] classically explained only by
filtering-based techniques [6,18].
