A feedforward mechanism for human-like contour integration

Computational mechanisms underlying human contour integration.
(A) Low-level computations amplify responses to local elements that are part of a contour in the retinal image. This is facilitated by lateral connections between units with collinear tunings conceptualized as Association Fields (B) Mid-level feedforward computations focus on identifying potential candidates for an extended contour in the retinal image. This is facilitated by units with progressively increasing receptive fields (RFs) that are tuned to low orientation differences, allowing for the integration of local features into coherent extended contours.
