Cortical dynamics of three-dimensional form, color, and brightness perception. 2. Binocular theory
A real-time visual-processing theory is developed to explain how three-dimensional form, color, and brightness precepts are coherently synthesized. The theory describes how several fundamental uncertainty principles that limit the computation of visual information at individual processing stages are resolved through parallel and hierarchical interactions among several processing stages. The theory provides a unified analysis and many predictions of data about stereopsis, binocular, rivalry, hyperacuity, McCollough effect, textural grouping, border distinctness surface perception, monocular and binocular brightness precepts, filling-in, metacontrast, transparency, figural aftereffects, lateral inhibition within spatial frequency channels, proximity-luminance covariance, tissue contrast, motion segmentation, and illusory figures, as well as about reciprocal interactions among the hyper-columns, blobs, and stripes of cortical areas V1, V2, and V4. Monocular and binocular interactions between a Boundary Contour (BC) system and a Feature Contour (FC) System are developed. The BC System, defined by a hierarchy of oriented interactions, synthesizes an emergent and coherent binocular boundary segmentation from combinations of unoriented and oriented scenic elements.
