Filling-in by foveal vision

Perceptual filling-in of artificially induced scotomas during steady eccentric fixation is well-known, but the author found that humans also perceive color filling-in of foveated figures during fixation. The author examined a stereoscopic view of these images with different central figures. As the filling-in progressed, the stereoscopic view disappeared. The author investigated not only equiluminant color combinations but also textured patterns and motion patterns under equiluminant conditions. In the latter cases, the filling-in was not as complete as the color filling-in. The author´s model of color filling-in involves two edge detectors, one for color and another for brightness. When the color edge detector produces no output, having not been activated by the brightness edge detector for several seconds, then color information is transmitted across the border from each side.
