The Hermann grid illusion consists of smudges perceived at the intersections of a white grid
presented on a black background. In 1960 the effect was first explained by a theory …

been found to depend on the spatial frequency of the stimulus, are due to precortical …

Grid illusions, including the Hermann grid and scintillating grid (in which light disks are
superimposed upon the grid intersections), are diminished by curving the alleys that limn the …

To improve robustness in object recognition, many artificial visual systems imitate the way in
which the human visual cortex encodes object information as a hierarchical set of features …

The scintillating grid illusion is an intriguing stimulus consisting of a grey grid on a black
background, with white discs at the grid intersections. Most viewers perceive illusory …

The study is devoted to the study of the manifestations of the scintillating grid illusion in
patients with amblyopia. Overall, 133 schoolchildren with bilateral refractive amblyopia and …

In a classic Hermann grid display, faint and transient (illusory) spots are produced at the
intersections of a white grid superimposed on a black background (or vice versa). In a …

When observers view a grid of mid-gray lines superimposed on a black background, they
report seeing illusory dark gray smudges at the grid intersections, an effect known as the …

Adaptive psychophysical methods require a reference stimulus and are difficult to evaluate
nonlinear perceptual relationships and impressions within a visual design. This study …

We report a new illusion in which the edges of diamonds placed at the intersections of grids
are perceived to be jaggy (the jaggy diamonds illusion). Interestingly, the illusion disappears …
