A novel illusion of bars made from triangles |
|
| Authors: | Leguire L E Blake R Sloane M E |
| Abstract: | A repetitive pattern of a triangular luminance profile may be perceived as a triangular-wave grating or as a square-wave grating. This illusion may reflect the operation of cortical phase-selective mechanisms that are biased toward particular phase relations and favor abrupt luminance gradients. |
