Everything about Visual masking

Phenomenon of visual perception

Visual masking is a phenomenon of visual perception. It occurs when the visibility of one image, called a target, is reduced by the presence of another image, called a mask. The target might be invisible or appear to have reduced contrast or lightness. There are three different timing arrangements for masking: forward masking, backward masking, and simultaneous masking. In forward masking, the mask precedes the target. In backward masking the mask follows the target. In simultaneous masking, the mask and target are shown together. There are two different spatial arrangements for masking: pattern masking and metacontrast. Pattern masking occurs when the target and mask locations overlap. Metacontrast masking occurs when the mask does not overlap with the target location. A further type, object substitution masking, occurs when a sparse mask, such as four small dots surrounding the target, appears with the target and remains on screen after the target disappears. It is thought to depend on re-entrant processing from higher visual areas rather than on contour interactions. Wikipedia →
