Vision science

One surface hiding another as a depth cue

In vision science, occlusion is the blocking of one surface by another nearer to the viewer, a powerful depth cue because the object that hides part of another is seen as closer, while the visual system fills in the hidden portions to recognise whole objects. Nakayama, Shimojo, and Silverman's 1989 study related stereoscopic depth to how the visual system segments scenes and recognises partly occluded objects. The referent is a spatial relationship between surfaces and the inferences the brain draws from it, unrelated to a blocked artery or the meeting of teeth beyond the common thread of one thing covering another.[1]
