In the science of visual perception, stereopsis is the sensation that objects in space extend into depth, and that objects have different distances from each other. This sensation is much stronger than the suggestion of depth that is created by two-dimensional perspective.

In the science of visual perception, stereopsis is the sensation that objects in space extend into depth, and that objects have different distances from each other. This sensation is much stronger than the suggestion of depth that is created by two-dimensional perspective.
In humans, at least two mechanisms produce the sensation of stereopsis: binocular depth vision and (monocular) motion vision. In binocular depth vision, the sensation arises from processing differences in retinal images resulting from the two eyes looking from different, but similar, directions (binocular disparity). In motion vision, the sensation arises from processing motion information when the observer moves (e.g. optical flow, parallax). The sensation of stereopsis is similar in both cases.
