||Subjective contours capture stereopsis.
Eight experienced psychophysical observers who were unaware of the experiment's purpose were shown 4 configurations of a new class of stereograms. Results illustrate that monocular subjective contours can influence the matching of elements in a stereogram even though the elements themselves convey no disparity information. More specifically, the depth seen from such contours is automatically attributed to texture elements and lines that are enclosed by these contours--an illusion called stereoscopic capture. It is concluded that the brain may begin by segmenting the scene into contours and surfaces and that the information derived from such segmentation can have a profound influence on subsequent processing retinal disparities.
