 Abstract: Correpondence is often considered the crucial problem in binocular stereopsis. It consists in finding the images of the same object in the two half--images of a stereogram. With correspondence solved, depth can be determined by triangulation. However, half--images differ in a number of other ways as well, which might be useful for depth perception without involving correspondence. Using intensity--based stereo and disparity--evoked vergence as examples, I will show that in these cases interocular correlation is a more likely mechanism than the purely geometrical notion of correspondence. In conclusion, a task--oriented view of stereopsis is presented. Correlation subserves relatively simple tasks such as depth ordering or vergence control, whereas correspondence is needed for fine depth resolution and figure--ground segmentation (camouflage breaking).
