First- and second-order contributions to depth perception in anti-correlated random dot stereograms [article]

Jordi M Asher, Paul B Hibbard
2018 bioRxiv   pre-print
Depth was mostly perceived in the correct direction for ACRDS edge stimuli, with the effect increasing with the gap size.  ...  The mixed findings may be accounted for by the presence of a gap between the target and surround, or as a result of overlap of dots around the vertical edges of the stimuli.  ...  This similarity matching can for example be based on the correlation of local intensity values.  ...
