Abstract

The smoothness constraint can bias the binocular matching solution for several adjacent targets when each target has several potential matches. The smoothness matching solution favors the smallest disparity difference between adjacent targets. Previously, we have shown that the smoothness matching bias increases with spatial proximity of adjacent targets (Zhang et al, 2001). Here we test the influence of several surface texture properties including contour orientation, spatial phase and spatial frequency on the matching solution. Subjects judged the sign of perceived depth of a center Gabor patch flanked above and below by two Gabors of opposite sign disparity. The similarity of surface features between the center and flanking Gabors was varied to determine the influence of each texture property on the binocular matching solution. Results indicate that random spatial phase between texture elements in adjacent patches does not favor the smoothness solution. Continuity of contours between patches had the largest affect on the smoothness matching solution. These results demonstrate that a consistent pattern of spatial phase between surface elements in adjacent patches promotes the smoothness matching solution. Ref: Zhang et al. (2001) Spatial interactions minimize disparity differences between adjacent surfaces. Vision Research 41: 2995–3007
