From: Depth perception of stereoscopic transparent stimuli with frame manipulation

The mean perceived depths as a function of the number of surfaces of a POTS configuration for the small, medium, and large disparity conditions. The blue rhombus, green circle, red triangle, and orange square show the results of the frameless, large-frame, medium-frame, and small-frame conditions, respectively. Error bars signify the 95% confidence interval. The blue and pink cross marks indicate the geometrical prediction and the prediction from empirical data, respectively, as in Fig. 1.
