Abstract: We describe two psychophysical experiments testing predictions of the square difference mechanism proposed for intensity-based stereo in an earlier paper (Arndt et al. 1995). Experiment1 assesses the relative contributions of disparity and contrast to intensity-based stereo by
measuring detection thresholds. The product of disparity and contrast at threshold is shown to be constant. In Experiment 2, we measure quantitatively the global depth position perceived in stereograms of curved, smoothly shaded surfaces. The results show that disparity
averaging over the surface involves a contrast dependent weighting function. The results from both experiments are consistent with predictions derived from the square difference mechanism. The relation of this mechanism to feature correspondence stereopsis and
shape-from-shading is discussed and a general framework for
assessing the modularity of stereopsis is presented.
