Modeling the Combination of motion, Stereo, and Vergence Angle Cus to Visual Depth

摘要

Three models of visual cue combination were simulated: a weak fu- sion model, a modified weak model, and a strong model. Their relative strengths and weaknesses are evaluated on the basis of their performances on the tasks of judging the depth and shape of an ellipse. The models dif- fer in the amount of interaction that they permit among the cues of stereo, motion, and vergence angle. Results suggest that the constrained nonlin- ear interaction of the modified weak model allows better performance than either the linear interaction of the weak model or the unconstrained nonlinear interaction of the strong model.
