Abstract
The induced effect refers to a visual phenomenon in which observers perceive a global stereoscopic slant about a vertical axis when the image presented to one eye is vertically magnified with respect to that presented to the other eye. This study proposed a computational model to account for stereoscopic depth perception including the induced effect, and tested this model using numerical simulations. In our model, we assumed that horizontal disparities were determined after correcting the overall size of two retinal images. Our model was able to predict the slant seen in the induced effect. Our simulation results indicate that the visual system corrects global stereo correspondence by using vertical size disparity before determining local horizontal disparities.
