A new look at binocular stereopsis
We report a new phenomenon, which illustrates that the role of binocular disparity in 3D shape perception critically depends on whether the parts are interpreted as belonging to a single object. The nature of this phenomenon was studied in four experiments. In the first two experiments the subjects were shown a sequence of stereoscopic images of a cube, in which binocular disparity indicated th...
متن کاملConfiguration stereopsis: a new look at the depth-disparity relation.
Recovering shape in three dimensions has obvious importance for visual perception. Hence one principal goal for stereopsis should be to recover good estimates of 3D shape. But this is impossible if disparity processing is hardwired, because at different fixation distances a fixed angular disparity will correspond to quite different distance increments. An experiment confirms previous evidence t...
متن کاملBinocular Helmholtz Stereopsis
Helmholtz stereopsis has been introduced recently as a surface reconstruction technique that does not assume a model of surface reflectance. In the reported formulation, correspondence was established using a rank constraint, necessitating at least three viewpoints and three pairs of images. Here, it is revealed that the fundamental Helmholtz stereopsis constraint defines a nonlinear partial di...
متن کاملStereopsis and binocular rivalry.
Stereopsis and binocular rivalry appear to be incompatible. Rivalry involves suppression of input from one eye at each location in space and time, whereas Stereopsis requires the combination of information from both eyes to yield a sensation of depth. This article presents a theory of the relationship of these phenomena. Evidence from previous work and from experiments reported here shows that ...
متن کاملGlobal Priors for Binocular Stereopsis
In this paper, we develop a Bayesian feedback method for incorporating global structure into prior models for binocular stereopsis. Since most stereo scenes contain either background continuation (large background surfaces continuing behind smaller foreground surfaces) or transparency continuation (small opaque patches on a transparent surface), highly nonlocal interactions are often present in...
