Random-dot stereograms of an object standing out from a background always contain a monocular region at the side of the foreground object. This is equivalent to the monocularly occluded part of the background in the real-life viewing of one object in front of another. The role of these monocular regions in the stereoscopic process has not been investigated previously, although it is generally assumed that they are a source of difficulty in stereoscopic resolution because of the unmatchable…

The role of partial occlusion in stereopsis

MODELS of stereopsis typically assume that all the information about stereoscopic depth is contained in the disparity field, that is, the positional differences of image features that arise from

Toward a general theory of stereopsis: binocular matching, occluding contours, and fusion.

The authors hypothesize the existence of receptive field structures that sense the local structure of stereoscopic occlusion relationships to account for these findings and present a simple theoretical framework in which fusion, stereopsis, and Occlusion are unified.

Monocular zones in stereoscopic scenes: A useful source of information for human binocular vision?

Evidence is discussed, from knowledge of human visual perception, illustrating that monocular zones do not pose problems for the authors' human visual systems, rather, their visual systems can extract depth from such zones.

Local Detection of Stereo Occlusion Boundaries

The local detector for stereo occlusion boundaries is introduced based on a simple feedforward network with relatively small receptive fields and produces better boundaries than many other stereo methods, even without incorporating explicit stereo matching, top-down contextual cues, or single-image boundary cues.

Toward Perceptually-Consistent Stereo: A Scanline Study

This work represents a disparity profile as a piecewise smooth function with explicit breakpoints between its smooth pieces, and shows this allows correlation and decorrelation to be integrated into an objective that requires only two types of local information: the correlation and its spatial gradient.

Sensitivity to Monocular Occlusions in Stereoscopic Imagery: Implications for S3D Content Creation, Distribution and Exhibition

The geometric basis of monocular occlusions and their role in natural depth perception is reviewed and the reconstruction of novel and appropriate viewpoints from sequences of 2D images from one or more vantage points is framed.

Global patterns of binocular image differences resolve the ambiguity between stereoscopic slant and stereoscopic occlusion

A number of findings have clearly indicated that monocular details contribute to binocular depth perception, but there are binocular stimulus conditions that are ambiguous with respect to whether monocular regions exist or not.

Depth from Binocular Half-Occlusions in Stereoscopic Images of Natural Scenes

The results show that depth-ordering judgments for these relatively complex stimuli are significantly affected by the nature of the half-occlusion signal, but only when highly textured surfaces are viewed.
