Monocular Depth Ordering using Perceptual Occlusion Cues

Babak Rezaeirowshan, Coloma Ballester, Gloria Haro
2016 Proceedings of the 11th Joint Conference on Computer Vision, Imaging and Computer Graphics Theory and Applications  
Monocular occlusion cues, namely, T-junctions and convexities, contain information suggesting a local depth order between neighbouring objects.  ...  The method we present stems from early vision cues such as occlusion and convexity and uses them to infer both a local and a global depth order.  ...  In order to integrate the partial depth orders suggested by the monocular depth cues we use a graph-based approach.  ...

Disambiguation of Necker cube rotation by monocular and binocular depth cues: Relative effectiveness for establishing long-term bias

Sarah J. Harrison, Benjamin T. Backus, Anshul Jain
2011 Vision Research  
In previous work, either binocular disparity and occlusion, or a combination of monocular depth cues that included occlusion, internal occlusion, haze, and depth-from-shading, were used to control the  ...  However, in a further experiment where only disambiguated cubes were presented on Day 1, perceptual outcome of ambiguous cubes during Day 2 counter-conditioning showed that the monocular-only cue set was  ...  monocular-only cue set (BM), and eight subjects received training and reverse-training using the reverse order of cue sets (MB).  ...

Illusory occlusion affects stereoscopic depth perception

Zhimin Chen, Rachel N. Denison, David Whitney, Gerrit W. Maus
2018 Scientific Reports  
Ordinal cues, such as occlusion, convey information about the ordering of objects in depth, but not about the metric depth of objects 7 .  ...  When the monocular bar was perceived as filled in through the blind spot, it was perceived as occluding the binocular bar, generating illusory occlusion.  ...  A 2IFC task was used to measure the perceived depth of the binocular bar and the monocular bar with illusory occlusion.  ...

The Contribution of Monocular Depth Cues to Scene Perception by Pigeons

Brian R. Cavoto, Robert G. Cook
2006 Psychological Science  
These results suggest that the pigeon visual system is sensitive to many of the same monocular depth cues that are known to be used by humans.  ...  The orderings of these objects were specified by the combined presence or absence of the pictorial cues of relative density, occlusion, and relative size.  ...  These results suggest that the pigeon visual system is sensitive to many of the same monocular depth cues that are known to be used by humans.  ...

Recovering Relative Depth from Low-Level Features Without Explicit T-junction Detection and Interpretation

Felipe Calderero, Vicent Caselles
2013 International Journal of Computer Vision  
This work presents a novel computational model for relative depth order estimation from a single image based on low-level local features that encode perceptual depth cues such as convexity/concavity, inclusion  ...  The validity of the proposed features and the integration approach is demonstrated by experiments on real images and comparison with state-of-the-art monocular depth estimation techniques.  ...  Monocular depth cues have been extensively studied by psychologist during the last century, using psycho-visual and perceptual studies (Howard 2012).  ...

Natural statistics of depth edges modulate perceptual stability

Near depth edges, some regions of a scene are often visible to only one eye (so-called half occlusions).  ...  occlusions.  ...  For example, a previous study that used photographs of real-world objects as stimuli (tabletop scenes with boxes) suggested that correct depth ordering judgments were facilitated for self occlusions as  ...

Natural image statistics at depth edges modulate perceptual stability [article]

Zeynap Basgoze, David N White, Johannes Burge, Emily A Cooper
2020 bioRxiv   pre-print
In particular, at depth edges parts of a scene are often visible to only one eye (so-called half occlusions).  ...  Exploiting regularities in natural environments may allow the visual system to facilitate fusion and perceptual stability of natural scenes when both binocular and monocular regions are visible.  ...  For example, a previous study that used photographs of real world 25 objects as stimuli (tabletop scenes with boxes) suggested that correct depth ordering 26 judgements were facilitated for self-occlusions  ...

Associative learning of shape as a cue to appearance: A new demonstration of cue recruitment

S. J. Harrison, B. T. Backus
2012 Journal of Vision  
The association of rotation direction and shape was only achieved when monocular depth cues were used to depict rotation in depth; shapes disambiguated by binocular disparity did not lead to recruitment  ...  of the shape cue.  ...  To anticipate our findings, we demonstrate that significant recruitment of the shape cue can be achieved, using the combined monocular depth cues of occlusion, selfocclusion, depth from shading, and haze  ...

Color for the perceptual organization of the pictorial plane: Victor Vasarely's legacy to Gestalt psychology

Birgitta Dresp-Langley, Adam Reeves
2020 Heliyon  
Current perception science explains such effects by invoking brain mechanisms for the processing of monocular (2D) depth cues.  ...  The figure-ground effects these configurations produce reveal a significant correlation between perceptual solutions for "nearer" and "bigger" when other geometric depth cues are missing.  ...  This monocular depth cue of relative size is perceptually reinforced by additional 2D cues of linear perspective ( Figure 1A ) and/or luminance contrast ( Figure 1B) , where the object with the lower  ...

Surface segmentation mechanisms and motion perception

John C. Trueswell, Mary M. Hayhoe
1993 Vision Research  
The tirst study explored how binocular disparity combines with monocular depth cues associated with transparency to determine whether subjects see one or multiple surfaces in depth in static displays.  ...  When transparency provided a depth cue that was consistent with binocular disparity, depth discrimination thresholds were at normal levels.  ...  One way of thinking about these elevations is as a measure of the "strength" of the monocular cues to depth order.  ...

Occlusion and the Interpretation of Visual Motion: Perceptual and Neuronal Effects of Context

Robert O. Duncan, Thomas D. Albright, Gene R. Stoner
2000 Journal of Neuroscience  
Such "extrinsic" features arise at occlusion boundaries and may be detected by virtue of the depth-ordering cues that exist at those boundaries.  ...  These neurons thus use contextual depth-ordering information to achieve a representation of the visual scene consistent with perceptual experience.  ...  The barber-diamond stimuli used in these experiments have, in addition to horizontal disparity, a second type of depth cue: monocular half-occlusions (see Materials and Methods).  ...

Enhancing Depth Perception in Translucent Volumes

Marta Kersten, James Stewart, Niko Troje, Randy Ellis
2006 IEEE Transactions on Visualization and Computer Graphics  
Surgeons make use of DRRs in planning and performing operations, so an improvement of depth perception in DRRs may help diagnosis and surgical planning.  ...  We present empirical studies that consider the effects of stereopsis and simulated aerial perspective on depth perception in translucent volumes.  ...  With opaque volumetric objects, shape and depth can be perceived when perceptual depth cues -such as shadows and shading, occlusion, perspective, and texture gradients -are used [9, 21] .  ...
