In our previous studies, we showed that monocular perception of 3D shapes is based on a priori constraints, such as 3D symmetry and 3D compactness. The present study addresses the nature of perceptual mechanisms underlying binocular perception of 3D shapes. First, we demonstrate that binocular performance is systematically better than monocular performance, and it is close to perfect in the case of three out of four subjects. Veridical shape perception cannot be explained by conventional…

Depth Cues Versus the Simplicity Principle in 3D Shape Perception

This study suggests that simplicity constraints, not depth cues, play the primary role in both monocular and binocular 3D shape perception, which is consistent with the computational model of3D shape recovery.
Perception of 3D Symmetrical and Nearly Symmetrical Shapes

The human visual system uses priors to convert an ill-posed inverse problem of 3D shape recovery into a well-posed one and it is shown that these priors can also be used to model perception of near-symmetrical shapes.
The visual perception of 3D shape from stereo: Metric structure or regularization constraints?
- Psychology
- 2017
Two experiments were conducted to evaluate people’s ability to disambiguate 3D shapes defined by binocular disparity within the ambiguity family that formed by stretching a 3D shape in depth using different stimuli and different tasks under different viewing conditions.

The results indicated that human observers are unable to compute the 3D shapes of complex, mirror-symmetric polyhedra whose symmetry planes were oriented at an angle of 45o relative to the line of sight in a shape-matching task.
Bilateral Symmetry Has No Effect on Stereoscopic Shape Judgments
- Physicsi-Perception
- 2021
A single experiment is reported that measured the apparent stereoscopic shapes of symmetric and asymmetric objects at different viewing distances and revealed that the apparent shapes of both types of objects were expanded or compressed in depth as a function of viewing distance, in exactly the same way as has been reported in many other studies.
Binocular 3D Object Recovery Using a Symmetry Prior

A new algorithm for 3D shape reconstruction from stereo image pairs that uses mirror symmetry as a biologically inspired prior is presented, allowing for straightforward recovery of occluded portions of the objects.

It is found that symmetry improves shape constancy for smooth 3D objects and suggest that one role of symmetry is to provide a reference orientation for an object.

Interestingly, monocular (but not binocular) reconstructions produced by this model correlate well with both monocular and binocular performance of human subjects, which suggests that binocular and monocular reconstructions of shapes in the human visual system involve similar mechanisms based on monocular shape constraints.

The results suggest that the percept of the shape of a 3D object is not based on the judgments of the 3-D orientations of the object's surfaces, but instead, the3-D shape percept is based on simplicity constraints.

There is a growing empirical consensus that MLE provides a good quantitative account of cue combination and that sensory information is used in a manner that maximizes the precision of perceptual estimates.
