Three-dimensional (3D) shape has been studied for centuries despite the absence of a
commonly accepted definition of this property. The absence of a useful definition has been a …

This paper reviews recent progress towards understanding 3D shape perception made
possible by appreciating the significant role that veridicality and complexity play in the natural …

This study examined the ability of human observers to discriminate between symmetric and
asymmetric planar figures from perspective and orthographic images. The first experiment …

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 …

This study tested perception of symmetry of 3D shapes from single 2D images. In Experiment
1, performance in discrimination between symmetric and asymmetric 3D shapes from …

The human visual system uses priors to convert an ill-posed inverse problem of 3D shape
recovery into a well-posed one. In previous studies, we have demonstrated the use of priors …

In this paper, we take up the long-standing problem of how to recover 3-D shapes represented
by a 2-D image, such as the image on the retina of the eye, or in a video camera. Our …

In this note, we are commenting on a paper by Sugihara and Pinna (2022, referred to as
SP22 in this note) published in Frontiers in Human Neuroscience. SP22 discussed the role of …

Symmetry has been shown to be a very effective a priori constraint in solving a 3D shape
recovery problem. Symmetry is useful in 3D recovery because it is a form of redundancy. There …

The evidence for the use of Augmented Reality (AR) in treating specific phobias has been
growing. However, issues of accessibility persist, especially in developing countries. The …
