Binocular 3D Object Recovery Using a Symmetry Prior

Binocular 3D Object Recovery Using a Symmetry Prior

We present a new algorithm for 3D shape reconstruction from stereo image pairs that uses mirror symmetry as a biologically inspired prior. 3D reconstruction requires some form of prior because it is an ill-posed inverse problem. Psychophysical research shows that mirror-symmetry is a key prior for 3D shape perception in humans, suggesting that a general purpose solution to this problem will hav...

3d Volumetric Object Perception in Binocular Vision

3D object perception is one of the important issues in the study of human visual functions. It is a seemingly effortless process that requires no conscious thought for the human beings, but a difficult computational problem for machines. The object perception with binocular viewing utilizes the disparities between the two eyes to recover the 3D information of an object, and takes the advantages...

3d Object Symmetry Measurement Using Extended Gaussian Image

In this paper, we state a new way for measuring symmetry of three-dimensional graphic object. The idea is based on the representation of three-dimensional objects by their Extended Gaussian Image (EGI). The EGI is constructed by mapping each surface normal of any object to the Gaussian sphere. The Gaussian sphere is presented by icosahedrons and 60 rotations are applied. An experimental evaluat...

A Symmetry Prior for Convex Variational 3D Reconstruction

Recovery from monocular deprivation using binocular deprivation.

Ocular dominance (OD) plasticity is a robust paradigm for examining the functional consequences of synaptic plasticity. Previous experimental and theoretical results have shown that OD plasticity can be accounted for by known synaptic plasticity mechanisms, using the assumption that deprivation by lid suture eliminates spatial structure in the deprived channel. Here we show that in the mouse, r...
