Searching for Radial Symmetry [PDF]
Symmetry is ubiquitous in the natural world. Numerous investigations, dating back over one hundred years, have explored the visual processing of symmetry. However, these studies have been concerned with mirror symmetry, overlooking radial (or rotational)

Minimax Density Estimation Under Radial Symmetry
This study illustrates a dimensionality reduction effect of radial symmetry in nonparametric density estimation. To deal with the class of radially symmetric functions, we adopt a generalized translation operation that preserves the symmetry structure ...

Radial symmetry in a chimeric glutamate receptor pore. [PDF]
Ionotropic glutamate receptors comprise two conformationally different A/C and B/D subunit pairs. Closed channels exhibit fourfold radial symmetry in the transmembrane domain (TMD) but transition to twofold dimer-of-dimers symmetry for extracellular ligand binding and N-terminal domains.

Radial Symmetry Does Not Preclude Condorcet Cycles If Different Voters Weight the Issues Differently
Radial symmetry, by our definition, is a precise condition on continuous ideal-point distributions, rarely if ever found exactly in practice, that is similar to the classical 1967 symmetry condition of Plott but pertains to an infinite electorate; the ...

On radial symmetry of rotating vortex patches in the disk
In this note, we consider the radial symmetry property of rotating vortex patches for the 2D incompressible Euler equations in the unit disc. By choosing a suitable vector field to deform the patch, we show that each simply-connected rotating vortex patch $D$ with angular velocity $Ω$, $Ω\geq \max\{{1}/{2},({2 l^2})/{(1-l^2)^2}\}$ or $Ω\leq -({2 l^2})/{

On the approximation of the elastica functional in radial symmetry [PDF]
The aim of the paper is to begin the analysis of the \(\Gamma\)-limit in \(L^1_{\text{loc}}({\mathbb R}^n)\), as \(\varepsilon\to0\), of the sequence of the functionals \[ {\mathcal F}_\varepsilon(v)=\begin{cases} \int_{{\mathbb R}^n}\left[m_\varepsilon(v)+\varepsilon^{-1}(\text{ eul}_\varepsilon(v))^2\right]dx &\text{if }v\in H^2_{\text{loc}}({\mathbb

Fast radial symmetry for detecting points of interest
A new transform is presented that utilizes local radial symmetry to highlight points of interest within a scene. Its low-computational complexity and fast runtimes makes this method well-suited for real-time vision applications. The performance of the transform is demonstrated on a wide variety of images and compared with leading techniques from the ...

A new radial symmetry measure applied to photogrammetry
This work presents a new measure for radial symmetry and an algorithm for its computation. This measure identifies radially symmetric blobs as locations with contributions from all orientations at some scale. Hence, at a given scale, radial symmetry is computed as the product of the responses of a set of even symmetric feature detectors, with different
