Finding Mirror Symmetry via Registration

no code implementations18 Nov 2016 Marcelo Cicconet, David G. C. Hildebrand, Hunter Elliott

This new Mirror Symmetry via Registration (MSR) framework involves (1) data reflection with respect to an arbitrary plane, (2) registration of original and reflected datasets, and (3) calculation of the eigenvector of eigenvalue -1 for the transformation matrix representing the reflection and registration mappings.

Quantum Pairwise Symmetry: Applications in 2D Shape Analysis

no code implementations2 Feb 2015 Marcelo Cicconet, Davi Geiger, Michael Werman

A pair of rooted tangents -- defining a quantum triangle -- with an associated quantum wave of spin 1/2 is proposed as the primitive to represent and compute symmetry.

Complex-Valued Hough Transforms for Circles

no code implementations2 Feb 2015 Marcelo Cicconet, Davi Geiger, Michael Werman

This paper advocates the use of complex variables to represent votes in the Hough transform for circle detection.

A Geometric Descriptor for Cell-Division Detection

no code implementations15 Jan 2013 Marcelo Cicconet, Italo Lima, Davi Geiger, Kris Gunsalus

We describe a method for cell-division detection based on a geometric-driven descriptor that can be represented as a 5-layers processing network, based mainly on wavelet filtering and a test for mirror symmetry between pairs of pixels.
