Bilateral Symmetry Detection via Symmetry-Growing

Procedings of the British Machine Vision Conference 2009, 2009
We present a novel and robust method for localizing and segmenting bilaterally symmetric patterns from real-world images. On the basis of symmetrically matched pairs of local features, our method expands and merges condent local symmetric region matches by exploiting both photometric similarity and geometric consistency via our new symmetry-growing ...

Interocular symmetry analysis of bilateral eyes

Journal of Medical Engineering & Technology, 2014
The purpose of this study was to evaluate the interocular symmetry of several biometric parameters between both eyes. The symmetry between the right and left eye of 397 subjects in 14 biometric parameters, spherical equivalent of refractive error (SE), Jackson crossed cylinder power of refractive error astigmatism with axes at 90° and 180° (RJ0) and at

Bilateral symmetry analysis of breast MRI

Physics in Medicine and Biology, 2003
Mammographic interpretation often uses symmetry between left and right breasts to indicate the site of potential tumour masses. This approach has not been applied to breast images obtained from MRI. We present an automatic technique for breast symmetry detection based on feature extraction techniques which does not require any efforts to co-register ...

Physiological Correlates of Bilateral Symmetry in Humans

International Journal of Sports Medicine, 2000
Departures from perfect bilateral symmetry are thought to mirror an organism's ability to maintain developmental homeostasis. There is evidence showing that symmetry is negatively correlated with evolutionary and physical fitness. The purpose of this study was to determine the relationship between symmetry and health-related physiological ...

Bilateral Symmetry and Perceptual Reversals

Perception, 2014
Imposition of patterns varying in symmetry about the observer's median plane on a reversible figure affects duration for which each of the fluctuating percepts is experienced. Symmetry of the imposed patterns is associated with lesser difference between the two durations.

Line-drawing interpretation: bilateral symmetry

IEEE Transactions on Pattern Analysis and Machine Intelligence, 1989
Results previously derived by the author are used to investigate the implication of bilateral symmetry in line drawings. It is shown that the line drawing of an orthographically protected surface of revolution exhibits bilateral symmetry about the projection of its axis of revolution irrespective of the viewing direction.

Detecting Bilateral Symmetry in Perspective

2006 Conference on Computer Vision and Pattern Recognition Workshop (CVPRW'06), 2006
A method is presented for efficiently detecting bilateral symmetry on planar surfaces under perspective projection. The method is able to detect local or global symmetries, locate symmetric surfaces in complex backgrounds, and detect multiple incidences of symmetry.

Bilateral symmetry in crayfish behavioral reactions

Acta Biologica Hungarica, 2008
The crayfish, Procambarus cubensis, placed in the central area of a plus-maze preferred to go forward in about 50% of trials; they chose the right or left arm in 20.7 and 18.9% of the trials, respectively. In a T-maze, the difference between right and left directions was also insignificant. When exploring a plus-maze, the crayfish turned to 180 degrees

OPTIMIZED QUANTITATIVE BILATERAL SYMMETRY DETECTION

International Journal of Information Acquisition, 2005
In [Westhoff et al., 2005], we proposed a novel method to determine illumination-invariant features in images. The quantitative bilateral symmetry of a given scene is computed using dynamic programming before applying the resulting symmetry image and feature vector signatures to an omnidirectional motion tracking task.
