Interocular symmetry analysis of bilateral eyes
Journal of Medical Engineering & Technology, 2014The 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

Achieving bilateral symmetry during vertebrate limb development
Seminars in Cell & Developmental Biology, 2009While the various internal organs of vertebrates display many obvious left-right asymmetries in their location and/or morphology, external features exhibit a high degree of bilateral symmetry. How this external bilateral symmetry is established during development is largely unknown.

Bilateral flower symmetry—how, when and why?
Current Opinion in Plant Biology, 2014Bilateral flower symmetry has evolved multiple times during flowering plant diversification, is associated with specialized pollination, and is hypothesized to have contributed to flowering plant species richness. The genes and genetic interactions that control bilateral symmetry are well understood in the model species Snapdragon (Antirrhinum majus ...

Bilateral Symmetry Detection via Symmetry-Growing
Procedings of the British Machine Vision Conference 2009, 2009We 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 ...

Bilateral symmetry analysis of breast MRI
Physics in Medicine and Biology, 2003Mammographic 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, 2000Departures 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, 2014Imposition 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, 1989Results 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.
