Bilateral symmetry in vision and influence of ocular surgical procedures on binocular vision: A topical review

open access: yesJournal of Optometry, 2016
We analyze the role of bilateral symmetry in enhancing binocular visual ability in human eyes, and further explore how efficiently bilateral symmetry is preserved in different ocular surgical procedures. The inclusion criterion for this review was strict

Bilateral lower limb symmetry during sit-to-stand and stand-to-sit tasks in stroke patients with hemiplegia

open access: yesFrontiers in Neurology
IntroductionStroke patients with hemiplegia are at an increased risk of falling during sit-to-stand (Si-St) and stand-to-sit (St-Si) tasks, partly due to impaired bilateral lower limb symmetry.

Application of symmetry evaluation to deep learning algorithm in detection of mastoiditis on mastoid radiographs

open access: yesScientific Reports, 2023
As many human organs exist in pairs or have symmetric appearance and loss of symmetry may indicate pathology, symmetry evaluation on medical images is very important and has been routinely performed in diagnosis of diseases and pretreatment evaluation ...

Aging and Bilateral Symmetry Detection [PDF]

open access: yesThe Journals of Gerontology Series B: Psychological Sciences and Social Sciences, 2002
The salience of bilateral symmetry varies as a function of the orientation of the symmetry axis. Vertical symmetry is most salient, followed by horizontal and then oblique orientations. We tested symmetry detection in different age groups to determine whether performance of this intermediate-level visual task is affected by normal, nonpathological ...

Patterns of Symmetry Expression in Angiosperms: Developmental and Evolutionary Lability

open access: yesFrontiers in Ecology and Evolution, 2020
Variation in flower symmetry is a remarkable aspect of flowering plant diversity. Multiple evolutionary transitions from an ancestral form of radial symmetry to bilateral symmetry and reversals from bilateral to radial symmetry have occurred during ...

Bilateral Symmetry before and Six Months after Aberration-Free™ Correction with the SCHWIND AMARIS TotalTech Laser: Clinical Outcomes

open access: yesJournal of Optometry, 2010
Purpose: To compare the preoperative and postoperative bilateral symmetry between OD and OS eyes that have undergone femto-LASIK using the Ziemer LDV femtosecond laser system, the SCHWIND AMARIS Excimer Laser and the Aberrationfree™ profiles implemented ...

The manoeuvrability hypothesis to explain the maintenance of bilateral symmetry in animal evolution

open access: yesBiology Direct, 2012
Background The overwhelming majority of animal species exhibit bilateral symmetry. However, the precise evolutionary importance of bilateral symmetry is unknown, although elements of the understanding of the phenomenon have been present within the ...

Morphology and the gradient of a symmetric potential predicts gait transitions of dogs [PDF]

open access: yes, 2017
Gaits and gait transitions play a central role in the movement of animals. Symmetry is thought to govern the structure of the nervous system, and constrain the limb motions of quadrupeds. We quantify the symmetry of dog gaits with respect to combinations

Fast Radial and Bilateral Symmetry Detection Using Inverted Gradient Hash Maps

open access: yesEAI Endorsed Transactions on Context-aware Systems and Applications, 2017
This paper presents a fast and novel algorithm for both radial and bilateral symmetry detection based on inverted gradient hash maps (IGHMs). A hash map is an associative array that stores image gradient magnitudes and orientations in the form of an ...
