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.

Symmetry in Healing After Bilateral Eyelid Surgery

Ophthalmic Plastic & Reconstructive Surgery, 2006
To determine whether surgery performed bilaterally (ptosis repair, blepharoplasty, or both) results in symmetric healing.Case series of 19 consecutive patients undergoing bilateral ptosis repair, blepharoplasty, or both. Patients were provided with questionnaires to determine their perception of the degree of symmetry in healing at four time points ...

Detection of bilateral symmetry using spatial filters

Spatial Vision, 1994
When bilaterally symmetric images are spatially filtered and thresholded, a subset of the resultant 'blobs' cluster around the axis of symmetry. Consequently, a quantitative measure of blob alignment can be used to code the degree of symmetry and to locate the axis of symmetry.

Modelling the Bilateral Symmetry of Caries Incidence

Caries Research, 2008
<i>Background/Aims:</i> Past caries experience has been shown to be the best predictor of the development of caries in the future, and clinical observations suggest that caries develops symmetrically in similar teeth on each side of the mouth.

Bilateral Symmetry Detection: Testing a ‘Callosal’ Hypothesis

Perception, 1996
At the end of the 19th century Mach observed that vertical symmetry is more easily perceived than is symmetry at other orientations, and proposed this resulted from bilateral symmetry in the visual system. Numerous studies of symmetry detection have been conducted, but none has been concentrated on Mach's proposal.

Bilateral Symmetry of Morphologic Lesions in Alzheimer's Disease

Archives of Neurology, 1988
We studied 16 brains of patients with Alzheimer's disease for left-right differences, or similarities, in the density of senile plaques (SPs) or neurofibrillary tangles (NFTs). Counts were made of SPs and NFTs on the left and right side of five different brain areas, which included middle frontal, superior temporal, the prosubiculum of the hippocampus (
