Topic: Facial symmetry


  
  Facial symmetry - Wikipedia, the free encyclopedia
Facial symmetry is one of a number of traits associated with health, physical attractiveness and beauty of a person or animal.
Facial asymmetries and minor physical anomalies begin to appear early in embryonic development, mainly the first trimester of pregnancy, and can be a sign of instability during this growth.
Facial symmetry is neither the only trait nor is it necessarily the most important trait of what the public subjectively considers attractive.

 Encyclopedia :: encyclopedia : Symmetry   (Site not responding. Last check: 2007-10-11)
Symmetry is a characteristic of geometrical shapes, equations, and other objects; we say that such an object is symmetric with respect to a given operation if this operation, when applied to the object, does not appear to change it.
A glide reflection symmetry (in 3D: a glide plane symmetry) means that a reflection in a line or plane combined with a translation along the line / in the plane, results in the same object.
Symmetry is also an important consideration in the formation of scales and chords, traditional or tonal music being made up of non-symmetrical groups of pitches, such as the diatonic scale or the major chord.

Symmetry is a characteristic feature of systems, geometrical shapes, equations, and other objects; we say that such an object is symmetric with respect to a given operation if this operation, when applied to the object, does not change it.
Considering points equivalent which, due to the symmetry, have the same properties, the equivalence classes are the orbits of the group action on the space itself.
Symmetry is used in the design of the overall floor plan of buildings as well as the design of individual building elements such as doors, windows, floors, frieze work, and ornamentation; many facades adhere to bilateral symmetry.

 Management of Facial Paralysis after Intracranial Surgery
Facial nerve is transected at surgery and grafted.
Facial nerve is anatommically intact but does not stimulate at the brainstem and there is no facial movement in the immediate postoperative period.
The facial nerve is identified as it courses from the stylomastoid foramen and is dissected peripherally distal to the point where the two major divisions of the faciai nerve are clearly identified.

 COMPUTATIONAL APPROACHES TO FACE RECOGNITION
The question, therefore, is whether an algorithm based on facial symmetry is sufficiently robust to be of value in identifying faces against a background of other objects.
The axis of symmetry was found by the symmetry axis algorithm described in the previous section: its output is shown as the white `blaze' through the nose of the image in Fig.
The effect of removal of this inhibitory component (and the symmetry axis constraint) is shown in column D of Figs.

Employ nerve substitution in patients with facial paralysis in which the proximal nerve segment is not available for repair or grafting, but a distal neuromuscular pathway is present, including an intact distal segment of nerve and facial musculature suitable for reinnervation.
Facial tone and symmetry were noted in all patients undergoing jump grafting, with good movement in 41%, and less synkinesis than those undergoing direct grafting.
Facial motor function generally is not as strong following a jump graft, and recovery of facial function was found to take longer in jump grafts than direct grafts, with movement not seen in some patients until 24 months postoperatively.

Studies on the role of the babyface scheme for human facial attractiveness were conducted in a seventh experimental series.
The results of our symmetry experiments show a clear but only weak relationship between facial attractiveness and symmetry: very asymmetrical faces are rated unattractive, but unattractive faces don't need to be asymmetrical.
In terms of facial proportions, this means that the 'attractiveness is averageness' hypothesis is clearly falsified.

It is difficult to produce an isolated contraction of the facial muscles using electrical stimulation due to their small size and close proximity to each other.
The ineffectiveness of traditional therapy methods for facial paralysis stems from their non-specificity and lack of adaptation to the unique characteristics of facial muscle.
Facial muscle appears to resist degeneration post denervation for longer periods of time than other skeletal muscle, and may remain viable for three or more years.

stated that "any analysis based on cephalometric or facialnormative’ values has one inherent weakness, and that is that beauty is not the norm." Indeed, if facial esthetics were regarded as falling along a normal distribution, i.e., on a bell curve, beauty would fall in the far-right portion of the curve.
Marquardt has developed a set of "facial masks" that can be superimposed over facial photographs, frontal or lateral, of individual patients for the assessment of the fit of their face to an idealized symmetry based on the golden decagon matrix (Figure 2).
Individualized assessment of facial balance and symmetry is then accomplished by analyzing the relationships of these four centroids to Ba-A and the centroid plane.

Videotapes of you engaged in normal conversation and facial expressions are helpful in monitoring patterns of muscle use and smile configuration before and after your surgery.
In long-standing cases of total facial paralysis, a second stage procedure is used to microsurgically transfer a fresh muscle from the inner thigh to replace the paralyzed smile muscle and receive the nerve impulse from the cross facial nerve graft.
Outcomes are not entirely predictable, but in almost all cases facial balance and symmetry is restored by the static resuspension and a substantial degree of voluntary smile activity and facial expression is achieved.

 Symmetry and perceived facial attractiveness: a monozygotic co-twin comparison   (Site not responding. Last check: 2007-10-11)
Investigating the nature of this relationship has been difficult, however, for several reasons, including the facts that variance in symmetry is attributable to more than one source and is often correlated with other variables related to attractiveness.
This study assessed the role of facial symmetry in relation to perceptions of facial attractiveness.

Facial asymmetry is a natural thing, and is far more common than facial symmetry, but you don't really see it unless you're looking for it.
Facial symmetry does exist, but it is very rare, and when we see it, we call it "beautiful".
Draw the left eye, and when you come to the right eye, don't just draw the mirror image of the left, because, chances are that the right looks different than the left.

Across cultures (based on a study of Japanese and U.S. observers' judgements of female attractiveness), high cheekbones, a thin lower jaw, large eyes, and a shorter distance between the mouth and chin (and between the nose and mouth) are preferred as "cute" qualities in men's and women's faces alike (Perrett, May, and Yoshikawa 1994).
Another preferred trait may be facial symmetry between the right and left sides.
In a review of symmetry in mate selection, researchers found that animals from scorpion flies to zebra finches showed a preference for symmetrical patterns and shapes (perhaps because asymmetry is a sign of weakness or disease; Watson and Thornhill 1994).
