Methods: Photographs were taken from the frontal view of 65 adults (35 women and 30 men) using stereophotogrammetry. Landmarks were identified by visual and manual examination and highlighted using a marker. All photographs were taken in NHP position. To evaluate photographs, Fourier analysis was performed after size normalization by setting area equal to a constant (25000 pixel).
Results:
Some Fourier coefficients were correlated to each other. The correlation between sampled and reconstructed curves of facial shape was 99 percent. The mean coefficients and facial indices were similar in both sexes.
Conclusions: No sexual dimorphism was observed in the facial shape.
