Facial shape affects self-perceived facial attractiveness
Fig 5
a. PCA graph displaying facial shape variation in males (in SD units), as explained by PC1 (20%) and PC2 (16.8%). The corresponding 3D facial morphings show the shape extremes from -3 to +3 standard deviations of PC scores within each axis. b. Best fit superimpositions of shape transformations created from the Procrustes coordinates corresponding to -3SD and +3SD of PC scores within each axis from the average shape configuration in the male population. The superimpositions display the direction of shape variation explained by each PC.
