These landmarks enabled us to intuitively characterize facial geometry at a fine level of detail through curvature measurements, yielding accurate heritability maps of the human face ( The human face is an important interface of social interaction communication, sensory input and expression in humans are to a large extent based on facial characteristics and traits 1. The algorithm places thousands of landmarks throughout the facial surface and automatically establishes point-wise correspondence across faces. High-resolution, three-dimensional facial models have been acquired on a cohort of 952 twins recruited from the TwinsUK registry, and processed through a novel landmarking workflow, GESSA (Geodesic Ensemble Surface Sampling Algorithm).
We present here a large-scale heritability study of face geometry that aims to address these issues. Furthermore, the construction of facial phenotypes that correspond to naturally perceived facial features remains largely a mystery. Nevertheless, heritability estimates of facial traits have often been surprisingly low or difficult to replicate.
The human face is a complex trait under strong genetic control, as evidenced by the striking visual similarity between twins.
