3d facial signal imaging
6 Mar Due to the rapid progress of facial imaging and analysis technology, especially the 3D dense face model-based approaches, complex facial shape traits are Nevertheless, the facial signals of social attributes are more difficult to study due to the involute and highly subjective nature of social attributes.

Description:However, direct evidence of association between facial shapes and personality is missing from the current literature. Dense anatomical correspondence was established across the 3D facial images in order to allow high-dimensional quantitative analyses of the facial phenotypes. We used composite partial least squares component CPSLC to test association between the self-tested personality scores and the dense 3D facial image data, then used principal component analysis PCA for further validation. Among the five personality factors, agreeableness and conscientiousness in males and extraversion in females were significantly associated with specific facial patterns. The personality-related facial patterns were extracted and their effects were extrapolated on simulated 3D facial models. Introduction As one of the most complex anthropological traits, the human facial shape is strongly regulated by many factors such as genetics, ethnicity, age, gender, and health.
