Abstract

This paper introduces the 3D Face Gravitational Morphing to elevate the performance of Deep Learning models in the realm of 3D facial classification. Addressing the constraints imposed by small-scale datasets, our approach amplifies intra-class variability while maintaining the semantic fidelity of 3D models. This is accomplished by generating shapes within the proximity of the original models in the context of shape space, facilitated by a curvature-based correspondence. The integration of Face Gravitational Morphing into the architecture is demonstrated through its application to the BU3DFE dataset for classification purposes. A comparative analysis reveals the method’s relative performance, representing an initial step towards mitigating limitations in facial classification. Ongoing investigations are underway to refine and extend these promising results.
