Ollivier-Ricci Curvature For Head Pose Estimation From a Single Image. (arXiv:2204.13006v1 [cs.CV])

Head pose estimation is a crucial challenge for many real-world applications,
such as attention and human behavior analysis. This paper aims to estimate head
pose from a single image by applying notions of network curvature. In the real
world, many complex networks have groups of nodes that are well connected to
each other with significant functional roles. Similarly, the interactions of
facial landmarks can be represented as complex dynamic systems modeled by
weighted graphs. The functionalities of such systems are …
