Geometry Aware Facial Expression Translation

Geometry-aware facial expression translation aims to realistically alter facial expressions in images or videos, focusing on preserving accurate facial geometry and avoiding unwanted artifacts. Current research heavily utilizes Generative Adversarial Networks (GANs), often incorporating hierarchical structures or landmark guidance to achieve fine-grained control over expression changes and improve realism. This field is significant for its potential applications in animation, virtual reality, and assisting in the analysis of human emotion, particularly by enabling more accurate and nuanced manipulation of facial expressions in research datasets.
