Facial Prior

Facial priors are pre-existing knowledge about facial structure and appearance used to improve the performance of various computer vision tasks, such as face super-resolution, restoration, and generation. Current research focuses on integrating these priors into deep learning models, particularly generative adversarial networks (GANs) and diffusion models, often employing techniques like attention mechanisms and hypernetworks to effectively leverage this information. This research is significant because accurate and efficient facial prior utilization leads to improved image quality and more robust performance in applications ranging from facial recognition to affective behavior analysis and 3D face reconstruction.
