MegaPortraits: One-shot Megapixel Neural Head Avatars. (arXiv:2207.07621v1 [cs.CV])

In this work, we advance the neural head avatar technology to the megapixel
resolution while focusing on the particularly challenging task of cross-driving
synthesis, i.e., when the appearance of the driving image is substantially
different from the animated source image. We propose a set of new neural
architectures and training methods that can leverage both medium-resolution
video data and high-resolution image data to achieve the desired levels of
rendered image quality and generalization to novel views and motion. We
demonstrate …
