GazeNeRF: 3D-Aware Gaze Redirection with Neural Radiance Fields

Ruzzi, Alessandro (author), Shi, X. (author), Wang, Xi (author), Li, Gengyan (author), De Mello, Shalini (author), Chang, Hyung Jin (author), Zhang, X. (author), Hilliges, Otmar (author)

We propose GazeNeRF, a 3D-aware method for the task of gaze redirection. Existing gaze redirection methods operate on 2D images and struggle to generate 3D consistent results. Instead, we build on the intuition that the face region and eyeballs are separate 3D structures that move in a coordinated yet independent fashion. Our method leverages...

Oxy-fuel combustion of coal pyrolysis gas has recently been proposed to serve as internal heat source of a vertical low-temperature pyrolysis furnace, in order to make the output pyrolysis gas nearly free of nitrogen and widely useful. To keep the pyrolysis temperature and the heat carrier gas volume unchanged from air combustion to oxy-fuel...
