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...

Influence of liquid-binder ratio on the performance of alkali-activated slag mortar with superabsorbent polymer

Yang, Zhengxian (author), Shi, Peng (author), Zhang, Yong (author), Li, Z. (author)

The influences of liquid-binder ratio and mixing sequence on the performance of superabsorbent polymer (SAP)-containing alkali-activated slag (AAS) mortar are investigated in this study. It is found that the SAP absorbs much less liquid in upper supernatant of AAS than in water. Mixing SAP with liquid first induces a larger absorption...
