Proposed utilizing Transformer to model the spatio-temporal relationship between human posture and clothing movement
locally and globally, considering that humans wearing loose clothing were difficult to model by NeRF (Neural Radiance
Fields) under the guidance of the SMPL (Skinned Multi-Person Linear) model.
Generated more realistic dynamic details of clothing and handled the movement of clothing (e.g., open jackets), compared
to methods that rely heavily on the nude body template topology. Enhanced training efficiency by 40% through the
implementation of Distributed Data Parallel (DDP) for multi-GPU training,
Developed a professional Web https://github.com/MatrixBrain/awesome-NeRF and gave back to the research area by
cataloguing NeRF’s papers, which was highly recommended by other researchers.
