HumanRecon: Neural Reconstruction of Dynamic Human Using Geometric Cues and Physical Priors

1 code implementation26 Nov 2023 Junhui Yin, Wei Yin, Hao Chen, Xuqian Ren, Zhanyu Ma, Jun Guo, Yifan Liu

These priors ensure the color rendered along rays to be robust to view direction and reduce the inherent ambiguities of density estimated along rays.
