DRAN: Detailed Region-Adaptive Normalization for Conditional Image Synthesis [article]

Yueming Lyu, Peibin Chen, Jingna Sun, Xu Wang, Jing Dong, Tieniu Tan
2021 arXiv   pre-print
Although recent works have achieved realistic results, most of them fail to handle fine-grained styles with subtle details.  ...  To address this problem, a novel normalization module, named DRAN, is proposed.

Detailed 2D-3D Joint Representation for Human-Object Interaction [article]

Yong-Lu Li, Xinpeng Liu, Han Lu, Shiyi Wang, Junqi Liu, Jiefeng Li, Cewu Lu
2020 arXiv   pre-print
First, we utilize the single-view human body capture method to obtain detailed 3D body, face and hand shapes.  ...  However, rough 3D body joints just carry sparse body information and are not sufficient to understand complex interactions. Thus, we need detailed 3D body shape to go further.  ...  These information would largely help the HOI learning, especially on actions related to face and hands. jects. Thus we need holistic and fine-grained 3D body information as a clue.  ...
