To solve this ill-posed problem, we propose novel techniques to better model the geometry and shadow changes.

Physical Interaction: Reconstructing Hand-object Interactions with Physics

1 code implementation22 Sep 2022 Haoyu Hu, Xinyu Yi, Hao Zhang, Jun-Hai Yong, Feng Xu

Single view-based reconstruction of hand-object interaction is challenging due to the severe observation missing caused by occlusions.

OcclusionFusion: Occlusion-aware Motion Estimation for Real-time Dynamic 3D Reconstruction

1 code implementation CVPR 2022 Wenbin Lin, Chengwei Zheng, Jun-Hai Yong, Feng Xu

In our technique, the motion of visible regions is first estimated and combined with temporal information to infer the motion of the occluded regions through an LSTM-involved graph neural network.

Finding Optimal Tangent Points for Reducing Distortions of Hard-label Attacks

1 code implementation NeurIPS 2021 Chen Ma, Xiangyu Guo, Li Chen, Jun-Hai Yong, Yisen Wang

In this paper, we propose a novel geometric-based approach called Tangent Attack (TA), which identifies an optimal tangent point of a virtual hemisphere located on the decision boundary to reduce the distortion of the attack.

Simulating Unknown Target Models for Query-Efficient Black-box Attacks

1 code implementation CVPR 2021 Chen Ma, Li Chen, Jun-Hai Yong

The meta-gradients of this loss are then computed and accumulated from multiple tasks to update the Simulator and subsequently improve generalization.
