LiDAR-based 4D Occupancy Completion and Forecasting

1 code implementation17 Oct 2023 Xinhao Liu, Moonjun Gong, Qi Fang, Haoyu Xie, Yiming Li, Hang Zhao, Chen Feng

In this paper, we introduce a novel LiDAR perception task of Occupancy Completion and Forecasting (OCF) in the context of autonomous driving to unify these aspects into a cohesive framework.

Autonomous Driving Hallucination

Among Us: Adversarially Robust Collaborative Perception by Consensus

1 code implementation ICCV 2023 Yiming Li, Qi Fang, Jiamu Bai, Siheng Chen, Felix Juefei-Xu, Chen Feng

This leads to our hypothesize-and-verify framework: perception results with and without collaboration from a random subset of teammates are compared until reaching a consensus.

Learning Analytical Posterior Probability for Human Mesh Recovery

1 code implementation CVPR 2023 Qi Fang, Kang Chen, Yinghui Fan, Qing Shuai, Jiefeng Li, Weidong Zhang

Despite various probabilistic methods for modeling the uncertainty and ambiguity in human mesh recovery, their overall precision is limited because existing formulations for joint rotations are either not constrained to SO(3) or difficult to learn for neural networks.

iVS-Net: Learning Human View Synthesis from Internet Videos

no code implementations ICCV 2023 Junting Dong, Qi Fang, Tianshuo Yang, Qing Shuai, Chengyu Qiao, Sida Peng

However, these methods usually rely on limited multi-view images typically collected in the studio or commercial high-quality 3D scans for training, which heavily prohibits their generalization capability for in-the-wild images.

Reconstructing 3D Human Pose by Watching Humans in the Mirror

1 code implementation CVPR 2021 Qi Fang, Qing Shuai, Junting Dong, Hujun Bao, Xiaowei Zhou

In this paper, we introduce the new task of reconstructing 3D human pose from a single image in which we can see the person and the person's image through a mirror.

3D Pose Estimation

SMAP: Single-Shot Multi-Person Absolute 3D Pose Estimation

1 code implementation ECCV 2020 Jianan Zhen, Qi Fang, Jiaming Sun, Wentao Liu, Wei Jiang, Hujun Bao, Xiaowei Zhou

Recovering multi-person 3D poses with absolute scales from a single RGB image is a challenging problem due to the inherent depth and scale ambiguity from a single view.
