Neural Rays for Occlusion-aware Image-based Rendering

no code implementations28 Jul 2021 YuAn Liu, Sida Peng, Lingjie Liu, Qianqian Wang, Peng Wang, Christian Theobalt, Xiaowei Zhou, Wenping Wang

Experiments demonstrate that NeuRay can quickly generate high-quality novel view images of unseen scenes with little finetuning and can handle complex scenes with severe self-occlusions which previous methods struggle with.

Animatable Neural Radiance Fields for Modeling Dynamic Human Bodies

1 code implementation ICCV 2021 Sida Peng, Junting Dong, Qianqian Wang, Shangzhan Zhang, Qing Shuai, Xiaowei Zhou, Hujun Bao

Moreover, the learned blend weight fields can be combined with input skeletal motions to generate new deformation fields to animate the human model.

Neural Body: Implicit Neural Representations with Structured Latent Codes for Novel View Synthesis of Dynamic Humans

2 code implementations CVPR 2021 Sida Peng, Yuanqing Zhang, Yinghao Xu, Qianqian Wang, Qing Shuai, Hujun Bao, Xiaowei Zhou

To this end, we propose Neural Body, a new human body representation which assumes that the learned neural representations at different frames share the same set of latent codes anchored to a deformable mesh, so that the observations across frames can be naturally integrated.

Doubly Robust Semiparametric Difference-in-Differences Estimators with High-Dimensional Data

no code implementations7 Sep 2020 Yang Ning, Sida Peng, Jing Tao

This paper proposes a doubly robust two-stage semiparametric difference-in-difference estimator for estimating heterogeneous treatment effects with high-dimensional data.

Deep Snake for Real-Time Instance Segmentation

1 code implementation CVPR 2020 Sida Peng, Wen Jiang, Huaijin Pi, Xiuli Li, Hujun Bao, Xiaowei Zhou

Based on deep snake, we develop a two-stage pipeline for instance segmentation: initial contour proposal and contour deformation, which can handle errors in object localization.

GIFT: Learning Transformation-Invariant Dense Visual Descriptors via Group CNNs

1 code implementation NeurIPS 2019 Yuan Liu, Zehong Shen, Zhixuan Lin, Sida Peng, Hujun Bao, Xiaowei Zhou

Instead of feature pooling, we use group convolutions to exploit underlying structures of the extracted features on the group, resulting in descriptors that are both discriminative and provably invariant to the group of transformations.

PVNet: Pixel-wise Voting Network for 6DoF Pose Estimation

1 code implementation CVPR 2019 Sida Peng, Yu-An Liu, Qi-Xing Huang, Hujun Bao, Xiaowei Zhou

We further create a Truncation LINEMOD dataset to validate the robustness of our approach against truncation.

Robust Estimation of Causal Effects via High-Dimensional Covariate Balancing Propensity Score

no code implementations20 Dec 2018 Yang Ning, Sida Peng, Kosuke Imai

We first use a class of penalized M-estimators for the propensity score and outcome models.
