NeuS-PIR: Learning Relightable Neural Surface using Pre-Integrated Rendering

1 code implementation13 Jun 2023 Shi Mao, Chenming Wu, Zhelun Shen, Yifan Wang, Dayan Wu, Liangjun Zhang

This paper presents a method, namely NeuS-PIR, for recovering relightable neural surfaces using pre-integrated rendering from multi-view images or video.


AREA: Adaptive Reweighting via Effective Area for Long-Tailed Classification

1 code implementation ICCV 2023 Xiaohua Chen, Yucan Zhou, Dayan Wu, Chule Yang, Bo Li, QinGhua Hu, Weiping Wang

Consequently, we estimate the size of the spanned space for each category, namely effective area, by detailedly analyzing its samples' distribution.

Handling Label Uncertainty for Camera Incremental Person Re-Identification

no code implementations17 Oct 2022 Zexian Yang, Dayan Wu, Wanqian Zhang, Bo Li, Weiping Wang

Specifically, new data collected from new cameras may probably contain an unknown proportion of identities seen before.

Imagine by Reasoning: A Reasoning-Based Implicit Semantic Data Augmentation for Long-Tailed Classification

1 code implementation15 Dec 2021 Xiaohua Chen, Yucan Zhou, Dayan Wu, Wanqian Zhang, Yu Zhou, Bo Li, Weiping Wang

Since the covariance matrix of each category represents the feature transformation directions, we can sample new directions from similar categories to generate definitely different instances.

Mask is All You Need: Rethinking Mask R-CNN for Dense and Arbitrary-Shaped Scene Text Detection

no code implementations8 Sep 2021 Xugong Qin, Yu Zhou, Youhui Guo, Dayan Wu, Zhihong Tian, Ning Jiang, Hongbin Wang, Weiping Wang

We propose to use an MLP decoder instead of the "deconv-conv" decoder in the mask head, which alleviates the issue and promotes robustness significantly.
