Street Gaussians for Modeling Dynamic Urban Scenes

no code implementations2 Jan 2024 Yunzhi Yan, Haotong Lin, Chenxu Zhou, Weijie Wang, Haiyang Sun, Kun Zhan, Xianpeng Lang, Xiaowei Zhou, Sida Peng

We introduce Street Gaussians, a new explicit scene representation that tackles all these limitations.

Zero-Shot Point Cloud Registration

no code implementations5 Dec 2023 Weijie Wang, Guofeng Mei, Bin Ren, Xiaoshui Huang, Fabio Poiesi, Luc van Gool, Nicu Sebe, Bruno Lepri

The cornerstone of ZeroReg is the novel transfer of image features from keypoints to the point cloud, enriched by aggregating information from 3D geometric neighborhoods.

Turn Fake into Real: Adversarial Head Turn Attacks Against Deepfake Detection

no code implementations3 Sep 2023 Weijie Wang, Zhengyu Zhao, Nicu Sebe, Bruno Lepri

Although effective deepfake detectors have been proposed, they are substantially vulnerable to adversarial attacks.

Point Cloud Completion Guided by Prior Knowledge via Causal Inference

no code implementations28 May 2023 Songxue Gao, Chuanqi Jiao, Ruidong Chen, Weijie Wang, Weizhi Nie

In this paper, we propose a novel approach to point cloud completion task called Point-PC, which uses a memory network to retrieve shape priors and designs a causal inference model to filter missing shape information as supplemental geometric information to aid point cloud completion.

T2TD: Text-3D Generation Model based on Prior Knowledge Guidance

no code implementations25 May 2023 Weizhi Nie, Ruidong Chen, Weijie Wang, Bruno Lepri, Nicu Sebe

Meanwhile, to effectively integrate multi-modal prior knowledge into textual information, we adopt a novel multi-layer transformer structure to progressively fuse related shape and textual information, which can effectively compensate for the lack of structural information in the text and enhance the final performance of the 3D generation model.

RFR-WWANet: Weighted Window Attention-Based Recovery Feature Resolution Network for Unsupervised Image Registration

1 code implementation7 May 2023 Mingrui Ma, Tao Wang, Lei Song, Weijie Wang, Guixia Liu

Furthermore, shifted window partitioning operations are inflexible, indicating that they cannot perceive the semantic information over uncertain distances and automatically bridge the global connections between windows.

Dynamically Instance-Guided Adaptation: A Backward-Free Approach for Test-Time Domain Adaptive Semantic Segmentation

1 code implementation CVPR 2023 Wei Wang, Zhun Zhong, Weijie Wang, Xi Chen, Charles Ling, Boyu Wang, Nicu Sebe

In this paper, we study the application of Test-time domain adaptation in semantic segmentation (TTDA-Seg) where both efficiency and effectiveness are crucial.

Rethinking the Learning Paradigm for Facial Expression Recognition

no code implementations30 Sep 2022 Weijie Wang, Nicu Sebe, Bruno Lepri

Due to the subjective crowdsourcing annotations and the inherent inter-class similarity of facial expressions, the real-world Facial Expression Recognition (FER) datasets usually exhibit ambiguous annotation.
