CHOW-SLAM: Compact Hybrid Representation with Complementary Overlap Window Optimization for RGB-D SLAM
Wenxuan Ji, Jin Xiao, Xiaoguang Hu +3
Simultaneous localization and mapping (SLAM) based on Neural Radiance Fields (NeRF) enables dense, continuous scene reconstruction. However, existing systems operating with limited…
Channel-Level Relation to Attentive Aggregation with Neighborhood-Homogeneity Constraint for Point Cloud Analysis
Jiaqi Shi, Jin Xiao, Xiaoguang Hu +5
In 3D point cloud understanding, the core challenge lies in accurately capturing discriminative features within complex neighborhoods, which directly affects the execution precisio…
Enhancing point cloud analysis via neighbor aggregation correction based on cross-stage structure correlation
Jiaqi Shi, Jin Xiao, Xiaoguang Hu +4
Point cloud analysis is the cornerstone of many downstream tasks, among which aggregating local structures is the basis for understanding point cloud data. While numerous works agg…
Diff-Cleanse: Identifying and Mitigating Backdoor Attacks in Diffusion Models
Jiang Hao, Xiao Jin, Hu Xiaoguang +2
Diffusion models (DMs) are regarded as one of the most advanced generative models today, yet recent studies suggest that they are vulnerable to backdoor attacks, which establish hi…
