InterOCF: Spatio-Temporal 2D-3D Interaction for Camera-Only 4D Occupancy Forecasting
Qi Zhang, Xinquan Yu, Kaiyi Zhang +1
Camera-only 4D occupancy forecasting enables autonomous vehicles to predict future 3D semantic scenes solely from historical multi-view images, which is critical for driving safety…
Multiview Multi-Person Human Mesh Recovery Under Large Scenes with Occlusions
Qi Zhang, Tao Yu, Jiechao He +2
Human mesh recovery (HMR) aims to recover 3D human meshes from images. Most existing HMR benchmarks and methods focus on either multi-person reconstruction from a single view or si…
Multi-view Crowd Tracking Transformer with View-Ground Interactions Under Large Real-World Scenes
Qi Zhang, Jixuan Chen, Kaiyi Zhang +3
Multi-view crowd tracking estimates each person's tracking trajectories on the ground of the scene. Recent research works mainly rely on CNNs-based multi-view crowd tracking archit…
SynMVCrowd: A Large Synthetic Benchmark for Multi-view Crowd Counting and Localization
Qi Zhang, Daijie Chen, Yunfei Gong +1
Existing multi-view crowd counting and localization methods are evaluated under relatively small scenes with limited crowd numbers, camera views, and frames. This makes the evaluat…
EnvSocial-Diff: A Diffusion-Based Crowd Simulation Model with Environmental Conditioning and Individual-Group Interaction
Bingxue Zhao, Qi Zhang, Hui Huang
Modeling realistic pedestrian trajectories requires accounting for both social interactions and environmental context, yet most existing approaches largely emphasize social dynamic…
Semi-Supervised Multi-View Crowd Counting by Ranking Multi-View Fusion Models
Qi Zhang, Yunfei Gong, Zhidan Xie +3
Multi-view crowd counting has been proposed to deal with the severe occlusion issue of crowd counting in large and wide scenes. However, due to the difficulty of collecting and ann…
