IGen: Scalable Data Generation for Robot Learning from Open-World Images
Chenghao Gu*, Haolan Kang*, Junchao Lin*, Jinghe Wang, Duo Wu, Shuzhao Xie, Fanding Huang, Junchen Ge, Ziyang Gong, Letian Li, Hongying Zheng, Changwei Lv, Zhi Wang
IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR), 2026
project page / arXiv / pdf

IGen scalably generates realistic visual observations and executable robot actions from open-world images, enabling policies trained purely on synthesized data to match real-world data performance for robotic manipulation.

DragScene DragScene: Interactive 3D Scene Editing with Single-view Drag Instructions
Chenghao Gu, Zhenzhe Li, Zhengqi Zhang, Yunpeng Bai, Shuzhao Xie, Zhi Wang
arXiv preprint, 2024
arXiv / pdf

DragScene is an effective drag-style 3D scene editing framework, enabling controllable and view-consistent edits on real-world 3D scenes from a single reference view by combining 2D latent optimization with point-based 3D clues.

VisCtrl Tuning-Free Visual Customization via View Iterative Self-Attention Control
Xiaojie Li, Chenghao Gu, Shuzhao Xie, Yunpeng Bai, Weixiang Zhang, Zhi Wang
arXiv preprint, 2024
arXiv / pdf / code

VisCtrl is a tuning-free method that injects the appearance and structure of a user-specified subject into a target image via iterative self-attention control, enabling consistent personalized editing of images, videos, and 3D scenes with only a single reference image.
