Official Gradio demo for ObjCtrl-2.5D: Training-free Object Control with Camera Poses.
🔥 ObjCtrl2.5D enables object motion control in a I2V generated video via transforming 2D trajectories to 3D using depth, subsequently converting them into camera poses,
thereby leveraging the exisitng camera motion control module for object motion control without requiring additional training.
