Solutions for Object Masking
DragAnything uses a hierarchical inference mechanism to deal with the occlusion problem, with specific coping strategies:
Technical realization principle
- Depth perception module: Automatic estimation of scene depth map (z-buffer)
- Dynamic Masking System: Real-time updating of the silhouette of the obscured object through the SAM model.
- Motion Prioritization Algorithm: Automatically adjusts the object hierarchy according to the degree of trajectory intersection
Operational solutions
- Manual intervention mode::
- Enable the "occlusion_handling" option in the Gradio interface.
- Mark the occlusion relationship with the brush tool (red → yellow → green priority)
- Automated Processes::
- Set -occlusion_threshold 0.7 before running (default)
- Add the -force_visible parameter to keyframes.
- Subsequent Compensation Program::
- Repairing interrupt trajectories with inpaint_trajectory.py
- Frame-by-frame fine-tuning via Blender
Special Scenario Suggestion: For translucent objects (e.g. glass), you need to set the material properties separately in data_spec.yaml.
