[R] Looking for a highly accurate background sweeper tool.

I’m looking for a workflow or tool that handles object extraction and background replacement with a focus on absolute realism. I’ve experimented with standard LLMs and basic AI removers (remove.bg, etc.), but the edges and lighting never feel "baked in."

Specifically, I need:

- High Fidelity Masking: Perfect hair/edge detail without the "cut out" halo.

- Realistic Compositing: The object needs to inherit the global illumination, shadows, and color bounce of the new background.

- Forensic Integrity: The final output needs to pass machine/metadata checks for legitimacy (consistent noise patterns and ELA).

Is there a pipeline (perhaps involving ControlNet or specific Inpainting models) that achieves this level of perfection?
