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.
