📄 HOComp: Interaction-Aware Human-Object Composition
📚 Preprint available on arXiv

HOComp is a novel framework for harmonizing foreground objects into human-centric backgrounds.
By leveraging a Flux.1 Kontext base model and a novel Sequence Concatenation strategy, the method achieves precise control over human–object interactions with high fidelity.

To generate a specific interaction, provide background / foreground images, the interaction prompt, and the foreground bounding box:

python run_inference.py \
  --prompt "A young man holding a vintage camera" \
  --bg_path "examples/background.jpg" \
  --fg_path "examples/camera.png" \
  --box "[300 300 700 700]"
