Domain-RAG is a novel retrieval-augmented generative framework designed for Cross-Domain Few-Shot Object Detection (CD-FSOD). We leverage large-scale vision-language models (GroundingDINO), a curated COCO-style retrieval corpus, and Flux-based background generation to synthesize diverse, domain-aware training data that enhances FSOD generalization under domain shift.

---

✨ Highlights

• 🔍 Retrieval-Augmented Generation: retrieve semantically similar source images for novel-class prompts.
• 🎨 Flux-Redux Integration: compose diverse backgrounds with target foregrounds for domain-aligned generation.
• 📦 Support for Multiple Target Domains: ArTAXOr, Clipart1k, DIOR, DeepFish, UODD, NEU-DET, and more.
• 🧪 Strong Benchmarks: surpasses GroundingDINO baseline in 1-shot and 5-shot CD-FSOD across 6 datasets.
