# RefineRank: Joint Box Refinement and Ranking for Surgical Spatio-Temporal Grounding

Official checkpoints for the ECCV 2026 MedVidU Workshop paper **RefineRank**.

RefineRank couples two **frozen** backbones — a MedVLM (Qwen2.5-VL
architecture) and GroundingDINO — with a compact **1.25M-parameter** trainable
module, **RefineNet** (`QueryConditionedProposalAdapter`). RefineNet uses
MedVLM language and regional features to predict coordinate corrections and
box-quality scores for GroundingDINO proposals; a parameter-free decoder then
returns the highest-scoring original or refined box.

- **Code, training & inference guide**: https://github.com/linzhe001/RefineRank
- **Headline result**: 0.421 STG mIoU on the archived MedVidBench Community
  leaderboard snapshot (27 July 2026) — the best STG mIoU among the ten
  ranking metrics on that snapshot.
- **Controlled evaluation** (video-separated split over CholecTrack20 /
  CoPESD / EgoSurgery): STG mIoU 0.2719 → 0.4534 over the frozen
  MedVLM + GroundingDINO baseline.

## Contents

This repo hosts the complete `checkpoints/` tree expected by the code
repository — three flat folders, each holding its core files directly:

```
checkpoints/
├── vlm/                                  # frozen MedVLM, HF format (~16 GB)
│   ├── config.json, generation_config.json, tokenizer*, preprocessor_config.json, ...
│   └── model-00001..00004-of-00004.safetensors
├── grounding_dino/
│   └── groundingdino_swinb_cogcoor.pth   # frozen GroundingDINO SwinB (~895 MB)
└── refinenet/                            # trained RefineNet, this work (~5 MB)
    ├── proposal_adapter_full.pt          # SHA-256: 932e479b…463d9b
    └── deployment_manifest.json
```

- `refinenet/proposal_adapter_full.pt` is the exact checkpoint behind the
  paper's MedVidBench submission (`run_iter132_submission`). SHA-256:
  `932e479b854c3d5fbafee25a3fcf9e6481e864fe98a6867502d6ebff39463d9b`.
- `vlm/` and `grounding_dino/` are **third-party frozen weights**
  ([uAI-NEXUS-MedVLM](https://huggingface.co/UII-AI) by UII-AI and
  [GroundingDINO](https://github.com/IDEA-Research/GroundingDINO) by
  IDEA-Research), mirrored here for one-stop reproducibility. They are never
  fine-tuned by RefineRank; please follow their original licenses and cite the
  original works.

## Usage

```bash
pip install "huggingface_hub[hf_transfer]"   # hf_transfer optional, faster
hf download linzher/RefineRank --local-dir .  # restores the checkpoints/ tree

git clone https://github.com/linzhe001/RefineRank
cd RefineRank
pip install -r requirements.txt
# place the downloaded checkpoints/ next to interface.py, then:
python interface.py predict   # auto-discovers checkpoints/refinenet/
```
