+# BGM: Background Mixup for X-Ray Prohibited Items Detection
+
+[Paper](https://arxiv.org/abs/2412.00460) | [Code](https://github.com/WiZard-Leo/BackgroundMixup)
+
+Baseline and BGM-trained Mr. DETR-Align R50 checkpoints for PIDray evaluation.
+
+| Model | Positive AP | Easy AP | Hard AP | Hidden AP |
+| --- | ---: | ---: | ---: | ---: |
+| Baseline | 74.8 | 78.9 | 74.3 | 52.7 |
+| BGM | 76.8 | 80.4 | 76.3 | 56.1 |
+
+These are recorded experiment results. The separated evaluation entry point has not yet been rerun on CUDA.
+
+## Files
+
+- `output/mr_detr_align_r50_12ep/model_final.pth`: baseline.
+- `output/mr_detr_align_r50_12ep_bgm/model_final.pth`: BGM.
+- `CHECKPOINTS.json`: checkpoint sizes and SHA-256 hashes.
+
+Download the checkpoints into the matching paths in the code repository and follow its evaluation commands. Evaluation requires PIDray and a compatible Linux CUDA environment. Code repository access currently requires authorization.
+
+The release provides checkpoint evaluation, without training reproduction, multi-seed results or separate CPM/SPM ablations.
