| # 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. | |
