This is the codebase for the NeurIPS 2020 paper "Restoring Negative Information in Few-Shot Object Detection". The code will be continuously improved. For any questions/issues, please open an issue in this repository or email me at [email protected].

The codebase is modified on the basis of RepMet (https://github.com/jshtok/RepMet). It is built based on Python 2.7, MXNet 1.5.1, and CUDA 10.0.130. Other packages include matplotlib, opencv-python, PyYAML, etc. You may need to change some file paths to run the code.

Please download the data and pre-trained model from https://cloud.tsinghua.edu.cn/f/461fd3c8ca4f46fbbc80/?dl=1 and put it in the root directory.

To reconstruct the 1-shot, 5-way experiment with the NP-RepMet from the NeurIPS paper, run
python fpn/few_shot_benchmark_1_shot.py --test_name=RepMet_inloc --Nshot=1 --Nway=5 --Nquery_cat=10 --Nepisodes=500

To reconstruct the 5-shot, 5-way experiment with the NP-RepMet from the NeurIPS paper, run
python fpn/few_shot_benchmark_5_shot.py --test_name=RepMet_inloc --Nshot=5 --Nway=5 --Nquery_cat=10 --Nepisodes=500

To train the model from scratch, run
python ./experiments/fpn_end2end_train_test.py --cfg=./experiments/cfgs/resnet_v1_101_voc0712_trainval_fpn_dcn_oneshot_end2end_ohem_8.yaml
