Datasets

To train on the MVtec Anomaly Detection dataset download the data and extract it. The Describable Textures dataset was used as the anomaly source image set in most of the experiments in the paper. You can run the download_dataset.sh script from the project directory to download the MVTec and the DTD datasets to the datasets folder in the project directory:

./scripts/download_dataset.sh

Training

Pass the folder containing the training dataset to the train_DRAEM.py script as the --data_path argument and the folder locating the anomaly source images as the --anomaly_source_path argument. The training script also requires the batch size (--bs), learning rate (--lr), epochs (--epochs), path to store checkpoints (--checkpoint_path) and path to store logs (--log_path). Example:

python train_DRAEM.py --gpu_id 0 --obj_id -1 --lr 0.0001 --bs 8 --epochs 700 --data_path ./datasets/mvtec/ --anomaly_source_path ./datasets/dtd/images/ --checkpoint_path ./checkpoints/ --log_path ./logs/

The conda environement used in the project is decsribed in requirements.txt.

Pretrained models

Pretrained DRAEM models for each class of the MVTec anomaly detection dataset are available here. To download the pretrained models directly see ./scripts/download_pretrained.sh.

The pretrained models achieve a 98.1 image-level ROC AUC, 97.5 pixel-wise ROC AUC and a 68.9 pixel-wise AP.

Evaluating

The test script requires the --gpu_id arguments, the name of the checkpoint files (--base_model_name) for trained models, the location of the MVTec anomaly detection dataset (--data_path) and the folder where the checkpoint files are located (--checkpoint_path) with pretrained models can be run with:

python test_DRAEM.py --gpu_id 0 --base_model_name "DRAEM_seg_large_ae_large_0.0001_800_bs8" --data_path ./datasets/mvtec/ --checkpoint_path ./checkpoints/DRAEM_checkpoints/
