Download the Anomaly Detection Dataset and convert it to MVTec AD format. (The convert script.)
The dataset folder structure should look like:
DATA_PATH/
subset_1/
train/
good/
test/
good/
defect_class_1/
defect_class_2/
defect_class_3/
...
...
Step 2. Generate Training/Test Json Files of Datasets.(The generate script.)
The json folder structure should look like:
JSON_PATH/
dataset_1/
subset_1/
subset_1_train_normal.json
subset_1_train_outlier.json
subset_1_val_normal.json
subset_1_val_outlier.json
subset_2/
subset_3/
...
...
Step 3. Download the Few-shot Normal Samples for Inference on Google Drive
Step 4. Download the Pre-train Models on Google Drive
Change the TEST.CHECKPOINT_FILE_PATH
in config to the path of pre-train model. and run
python test.py --val_normal_json_path $normal-json-files-for-testing --val_outlier_json_path $abnormal-json-files-for-testing --category $dataset-class-name --few_shot_dir $path-to-few-shot-samples
For example, if run on the category candle
of visa
with k=2
:
python test.py --val_normal_json_path /AD_json/visa/candle_val_normal.json --val_outlier_json_path /AD_json/visa/candle_val_outlier.json --category candle --few_shot_dir /fs_samples/visa/2/
python main.py --normal_json_path $normal-json-files-for-training --outlier_json_path $abnormal-json-files-for-training --val_normal_json_path $normal-json-files-for-testing --val_outlier_json_path $abnormal-json-files-for-testing
WinCLIP is one main competing method to ours, but its official implentation is not publicly available. We have successfully reproduced the results of WinCLIP based on our extensive communications with its authors and used our implementation to perform experiments in the paper. Our implementation has been released at WinCLIP.
