A revisit of sparse coding based anomaly detection in stacked rnn framework

This repo is the official open source of [A revisit of sparse coding based anomaly detection in stacked rnn framework, ICCV 2017]

It is implemented on tensorflow. Please follow the instructions to run the code.

1. Installation (Anaconda with python3.6 installation is recommended)

• Install 3rd-package dependencies of python (listed in requirements.txt)

numpy==1.15.4
matplotlib==2.2.2
scikit_image==0.13.1
six==1.11.0
opencv_python==3.4.3.18
h5py==2.7.1
scipy==1.1.0
tensorflow_gpu==1.11.0
seaborn==0.8.1
skimage==0.0
scikit_learn==0.20.2
tensorflow==1.12.0
PyYAML==3.13

pip install -r requirements.txt

pip install tensorflow-gpu==1.11.0

2. Download datasets

cd into Data folder of project and run the shell scripts (ped1.sh, ped2.sh, avenue.sh, shanghaitech.sh) under the Data folder.

cd dataset/anomaly_detection

Please manually download all datasets ped2.tar.gz, avenue.tar.gz and shanghaitech.tar.gz and tar -xv each tar.gz file. Folders will be like dataset/anomaly_detection/avenue/....

3. Extracting feature

cd extract_feature
git clone https://github.com/feichtenhofer/twostreamfusion.git

Please infer the instructions of the twostreamfusion model and download pretrained models.

cd extract_feature/extract_feature_twostream

Modidy the root/dataset/res_type/gpu_id in extract_feature.m

run extract_feature.m using MATLAB

4. Training

For the ICCV version:

python run_anomaly_detection.py config/anomaly_detection.yaml 0

For the TPAMI version:

python run_anomaly_detection_coherence.py config/anomaly_detection_coherence.yaml 0

5. Testing

For the ICCV version:

python run_anomaly_detection.py config/anomaly_detection.yaml 1

For the TPAMI version:

python run_anomaly_detection_coherence.py config/anomaly_detection_coherence.yaml 1

6. Evaluation

After running the testing scripts, you also need to run the evaluation.py to calculate AUC

python evaluate.py --file=results/ad_coherence/info_avenue_\* --type=compute_auc
