This is my codes that can visualize the psnr image in testing videos.

This is a fantastic work in Video-level Anomaly Detection, published in CVPR2018. ShanghaiTech svip-lab has given their work in [Github]. Moreover, this work also have an interesting video in [YouTube]. And we can see that when anomaly examples happened, PSNR images will have a low response. Such is an example in avenue dataset.

After you have trained you pre-trained model, you need to make sure that you have done every step under the instruction of authors. You need to put videotest_psnr.py into Codes folder. Running the sript (as avenue datasets and video04 for examples), make sure cd into Codes folder at first.

python videotest_psnr.py --dataset avenue
                         --test_folder ../Data/avenue/testing/frames
                         --gpu 0
                         --snapshot_dir checkpoints/pretrains/avenue
                         --video_num 4

After you have run this script, just need to wait a few minutes, you can have an image just like this.

**Notes : ** I don't specify folder saving testing_psnr images in my code. But I think this is an easy work.
