pytorch_ano_pre

Pytorch Re-implemention of ano_pre_cvpr2018, replace flownet2 with lite-flownet

Future Frame Prediction for Anomaly Detection -- A New Baseline, CVPR 2018

tensorflow_offical_implement

** This repo modify the normalization of the Regular Score, And replace flownetSD with lite-flownet ** AUC 85.6%+-0.1% of Avenue dataset

You can use FlowNet2SD Now, modify the code in train.py as the comment said.

1. requirement

• pytorch >=0.4.1
• tensorboardX (if you want)

2. preparation

1. Download Dataset CUHK Avenue download_link, unzip in the path you want, and replace the path in train.py

2. Download Lite-Flownet model, and replace the path in train.py

wget --timestamping http://content.sniklaus.com/github/pytorch-liteflownet/network-sintel.pytorch

** The quality of optical flow matters, it would be better if you finetune the liteflownet with FlyingChairsSDHom dataset**

if you want to use FlowNet2SD, you should download model form Nvidia/flownet2-pytorch, and replace the path in train.py

Flownet2SD

3. replace all the modle_output_path and log_output_path to where you want in train.py

3. training

cd ano_pre

python train.py

4. evalute

replace the model_path and evaluate_name as you want

cd ano_pre

python evaluate.py

5. reference
