In IEEE International Conference on Computer Vision (ICCV), 2019. [Paper][Project]

• Python 3.6
• PyTorch 0.4.1 (tested with 0.4.1)
• torchvision 0.2.1 (tested with 0.2.1)
• (optional) Tensorflow 1.3.0 (only for logging with tensorboard)
• MATLAB (for data preparation)

1. Install this repository and the required packages.
2. Download pretrained models from [MODELS]. Move them into ./models.
3. Prepare dataset.
   1. Download dataset.
   2. Move the dataset into ./dataset.
   3. The dataset folder should be organized in specific stuctures to fit the dataloader as the followings. This can be obtained by running the corresponding script in ./matlab_script.
4. Run .sh files or python script_testing.py.

1. Prepare data (as in the above 'Testing' section).
2. Run train_video_MemAE.sh file or python script_training.py. Before running the script, please set up the paths (for data, model, and results), hyperparameters, and other options defined in ./options/training_options.py.
