Requirements

Usage

Testing

  1. Install this repository and the required packages.
  2. Download pretrained models from [MODELS]. Move them into ./memae_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 (To be added).
  4. Run .sh files or python script_testing.py.

Training

Training code will be released later. (To be added)
