2. Overview


3. Training/testing

Prerequisites

  • PyTorch 1.5.0
  • Numpy 1.14.2
  • Scikit-learn 0.22.2

Datasets

We collect a large scale dataset comprising of fake images images genearted by 116 generative models. Please visit link for more details. For reverse enginnering:

  • Download the model parsing dataset and the ground truth files by following the instructions from here.
  • For leave out experiment, put the training data in train folder and leave out models data in test folder
  • For testing on custom images, put the data in test folder.

For deepfake detection:

  • Download the CelebA/LSUN dataset

For image_attribution:

Training

  • Provide the train and test path in respective codes as sepecified below.
  • Provide the model path to resume training
  • Run the code

For reverse engineering, run:

python reverse_eng.py

For deepfake detection, run:

python deepfake_detection.py

For image attribution, run:

python image_attribution.py

Testing using pre-trained models

For reverse engineering, run:

python reverse_eng_test.py

For deepfake detection, run:

python deepfake_detection_test.py

For image attribution, run:

python image_attribution_test.py
