For Fake's Sake: a set of models for detecting generated and synthetic images

Many people on the internet have recently been tricked by fake images of Pope Francis wearing a coat or of Donald Trump's arrest. To help combat this issue, we provide detectors for such images generated by popular tools like Midjourney and Stable Diffusion.

How to Get Started with the Model & Model Sources

Use the code below to get started with the model:

git lfs install
git clone https://huggingface.co/Sumsub/Sumsub-ffs-synthetic-2.0 sumsub-ffs-synthetic-v2

from sumsub-ffs-synthetic-v2.pipeline import PreTrainedPipeline
from PIL import Image

pipe = PreTrainedPipeline("sumsub-ffs-synthetic-v2/")

img = Image.open("sumsub-ffs-synthetic-v2/images/2.jpg")

result = pipe(img)
print(result)

You may need these prerequsites installed:

pip install -r requirements.txt
pip install "git+https://github.com/rwightman/pytorch-image-models"
pip install "git+https://github.com/huggingface/huggingface_hub"

Training Details

Training Data

The models were trained on the following datasets:

Training Procedure

To improve the performance metrics, we used data augmentations such as rotation, crop, Mixup and CutMix. Each model was trained for 30 epochs using early stopping with batch size equal to 32.

Evaluation

For evaluation we used the following datasets:

AI photos:
