Introduction

This work is an extension of our previous conference paper "Beyond the Spectrum: Detecting Deepfakes via Re-synthesis" in IJCAI. In this repo, we release the code for the extension, i.e., Deepfake detection & segmentation. For the classification results, the source code is released at https://github.com/SSAW14/BeyondtheSpectrum.

Updates

• 07/03/23: Inference code and checkpoint open to public.

Setup

1. Environment

• CUDA: 11.1
• mmcv: 1.4.0
• apex: 0.1

2. Dataset

Please download OpenForensics dataset.

3. Checkpoint

Please download the checkpoint of Baseline and Ours+ (Fix SR, Pixel and Stage5) and please it in ./work_dirs/ folder.

4. Inference

We provide some samples from Openforensics in ./demo/sample/Test-Dev/ and ./demo/sample/Test-Challenge/ folders. Evaluate on single image:

python demo/image_demo.py --img <IMAGE_PATH> --config <CONFIG_FILE> --checkpoint <CHECKPOINT_FILE> --output <OUTPUT_FILE>

For example, for baseline:

python demo/image_demo.py --img demo/sample/Test-Dev/4210dfb597.jpg --config configs/swin/cascade_mask_rcnn_swin_tiny_patch4_window7_mstrain_480-800_giou_4conv1f_adamw_3x_openforensics_baseline.py  --checkpoint work_dirs/Checkpoint_Baseline.pth --output demo/sample/output/4210dfb597_baseline.jpg

For Fix SR, Pixel and Stage5:

python demo/image_demo.py --img demo/sample/Test-Dev/4210dfb597.jpg --config configs/swin/cascade_mask_rcnn_swin_tiny_patch4_window7_mstrain_480-800_giou_4conv1f_adamw_3x_openforensics.py --checkpoint work_dirs/Checkpoint_Fix_SR_Pixel_Stage5_Aug_SR_Aug.pth --output demo/sample/output/4210dfb597.jpg
