Installation

Docker

(1) Pull a docker image from docker hub:

docker pull pytorch/pytorch:1.13.1-cuda11.6-cudnn8-runtime

(2) Replace the absolute path to this repository in ./exec.sh.
(3) Execute the image:

bash exec.sh

Pretrained Models

We provide trained models for ArcFace and BlendFace and place them to checkpoints/.

Demo

We provide a demo code to compute identity similarities of ArcFace and BlendFace for an actual positive pair (images/anchor.png and images/positive.png), negative pair (images/anchor.png and images/negative.png), and pseudo-positive pair (images/anchor.png and images/swapped.png).

python3 demo.py

The result will be displayed as follows:

> ArcFace| Positive: 0.7967, Negative: 0.0316, Swapped: 0.6212
> BlendFace| Positive: 0.8186, Negative: -0.0497, Swapped: 0.8015

It can be seen that ArcFace underestimates the similarity for the pseudo-positive pair while BlendFace predicts properly it, which indicates BlendFace mitigates the biases while keeping the discriminativeness for the negative sample.

Face-Swapping

We also provide code for face-swapping (AEI-Net + BlendFace). The pretrained checkpoint is here.
Move to /workspace/swapping.

cd /workspace/swapping

Swap target face with source face:

python3 inference.py \
    -w checkpoints/blendswap.pth \ # path to checkpoint
    -s examples/source.png \ # path to source image
    -t examples/target.png \ # path to target image
    -o examples/output.png # path to output image

Note: source images should be aligned following InsightFace and target images should be aligned following FFHQ.

Training BlendFace

Please see training/README.md.
