Face related toolkit. This repo is still under construction to include more models.
- [14/05/2023] Face attribute recognition model trained on CelebA is available, check it out here.
- [04/05/2023] Face alignment model trained on IBUG300W, AFLW19, WFLW dataset is available, check it out here.
- [27/04/2023] Face parsing model trained on CelebM dataset is available, check it out here.
The easiest way to install it is using pip:
pip install git+https://github.com/FacePerceiver/facer.git@mainNo extra setup needs, pretrained weights will be downloaded automatically.
If you have trouble install from source, you can try install from PyPI:
pip install pyfacerthe PyPI version is not guaranteed to be the latest version, but we will try to keep it up to date.
We simply wrap a retinaface detector for easy usage.
import facer
image = facer.hwc2bchw(facer.read_hwc('data/twogirls.jpg')).to(device=device) # image: 1 x 3 x h x w
face_detector = facer.face_detector('retinaface/mobilenet', device=device)
with torch.inference_mode():
faces = face_detector(image)
facer.show_bchw(facer.draw_bchw(image, faces))
