Pytorch Face Landmark Detection
February 25, 2021 · View on GitHub
Implementation of face landmark detection with PyTorch. The models were trained using coordinate-based or heatmap-based regression methods. Different face detetors were supported. A video demo and image detection results were displayed here.
- Support 68-point and 39-point landmark inference.
- Support automatic alignment and crop
- Support different backbone networks and face detectors.
- Support ONNX and OpenVINO inferences.
- Support heatmap-based models.
Inference
Test on a sample folder and save the landmark detection and cropped face results. Support different backbones and face detectors.
python3 test_batch_detections.py --backbone MobileFaceNet --detector Retinaface
- backbone: MobileNet/PFLD/MobileFaceNet; detector: MTCNN/FaceBoxes/Retinaface
Optimize with ONNX and test on a camera with MTCNN as a face detector.
python3 test_camera_mtcnn_onnx.py
Optimize with ONNX and test on a camera with a lightweight face detector. It can achieve real-time speed on CPU.
python3 test_camera_light_onnx.py
Optimize with OpenVINO and test on a camera with a lightweight face detector. About 10 times faster than ONNX.
python3 test_camera_mobilefacenet_openvino.py
