!!2022年结合MobileOne的性能更加优异的人脸关键点检测算法已开源->PFLD_GhostOne
- PFLD的训练/测试/评估/ncnn C++推理
- PFLD_Ulitralight的训练/测试/评估/ncnn C++推理
- 人脸98个关键点检测
- 支持onnx导出
提供了一系列适合移动端部署的人脸关键点检测器： 对PFLD网络的基础结构进行优化，并调整网络结构，使其更适合边缘计算，而且在绝大部分情况下精度均好于原始PFLD网络，在CPU下运行最快可达到400fps。
- Ubuntu 16.04
- Python 3.7
- Pytorch 1.4
- CUDA 10.1
如果想省去环境搭建工作，可以使用以下Docker环境: Docker_PFLD

Clone and install:
- git clone https://github.com/AnthonyF333/PFLD_UltraLight.git
- cd ./PFLD_UltraLight
- pip install -r requirement.txt
- Pytorch version 1.4.0 are needed.
- Codes are based on Python 3.7
Data:
- Download WFLW dataset:
- Move the WFLW.zip to ./data/ directory and unzip the WFLW.zip
- Run SetPreparation.py to generate the training and test data.
- By default, it repeats 10 times for every image for augmentation, and save results in ./data/test_data/ and ./data/train_data/ directory.
Before training, check or modify network configuration (e.g. batch_size, epoch and steps etc..) in config.py.
- MODEL_TYPE: you can choose PFLD, PFLD_Ultralight or PFLD_Ultralight_Slim for different network.
- WIDTH_FACTOR: you can choose 1 for original network or 0.25 for narrower network.
- TRAIN_DATA_PATH: the path of training data, by default it is ./data/train_data/list.txt which is generate by SetPreparation.py.
- VAL_DATA_PATH: the path of validation data, by default it is ./data/test_data/list.txt which is generate by SetPreparation.py.
After modify the configuration, run train.py to start training.
Before test, modify the configuration in test.py, include the model_path, test_dataset, model_type, width_factor etc. Then run test.py to align the images in the test dataset, and save results in ./test_result directory.
- Generate the onnx file: Modify the model_type, width_factor, model_path in pytorch2onnx.py, and then run pytorch2onnx.py to generate the xxx.onnx file.
- Simplify the onnx file: First run "pip3 install onnx-simplifier" to install the tool, then run "python3 -m onnxsim xxx.onnx xxx_sim.onnx" to simpify the onnx file.
- Transform onnx to ncnn format: Run "./onnx2ncnn xxx_sim.onnx xxx_sim.param xxx_sim.bin" to generate the ncnn files.
