This repo is the official implementation of "MOS: A Low Latency and Lightweight Framework for Face Detection, Landmark Localization, and Head Pose Estimation". The paper has been accepted at BMVC2021.

This repo is an implementation of PyTorch. MOS is a low latency and lightweight architecture for face detection, facial landmark localization and head pose estimation.It aims to bridge the gap between research and industrial communities. For more details, please refer to our report on Arxiv.

• 【2021/10/31】 We have released the training data (widerface with pose label). The pytorch inference code of MOS-S and MOS-M has been released!
• 【2021/10/22】 We have released our paper on Arxiv.
• 【2021/10/15】 "MOS: A Low Latency and Lightweight Framework for Face Detection, Landmark Localization, and Head Pose Estimation" has been accepted at BMVC2021.

• Tensorrt inference code.
• Openvino inference code.
• Ncnn inference code.
• The fastest version: MOS-tiny.

WiderFace Val Performance is in multi scale and Pose evaluation is using AFLW2000 in 300X300 as image input.

1. Generate txt file You need download the validation and test dataset of WiderFace from Here

python test_widerface.py --network cfg_mos_m --trained_model ./test_weights/MOS-M.pth

2. Evaluate txt results. Demo come from Here

cd ./widerface_evaluate
python setup.py build_ext --inplace
python evaluation.py

1. Download annotations (face bounding boxes & five facial landmarks & pose angle(pitch,yaw,roll)) from baidu cloud , the code is 0925. We also provide the GOOGLE DRIVE
2. Organise the dataset directory as follows:

  ./data/widerface/
    train/
      images/
      label.txt

The annotation file is like:

Step1. Install MOS.

git clone https://github.com/lyp-deeplearning/MOS-Multi-Task-Face-Detect.git
cd MOS-Multi-Task-Face-Detect
conda create -n MOS python=3.8.5
conda activate MOS
pip install -r requirements.txt
cd models/DCNv2/
python setup.py build develop

Step2. Run Pytorch inference demo.

## run the MOS-M model 
python detect_picture.py --network cfg_mos_m --trained_model ./test_weights/MOS-M.pth
## run the MOS-S model
python detect_picture.py --network cfg_mos_s --trained_model ./test_weights/MOS-S.pth

Step3. Run video inference demo.

## run the MOS-M model 
python detect_video.py --network cfg_mos_m --trained_model ./test_weights/MOS-M.pth
