Deep Face Recognition

Introduction

In this module, we provide training data, network settings and loss designs for deep face recognition. The training data includes, but not limited to the cleaned MS1M, VGG2 and CASIA-Webface datasets, which were already packed in MXNet binary format. The network backbones include ResNet, MobilefaceNet, MobileNet, InceptionResNet_v2, DenseNet, etc.. The loss functions include Softmax, SphereFace, CosineFace, ArcFace, Sub-Center ArcFace and Triplet (Euclidean/Angular) Loss.

You can check the detail page of our work ArcFace(which accepted in CVPR-2019) and SubCenter-ArcFace(which accepted in ECCV-2020).

Our method, ArcFace, was initially described in an arXiv technical report. By using this module, you can simply achieve LFW 99.83%+ and Megaface 98%+ by a single model. This module can help researcher/engineer to develop deep face recognition algorithms quickly by only two steps: download the binary dataset and run the training script.

Training Data

All face images are aligned by ficial five landmarks and cropped to 112x112:

Please check Dataset-Zoo for detail information and dataset downloading.

• Please check recognition/tools/face2rec2.py on how to build a binary face dataset. You can either choose MTCNN or RetinaFace to align the faces.

Train

1. Install MXNet with GPU support (Python 3.X).

pip install mxnet-cu101 # which should match your installed cuda version

2. Clone the InsightFace repository. We call the directory insightface as INSIGHTFACE_ROOT.

git clone --recursive https://github.com/deepinsight/insightface.git

3. Download the training set (MS1M-Arcface) and place it in $INSIGHTFACE_ROOT/recognition/datasets/. Each training dataset includes at least following 6 files:

    faces_emore/
       train.idx
       train.rec
       property
       lfw.bin
       cfp_fp.bin
       agedb_30.bin

The first three files are the training dataset while the last three files are verification sets.

4. Train deep face recognition models. In this part, we assume you are in the directory $INSIGHTFACE_ROOT/recognition/ArcFace/.

Place and edit config file:

cp sample_config.py config.py
vim config.py # edit dataset path etc..

We give some examples below. Our experiments were conducted on the Tesla P40 GPU.

(1). Train ArcFace with LResNet100E-IR.

CUDA_VISIBLE_DEVICES='0,1,2,3' python -u train.py --network r100 --loss arcface --dataset emore

It will output verification results of LFW, CFP-FP and AgeDB-30 every 2000 batches. You can check all options in config.py. This model can achieve LFW 99.83+ and MegaFace 98.3%+.

(2). Train CosineFace with LResNet50E-IR.

CUDA_VISIBLE_DEVICES='0,1,2,3' python -u train.py --network r50 --loss cosface --dataset emore

(3). Train Softmax with LMobileNet-GAP.

CUDA_VISIBLE_DEVICES='0,1,2,3' python -u train.py --network m1 --loss softmax --dataset emore

(4). Fine-turn the above Softmax model with Triplet loss.

CUDA_VISIBLE_DEVICES='0,1,2,3' python -u train.py --network m1 --loss triplet --lr 0.005 --pretrained ./models/m1-softmax-emore,1

(5). Training in model parallel acceleration.

CUDA_VISIBLE_DEVICES='0,1,2,3' python -u train_parall.py --network r100 --loss arcface --dataset emore

5. Verification results.

LResNet100E-IR network trained on MS1M-Arcface dataset with ArcFace loss:

Pretrained Models

You can use $INSIGHTFACE_ROOT/recognition/arcface_torch/eval/verification.py to test all the pre-trained models.

Please check Model-Zoo for more pretrained models.

Verification Results on Combined Margin

A combined margin method was proposed as a function of target logits value and original θ:

COM(θ) = cos(m_1*θ+m_2) - m_3

For training with m1=1.0, m2=0.3, m3=0.2, run following command:

CUDA_VISIBLE_DEVICES='0,1,2,3' python -u train.py --network r100 --loss combined --dataset emore

Results by using MS1M-IBUG(MS1M-V1)

Test on MegaFace

Please check $INSIGHTFACE_ROOT/evaluation/megaface/ to evaluate the model accuracy on Megaface. All aligned images were already provided.

512-D Feature Embedding

In this part, we assume you are in the directory $INSIGHTFACE_ROOT/deploy/. The input face image should be generally centre cropped. We use RNet+ONet of MTCNN to further align the image before sending it to the feature embedding network.

1. Prepare a pre-trained model.
2. Put the model under $INSIGHTFACE_ROOT/models/. For example, $INSIGHTFACE_ROOT/models/model-r100-ii.
3. Run the test script $INSIGHTFACE_ROOT/deploy/test.py.

For single cropped face image(112x112), total inference time is only 17ms on our testing server(Intel E5-2660 @ 2.00GHz, Tesla M40, LResNet34E-IR).

Face Detection

RetinaFace

RetinaFace is a practical single-stage SOTA face detector which is initially introduced in arXiv technical report and then accepted by CVPR 2020. We provide training code, training dataset, pretrained models and evaluation scripts.

Please check RetinaFace for detail.

RetinaFaceAntiCov

RetinaFaceAntiCov is an experimental module to identify face boxes with masks. Please check RetinaFaceAntiCov for detail.

Face Alignment

DenseUNet

Please check the Menpo Benchmark and our Dense U-Net for detail. We also provide other network settings such as classic hourglass. You can find all of training code, training dataset and evaluation scripts there.

CoordinateReg

On the other hand, in contrast to heatmap based approaches, we provide some lightweight facial landmark models with fast coordinate regression. The input of these models is loose cropped face image while the output is the direct landmark coordinates. See detail at alignment-coordinateReg. Now only pretrained models available.
