Deep Face Recognition


In this repository, we provide training data, network settings and loss designs for deep face recognition. The training data includes the normalised MS1M, VGG2 and CASIA-Webface datasets, which were already packed in MXNet binary format. The network backbones include ResNet, MobilefaceNet, MobileNet, InceptionResNet_v2, DenseNet, DPN. The loss functions include Softmax, SphereFace, CosineFace, ArcFace and Triplet (Euclidean/Angular) Loss.

margin penalty for target logit

Our method, ArcFace, was initially described in an arXiv technical report. By using this repository, you can simply achieve LFW 99.80%+ and Megaface 98%+ by a single model. This repository 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 MTCNN and cropped to 112x112:

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

  • Please check src/data/face2rec2.py on how to build a binary face dataset. Any public available MTCNN can be used to align the faces, and the performance should not change. We will improve the face normalisation step by full pose alignment methods recently.


  1. Install MXNet with GPU support (Python 2.7).
pip install mxnet-cu90
  1. Clone the InsightFace repository. We call the directory insightface as INSIGHTFACE_ROOT.
git clone --recursive https://github.com/deepinsight/insightface.git
  1. Download the training set (MS1M-Arcface) and place it in $INSIGHTFACE_ROOT/datasets/. Each training dataset includes at least following 6 files:

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

  1. Train deep face recognition models. In this part, we assume you are in the directory $INSIGHTFACE_ROOT/recognition/.
export MXNET_ENGINE_TYPE=ThreadedEnginePerDevice

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 99.80+ 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
  1. Verification results.

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

Method LFW(%) CFP-FP(%) AgeDB-30(%)
Ours 99.80+ 98.0+ 98.20+

Pretrained Models

You can use $INSIGHTFACE/src/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_softmax.py --network r100 --loss combined --dataset emore

Results by using MS1M-IBUG(MS1M-V1)

Method m1 m2 m3 LFW CFP-FP AgeDB-30
W&F Norm Softmax 1 0 0 99.28 88.50 95.13
SphereFace 1.5 0 0 99.76 94.17 97.30
CosineFace 1 0 0.35 99.80 94.4 97.91
ArcFace 1 0.5 0 99.83 94.04 98.08
Combined Margin 1.2 0.4 0 99.80 94.08 98.05
Combined Margin 1.1 0 0.35 99.81 94.50 98.08
Combined Margin 1 0.3 0.2 99.83 94.51 98.13
Combined Margin 0.9 0.4 0.15 99.83 94.20 98.16

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).
