Deep Face Recognition

Introduction

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

• loss-type=0: Softmax
• loss-type=1: SphereFace
• loss-type=2: CosineFace
• loss-type=4: ArcFace
• loss-type=5: Combined Margin
• loss-type=12: TripletLoss

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:

• Refined-MS1M@BaiduDrive, Refined-MS1M@GoogleDrive
• VGGFace2@BaiduDrive, VGGFace2@GoogleDrive
• 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.

Note: If you use the refined MS1M dataset and the cropped VGG2 dataset, please cite the original papers.

Train

1. Install MXNet with GPU support (Python 2.7).

pip install mxnet-cu80

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) and place it in $INSIGHTFACE_ROOT/datasets/. Each training dataset includes following 7 files:

    faces_ms1m_112x112/
       train.idx
       train.rec
       property
       lfw.bin
       cfp_ff.bin
       cfp_fp.bin
       agedb_30.bin

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

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

export MXNET_CPU_WORKER_NTHREADS=24
export MXNET_ENGINE_TYPE=ThreadedEnginePerDevice

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_softmax.py --network r100 --loss-type 4 --margin-m 0.5 --data-dir ../datasets/faces_ms1m_112x112  --prefix ../model-r100

It will output verification results of LFW, CFP-FF, CFP-FP and AgeDB-30 every 2000 batches. You can check all command line options in train_softmax.py. This model can achieve LFW 99.80+ and MegaFace 98.0%+.

(2). Train CosineFace with LResNet50E-IR.

CUDA_VISIBLE_DEVICES='0,1,2,3' python -u train_softmax.py --network r50 --loss-type 2 --margin-m 0.35 --data-dir ../datasets/faces_ms1m_112x112 --prefix ../model-r50-amsoftmax

CUDA_VISIBLE_DEVICES='0,1,2,3' python -u train_softmax.py --network m1 --loss-type 0 --data-dir ../datasets/faces_ms1m_112x112 --prefix ../model-m1-softmax

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

CUDA_VISIBLE_DEVICES='0,1,2,3' python -u train_softmax.py --network m1 --loss-type 12 --lr 0.005 --mom 0.0 --per-batch-size 150 --data-dir ../datasets/faces_ms1m_112x112 --pretrained ../model-m1-softmax,50 --prefix ../model-m1-triplet

(6). Train MobileFaceNet network with ArcFace on MS1M dataset.

CUDA_VISIBLE_DEVICES='0,1,2,3' python -u train_softmax.py --network y1 --loss-type 4 --margin-s 128 --margin-m 0.5 --per-batch-size 128 --emb-size 128 --data-dir ../datasets/faces_ms1m_112x112 --wd 0.00004 --fc7-wd-mult 10.0 --prefix ../model-mobilefacenet-128

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=0.9, m2=0.4, m3=0.15, run following command:

CUDA_VISIBLE_DEVICES='0,1,2,3' python -u train_softmax.py --network r100 --loss-type 5 --margin-a 0.9 --margin-m 0.4 --margin-b 0.15 --data-dir ../datasets/faces_ms1m_112x112  --prefix ../model-r100

Test on MegaFace

In this part, we assume you are in the directory $INSIGHTFACE_ROOT/src/megaface/.

Note: We found there are overlap identities between facescrub dataset and Megaface distractors, which significantly affects the identification performance. This list is released under $INSIGHTFACE_ROOT/src/megaface/.

1. Align all face images of facescrub dataset and megaface distractors. Please check the alignment scripts under $INSIGHTFACE_ROOT/src/align/.
2. Generate feature files for both facescrub and megaface images.

python -u gen_megaface.py

3. Remove Megaface noises which generates new feature files.

python -u remove_noises.py

4. Run megaface development kit to produce final result.

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-r34-amf.
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).
