Gluon FR Toolkit

GluonFR is a toolkit based on MXnet-Gluon, provides SOTA deep learning algorithm and models in face recognition.

Installation

GluonFR supports Python 3.5 or later. To install this package you need install GluonCV and MXNet first:

pip install gluoncv --pre
pip install mxnet-mkl --pre --upgrade
# if cuda XX is installed
pip install mxnet-cuXXmkl --pre --upgrade

Then install gluonfr:

• From Source(recommend)

pip install git+https://github.com/THUFutureLab/gluon-face.git@master

• Pip

pip install gluonfr

GluonFR Introduction:

GluonFR is based on MXnet-Gluon, if you are new to it, please check out dmlc 60-minute crash course.

Data:

This part provides input pipeline for training and validation, all datasets is aligned by mtcnn and cropped to (112, 112) by DeepInsight, they converted images to train.rec, train.idx and val_data.bin files, please check out [insightface/Dataset-Zoo] for more information. In data/dali_utils.py, there is a simple example of Nvidia-DALI. It is worth trying when data augmentation with cpu can not satisfy the speed of gpu training,

The files should be prepared like:

face/
    emore/
        train.rec
        train.idx
        property
    ms1m/
        train.rec
        train.idx
        property
    lfw.bin
    agedb_30.bin
    ...
    vgg2_fp.bin

We use ~/.mxnet/datasets as default dataset root to match mxnet setting.

Loss:

GluonFR provides implement of losses in recent, including SoftmaxCrossEntropyLoss, ArcLoss, TripletLoss, RingLoss, CosLoss, L2Softmax, ASoftmax, CenterLoss, ContrastiveLoss, ... , and we will keep updating in future.
If there is any method we overlooked, please open an issue.

Example:

examples/ shows how to use gluonfr to train a face recognition model, and how to get Mnist 2-D feature embedding visualization.

Losses in GluonFR:

The last column of this chart is the best LFW accuracy reported in paper, they are trained with different data and networks, later we will give our results of these method with same train data and network.

Method	Paper	Visualization of MNIST	LFW
Contrastive Loss	ContrastiveLoss	-	-
Triplet	1503.03832	-	99.63±0.09
Center Loss	CenterLoss		99.28
L2-Softmax	1703.09507	-	99.33
A-Softmax	1704.08063	-	99.42
CosLoss/AMSoftmax	1801.05599/1801.05599		99.17
Arcloss	1801.07698		99.82
Ring loss	1803.00130		99.52
LGM Loss	1803.02988		99.20±0.03
