OpenSphere is a hyperspherical face recognition library based on PyTorch. Check out the project homepage.

 

Introduction

OpenSphere provides a consistent and unified training and evaluation framework for hyperspherical face recognition research. The framework decouples the loss function from the other varying components such as network architecture, optimizer, and data augmentation. It can fairly compare different loss functions in hyperspherical face recognition on popular benchmarks, serving as a transparent platform to reproduce published results.

Supported Projects

Update

  • 2022.4.28: added SphereFace-R, Glint360K, and more pretrained models.
  • 2022.4.22: added SphereFace+, MS1M, and config files on MS1M.
  • 2022.4.12: added SFNet (with BN) and IResNet.
  • 2022.4.9: added the download script for some datasets.
  • 2022.4.1: initial commit.

Key Features

Setup

  1. Clone the OpenSphere repository. We'll call the directory that you cloned OpenSphere as $OPENSPHERE_ROOT.

    git clone https://github.com/ydwen/opensphere.git

  2. Construct virtual environment in Anaconda:

    conda env create -f environment.yml

Get started

In this part, we assume you are in the directory $OPENSPHERE_ROOT. After successfully completing the Setup, you are ready to run all the following experiments.

  1. Download and process the datasets

  • Download the training set (VGGFace2), validation set (LFW, Age-DB, CA-LFW, CP-LFW), and test set (IJB-B and IJB-C) and place them in data/train, data/val amd data/test, respectively.

  • For convenience, we provide a script to automatically download the data. Simply run

    bash scripts/dataset_setup.sh

  • If you need the MS1M training set, please run the additional commend:

    bash scripts/dataset_setup_ms1m.sh

  • To download other datasets (e.g., WebFace or Glint360K), see the scripts folder and find what you need.

  1. Train a model (see the training config file for the detailed setup)

    We give a few examples for training on different datasets with different backbone architectures:

  • To train SphereFace2 with SFNet-20 on VGGFace2, run the following commend (with 2 GPUs):

    CUDA_VISIBLE_DEVICES=0,1 python train.py --config config/train/vggface2_sfnet20_sphereface2.yml

  • To train SphereFace with SFNet-20 on VGGFace2, run the following commend (with 2 GPUs):

    CUDA_VISIBLE_DEVICES=0,1 python train.py --config config/train/vggface2_sfnet20_sphereface.yml

  • To train SphereFace-R (v2,HFN) with SFNet-20 on VGGFace2, run the following commend (with 2 GPUs):

    CUDA_VISIBLE_DEVICES=0,1 python train.py --config config/train/vggface2_sfnet20_spherefacer.yml

  • To train SphereFace with SFNet-64 (with BN) on MS1M, run the following commend (with 4 GPUs):

    CUDA_VISIBLE_DEVICES=0,1,2,3 python train.py --config config/train/ms1m_sfnet64bn_sphereface.yml

  • To train SphereFace with IResNet-100 on MS1M, run the following commend (with 4 GPUs):

    CUDA_VISIBLE_DEVICES=0,1,2,3 python train.py --config config/train/ms1m_iresnet100_sphereface.yml

  • We provide many config files for training, see this folder for details.

  • After finishing training a model, you will see a project folder under $OPENSPHERE_ROOT. The trained model is saved in the folder named by the job starting time, eg, 20220422_031705 for 03:17:05 on 2022-04-22.

  • Our framework also re-implements some other popular hyperspherical face recognition methods such as ArcFace, AM-Softmax (CosFace) and CocoLoss (NormFace). Please check out the folder model/head and some examplar config files in the folder config/papers/SphereFace2/sec31.

  1. Test a model (see the testing config file for detailed setup)

  • To test on the combined validation dataset, simply run

    CUDA_VISIBLE_DEVICES=0,1 python test.py --config config/test/combined.yml --proj_dir project/##YourFolder##

  • To test on both IJB-B and IJB-C, simply run

    CUDA_VISIBLE_DEVICES=0,1 python test.py --config config/test/ijb.yml --proj_dir project/##YourFolder##

  • To test on IJB-B, simply run

    CUDA_VISIBLE_DEVICES=0,1 python test.py --config config/test/ijbb.yml --proj_dir project/##YourFolder##

  • To test on IJB-C, simply run

    CUDA_VISIBLE_DEVICES=0,1 python test.py --config config/test/ijbc.yml --proj_dir project/##YourFolder##

For more information about how to use training and testing config files, please see here.

Reproduce published results

We create an additional folder config/papers that is used to provide detailed config files and reproduce results in published papers. Currently we provide config files for the following papers:

  • SphereFace2: Binary Classification is All You Need for Deep Face Recognition, ICLR 2022
