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.

Getting started

  1. Clone the repository:

     git clone https://github.com/ydwen/opensphere.git
    
  2. Setup the environment:

     cd opensphere
     conda env create -f environment.yml
    
  3. Download the dataset:

     bash scripts/dataset_setup.sh
    
  4. Train the SphereFace2 model:

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

    or train the SphereFace model:

     CUDA_VISIBLE_DEVICES=0,1 python train.py --config config/train/vggface2_sfnet20_sphereface.yml
    
  5. Test the model:

     CUDA_VISIBLE_DEVICES=0,1 python test.py --config config/test/ijbb.yml
    

See our Github page for detailed instructions.
