Cross-Quality Labeled Faces in the Wild (XQLFW)


Here, we release the database, evaluation protocol and code for the following paper:

📂 Database and Evaluation Protocol

If you are interested in our Database and Evaluation Protocol please visit our website.

💻 Code

We provide the code to calculate the accuracy for face recognition models on the XQLFW evaluation protocol.

🥣 Requirements

Python 3.8

🚀 How to use

  1. Download the database and evaluation protocol here
  2. Inference the images and save the embeddings and labels to a numpy file (*.npy) according to:
[[pair1_img1_embed, pair1_img2_embed, pair2_img1_embed, pair2_img2_embed, ...], 
[True, True, False, ...]]
  1. Run the evaluate.py code with --source_embedding argument
    containing the absolute path to a directory containing your embedding .npy files:
python evaluate.py --source_embeddings="path/to/your/folder" --csv --save
  • Use the flag --csv if you want to get the results displayed in csv instead of a table.
  • Use the flag --save to save the results into the source_embedding directory.
  1. See the results and enjoy!
