Cross Quality LFW: A database for Analyzing Cross-Resolution Image Face Recognition in Unconstrained Environments

Last update: Dec 12, 2022

Overview

Cross-Quality Labeled Faces in the Wild (XQLFW)

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

Cross Quality LFW: A database for Analyzing Cross-Resolution Image Face Recognition in Unconstrained Environments

📂 Database and Evaluation Protocol

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

https://martlgap.github.io/xqlfw

💻 Code

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

🥣 Requirements

🚀 How to use

Download the database and evaluation protocol here

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, ...]]

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.
See the results and enjoy!
