Py-FEAT: Python Facial Expression Analysis Toolbox

Py-FEAT is a suite for facial expressions (FEX) research written in Python. This package includes tools to detect faces, extract emotional facial expressions (e.g., happiness, sadness, anger), facial muscle movements (e.g., action units), and facial landmarks, from videos and images of faces, as well as methods to preprocess, analyze, and visualize FEX data.

For detailed examples, tutorials, contribution guidelines, and API please refer to the Py-FEAT website.

Contributing

Note: If you forked or cloned this repo prior to 04/26/2022, you'll want to create a new fork or clone as we've used git-filter-repo to clean up large files in the history. If you prefer to keep working on that old version, you can find an archival repo here

Testing

The test have been relocated to feat/tests/. Please ensure all tests pass before creating any pull request or larger change to the code base.

Continuous Integration

Automated testing is handled by Github Actions according to the following rules:

1. On pushes to the main branch and every week on Sundays, a full test-suite will be run and docs will be built and deployed
2. On PRs against the main branch, a full test-suite will be run and docs will be built but not deployed
3. On publishing a release via github, the package will be uploaded to PyPI and docs will be built and deployed

Note: Each of these workflows can also be run manually. They can also be skipped by adding 'skip ci' anywhere inside your commit message.
