The snap2dfe project is a synchronized 2D facial expression database that collects data with and without head movements. It uses a two-camera system, one fixed on a helmet and the other at near-range distance. The database provides annotations for facial landmarks and acted emotions for each frame. It also includes head orientation information from a 3-axis gyroscope. The dataset contains 93,240 annotated frames from 15 subjects.

The test-mirror project is a tool for mirroring and synchronizing data between different systems. It allows for the backup and analysis of data by creating a mirror of the original data in a separate location. The project ensures that the mirrored data is always up-to-date and consistent with the original data.

"The sync\_evaluation project is responsible for synchronizing data between different systems and automating data evaluation. It monitors data changes and ensures data consistency across various platforms."
