4DFAB: A Large Scale 4D Facial Expression Database for Biometric Applications
This database addresses the need for large-scale annotated 4D facial data for researchers in computer vision and biometrics, though it is incremental as it builds on existing data collection efforts.
The authors introduced 4DFAB, a large-scale database of dynamic high-resolution 3D faces with over 1,800,000 meshes from 180 subjects, captured over five years, to support automatic face analysis and biometric applications.
The progress we are currently witnessing in many computer vision applications, including automatic face analysis, would not be made possible without tremendous efforts in collecting and annotating large scale visual databases. To this end, we propose 4DFAB, a new large scale database of dynamic high-resolution 3D faces (over 1,800,000 3D meshes). 4DFAB contains recordings of 180 subjects captured in four different sessions spanning over a five-year period. It contains 4D videos of subjects displaying both spontaneous and posed facial behaviours. The database can be used for both face and facial expression recognition, as well as behavioural biometrics. It can also be used to learn very powerful blendshapes for parametrising facial behaviour. In this paper, we conduct several experiments and demonstrate the usefulness of the database for various applications. The database will be made publicly available for research purposes.
