3D face recognition: from the computer security to forensics applications

3D face reconstruction algorithms are widely used in various fields, including plastic surgery and the entertainment sector, due to their numerous advantages. However, when it comes to forensic applications, the use of 3D face reconstruction must adhere to strict requirements, which currently cast doubt on its potential role in providing evidence for legal proceedings. A comprehensive investigation into the constraints, potential, and limitations of 3D face reconstruction in forensics is still lacking. The objective of this lecture is to shed light on this matter by first clarifying the relationship between forensic applications and biometrics, particularly face recognition. Subsequently, it analyzes the accomplishments of 3D face reconstruction algorithms when applied to surveillance videos and mugshot images, while addressing the existing barriers that prevent 3D face reconstruction from playing an active role in forensic applications. The lecture also includes practical laboratory exercises.
