3D Face Recognition System : Learn about the latest update in Hybrid Technique Code for 3D Face Recognition System. We present you a modern 3D face recognition approach, which is based on the geometric invariants. The key idea encompassed by the proposed algorithm is representation of the facial surface invariant to the isometric deformations i.e. the results of different facial expressions and postures. The obtained geometric invariants allow 2D mapping of facial texture images into special images, which incorporate the 3D geometry of the face. The signature images thus obtained are then broken down into their principal components. The final outcome is an efficient and accurate face recognition algorithm that is robust to facial expressions.
