Curvature Distribution
Wire Frame Model
PRISM Feature Segmentation
3D Facial Recognition Uses curvature distribution, segmentation, and 3D feature extraction to provide greater accuracy and reliability than 2D pixel-based techniques. Recognizes and compares curvature in unique biometric areas that define each human face and unlike image-based techniques, is not sensitive to added make-up or facial hair.
