Decorative Image: Text Box: Curvature Distribution Decorative Image: Text Box: Wire Frame Model Decorative Image: Text Box: PRISM Feature Segmentation Decorative Image: Text Box: 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. Is less sensitive to added make-up or facial hair than 2D image-based techniques.
