Spoof Detection TRIZ Cases
- Disguised Face Recognition via Gabor Features and SVM
A facial recognition system extracts Gabor features using an SVM classifier to identify disguised faces.
- 2D 3D Object Dimension Identification via Multi-Focal Resolution Analysis
A photo shooting unit captures images at different focal lengths to determine object dimensions through resolution comparison.
- Image Injection Detection via Hue-Saturation Correlation
A verification module maps image frames to hue-saturation color space and generates distribution histograms for analysis.
- Document Fraud Detection via Landmark Noise Modeling
Transformed landmark locations combined with noise models generate synthetic training data that reduces false rejections of genuine documents.
- Scenario-Adaptive Neural Network for Living Body Detection
Segmented scenario classification and local quality adaptation improve measurement precision in living body detection despite poor photography effects.
- Display Device Identity via Reflection Pattern Extraction
A system projects illumination through a display to extract reflection patterns for device identity determination.
- Face Database Search for Fraud Detection
A face database search system extracts feature vectors from query images to identify candidate identities.
- Polarized Infrared Face Detection via Orthogonal Image Analysis
A polarized infrared face detection system captures parallel and orthogonal images to extract specular texture characteristics for verification.
- Tamper Detection Using Edge Weight and Intensity Metrics
A tamper detection system calculates edge weights and intensity changes to identify unauthorized camera adjustments.
- Live Facial Recognition via Structured Light Projection
A live facial recognition system projects structured light patterns onto subjects to capture reflected distortions for accurate liveness detection.
