Human Biometric Analysis
Finger, Eye & Skin Detection
Uses MediaPipe to analyze human anatomy for incorrect finger counts, asymmetric eyes, unnatural skin texture, and other anatomical anomalies common in AI-generated faces.
Cómo funciona
AI image generators frequently struggle with human anatomy, especially hands and faces. Using MediaPipe machine learning, this detector counts fingers, measures eye symmetry, analyzes facial proportions, and examines skin texture patterns.

Frequently Asked Questions
Why do AI images have wrong finger counts?
AI models learn hand appearance from training data without understanding that humans have exactly 5 fingers. They often generate 4, 6, or merged fingers because hands are complex and variable in photos.
How does eye symmetry detection work?
MediaPipe detects 468 facial landmarks and measures the ratio between eye sizes, positions, and angles. Real faces have natural asymmetry within specific ranges, while AI often creates unnaturally symmetric or asymmetric eyes.
Can this detect AI-generated portraits?
Yes, especially portraits with visible hands or multiple people. Even high-quality AI portraits often have subtle facial proportion errors or unnatural skin smoothness that this detector identifies.
What skin texture anomalies are detected?
The detector analyzes pore patterns, wrinkle consistency, and texture frequency. AI skin often lacks natural pore variation, has overly smooth areas, or shows repetitive texture patterns not found in real skin.
Does this work on cartoon-style images?
Biometric analysis is most effective on photorealistic images. Cartoon or stylized art intentionally deviates from human anatomy, so other detection methods are more suitable for those styles.
What facial proportions are checked?
The system measures eye-to-nose ratio, nose-to-mouth distance, face width proportions, and ear placement. AI often generates faces that look good at first glance but have proportions outside natural human ranges.
Is MediaPipe required for detection?
MediaPipe provides the best accuracy, but the system includes fallback methods using OpenCV Haar cascades when MediaPipe is unavailable. The fallback has reduced accuracy but still detects major anomalies.
How effective is this against DALL-E 3?
DALL-E 3 has significantly improved hand generation, but still makes errors in complex poses or multiple hands. The detector catches these remaining issues, though accuracy is lower than with older models.
What happens if no humans are in the image?
If no humans, hands, or faces are detected, this method returns a neutral score (0.5) and other detection methods carry more weight. The ensemble system automatically adjusts for content type.
How fast is biometric analysis?
MediaPipe is optimized for real-time processing. Full biometric analysis typically completes in 200-500ms on CPU, making it suitable for production use without significant latency.
