Détection ML
Modèle Hugging Face Transformer
Notre détection ML utilise des modèles Transformer entraînés sur des millions d'images.
Comment ça Fonctionne
Le réseau neuronal analyse les motifs visuels, textures et artefacts subtils invisibles à l'œil humain mais caractéristiques de la génération IA. Il examine les caractéristiques au niveau des pixels, les distributions de couleurs et les motifs structurels appris à partir d'images réelles et générées par IA.

Frequently Asked Questions
What is Machine Learning detection for AI images?
ML detection uses trained neural networks (specifically Vision Transformers) to analyze images and identify patterns characteristic of AI-generated content, such as those from Stable Diffusion, DALL-E, or Midjourney.
Why is ML detection weighted at 40%?
ML detection is our most accurate single method, trained on millions of images. It achieves 92-98% accuracy on direct AI outputs, making it the primary signal in our ensemble detection system.
What AI generators can ML detection identify?
Our ML model detects images from Stable Diffusion (all versions), DALL-E 2 & 3, Midjourney, Adobe Firefly, Leonardo.ai, and most diffusion-based generators.
How does the Vision Transformer work?
Vision Transformers (ViT) divide images into patches and learn attention patterns between them. They can identify subtle correlations that differ between AI-generated and real photographs.
Does image compression affect ML detection?
Moderate JPEG compression (quality 60-100) has minimal impact. Heavy compression or multiple re-compressions can reduce accuracy, which is why we use ensemble methods.
What image formats are supported?
We support JPEG, PNG, WebP, BMP, and TIFF formats. All images are preprocessed to 224x224 pixels while preserving aspect ratio for optimal model inference.
How fast is the ML detection?
Our CPU-optimized model processes images in under 500ms. GPU acceleration can reduce this to under 50ms for batch processing.
Can ML detection identify edited photos?
ML detection focuses on fully AI-generated images. For AI-enhanced or partially edited photos, other methods like clone detection work better.
Is the model updated for new AI generators?
Yes, we regularly retrain our models to include outputs from the latest AI image generators. The current model is trained on images from 2024-2026 generators.
What is the false positive rate?
Our ML model has a false positive rate under 2% for standard photographs. Heavily filtered or stylized photos may occasionally trigger false positives, which ensemble methods help mitigate.
Méthodes associées
Analyse PRNU
Photo Response Non-Uniformity (PRNU) detects unique camera sensor fingerprints from manufacturing imperfections. AI images cannot replicate these authentic sensor signatures.
Analyse Fréquentielle
L'analyse du domaine fréquentiel examine la distribution des composantes haute et basse fréquence d'une image. Les images générées par IA manquent généralement du bruit naturel haute fréquence présent dans les vraies photographies.
Analyse de gradient
Analyzes edge patterns and texture characteristics using Sobel, Canny, and Laplacian operators. AI images often have unnaturally smooth or uniform gradients.
Motif de bruit
Les vraies photographies contiennent des motifs de bruit uniques des capteurs de caméra qui varient à travers l'image. Les images générées par IA ont une distribution de bruit anormalement uniforme.
Analyse des métadonnées
Les métadonnées d'image contiennent des indices précieux sur son origine. Nous analysons les données EXIF, les signatures logicielles et autres informations intégrées pour identifier les outils de génération IA.
Empreinte GAN
Détecte les artefacts spécifiques aux GAN comme les motifs en damier et le banding couleur.
Analyse de texture
Analyse Local Binary Pattern pour les anomalies de texture dans les images IA.
Détection Anatomique
Les générateurs d'images IA créent souvent des erreurs anatomiques que les humains reconnaissent immédiatement comme fausses. Nous utilisons la vision par ordinateur pour détecter ces erreurs révélatrices.
Vérification C2PA
C2PA (Coalition for Content Provenance and Authenticity) est un standard industriel pour suivre l'origine et l'historique du contenu numérique via des signatures cryptographiques.
Semantic Inconsistency Detection
Detects logical inconsistencies like incorrect shadows, impossible perspectives, distorted reflections, and violations of physical laws that AI often produces.
Human Biometric Analysis
Uses MediaPipe to analyze human anatomy for incorrect finger counts, asymmetric eyes, unnatural skin texture, and other anatomical anomalies common in AI-generated faces.
Lighting Physics Validation
Validates light source consistency, shadow direction physics, specular highlight accuracy, and color temperature uniformity across the image.
Compression Artifact Analysis
Analyzes JPEG compression artifacts to estimate quality levels and detect re-compression patterns that indicate image manipulation or AI generation.
Edge Sharpness Analysis
Analyzes sharpness distribution across the image and validates depth-of-field consistency. AI often produces unnaturally uniform sharpness.
Statistical Pattern Analysis
Analyzes statistical properties including Shannon entropy, histogram patterns, and Benford's Law compliance to detect synthetic image characteristics.
Chromatic Aberration Analysis
Detects the absence of chromatic aberration (color fringing) that real camera lenses produce. AI images lack these optical artifacts.
Micro-Texture Analysis
Analyzes microscopic texture patterns for repetition, uniformity, and unnatural randomness that AI generators often exhibit.
Color Palette Analysis
Analyzes color distribution including saturation levels, color diversity, and white balance consistency. AI images often have oversaturated colors.
