🛠️ How It Works

The Technology Behind The Magic

DeepDetect V2 combines cutting-edge AI technologies to provide reliable deepfake detection:

┌─────────────────────────────────────────────────────────────────┐
│  Your Upload  →  Face Detection  →  MesoNet Model  →  Gemini AI │
│   (Image/Video)     (MTCNN)      (Deep Learning)   (Explanation) │
└─────────────────────────────────────────────────────────────────┘

🧠 The Detection Process

1. Face Extraction - MTCNN technology locates and extracts the primary face from your media
2. Microscopic Analysis - MesoNet deep learning model examines pixel-level inconsistencies invisible to the human eye
3. Confidence Scoring - The model assigns a confidence score (0-100%) indicating likelihood of manipulation
4. AI Explanation - Google's Gemini AI analyzes the visual evidence and explains the verdict in plain English
