🔍 Document Tampering Detection

Upload a document image to detect forged or tampered regions using Hedi model.

How it works:

• The model analyzes JPEG compression artifacts
• Red regions indicate potential tampering
• Works best on JPEG images of documents

ℹ️ About

** Document Tampering Detector** is a deep learning model designed to detect forged text in document images.

Features:

• Analyzes JPEG compression artifacts using DCT (Discrete Cosine Transform)
• Detects copy-paste, splicing, and text manipulation
• Works on scanned documents, photos of documents, and digital documents

Limitations:

• Requires JPEG images for DCT analysis
• May produce false positives on low-quality scans
• Performance varies with JPEG compression quality
