Defeats both cryptographic (SHA-256) and perceptual hash (dHash) duplicate detection systems. Should pass most image duplicate checking software tests.
Real-time similarity analysis shows effectiveness

Supports JPG, PNG, WebP, and other image formats
🎯 Mimics Dolhansky's & Ferrer's approach: Iterative gradient descent with L2 regularization produces imperceptible smooth perturbations that defeat perceptual hashing.
