Wavelet-based GAN Fingerprint Detection using ResNet50

arXiv — cs.CVTuesday, October 28, 2025 at 4:00:00 AM
A new research paper introduces an innovative wavelet-based method for detecting images generated by Generative Adversarial Networks (GANs), which is crucial for digital image forensics. By utilizing discrete wavelet transform (DWT) preprocessing alongside a ResNet50 classification layer, this approach effectively distinguishes between StyleGAN-generated images and real ones. This advancement is significant as it addresses the growing challenge of identifying synthetic images, which has implications for authenticity in various fields, including media and security.
