Chroma-Warp GAN: High-Capacity Reversible Image Steganography via Perceptually Guided Chrominance Modulation

Deep learning-based image steganography enables secure covert communication by hiding information within images imperceptibly. Although recent GAN-based methods with hybrid attention improve stego image quality and secret recovery, they operate in RGB space, modifying all channels and causing visible distortions. Since...
