Robustness of AI Image Compression: Non-linear Perturbation
摘要
Modern AI-based image compression methods significantly outperform traditional techniques. However, they remain vulnerable to adversarial attacks designed either to degrade the quality of reconstruction by injecting imperceptible noise into the original image. In this work, we further investigate this issue and propose using the Tanh-Arctanh function to generate perturbed images, which allows noise to be applied in a non-linear manner relative to pixel brightness. We demonstrate the effectiveness of this approach against those targeting maximal distortion on the Kodak dataset showing significant improvements in PSNR and SSIM compared to traditional methods.
