Suhyeon presented “APT: Anchor-aligned Perturbations for Tamper Localization in Fully Regenerated Images“
APT introduces a semi-fragile latent-space perturbation for localizing image manipulations when diffusion inpainting regenerates the entire image rather than only the edited region. It aligns spatial feature vectors to a fixed anchor and detects tampering from the resulting alignment disparity, maintaining accurate localization under fully regenerated inpainting where prior proactive methods degrade substantially.
