Three Necessary Principles for Self-Supervised Visual Representation Learning

Nikos Giakoumoglou, Paschalis Giakoumoglou, Tania Stathaki

We argue that learning visual representations without labels requires a training signal jointly complete across three non-overlapping objectives: semantic invariance across augment…

DiffusionPrint: Learning Generative Fingerprints for Diffusion-Based Inpainting Localization

Paschalis Giakoumoglou, Symeon Papadopoulos

Modern diffusion-based inpainting models pose significant challenges for image forgery localization (IFL), as their full regeneration pipelines reconstruct the entire image via a l…

SAGI: Semantically Aligned and Uncertainty Guided AI Image Inpainting

Paschalis Giakoumoglou, Dimitrios Karageorgiou, Symeon Papadopoulos +1

Recent advancements in generative AI have made text-guided image inpainting - adding, removing, or altering image regions using textual prompts - widely accessible. However, genera…
