"Humor, Art, or Misinformation?": A Multimodal Dataset for Intent-Aware Synthetic Image Detection
Anastasios Skoularikis, Stefanos-Iordanis Papadopoulos, Symeon Papadopoulos +1
Recent advances in multimodal AI have enabled progress in detecting synthetic and out-of-context content. However, existing efforts largely overlook the intent behind AI-generated…
Improving Generalization in Deepfake Detection with Face Foundation Models and Metric Learning
Stelios Mylonas, Symeon Papadopoulos
The increasing realism and accessibility of deepfakes have raised critical concerns about media authenticity and information integrity. Despite recent advances, deepfake detection…
Composite Data Augmentations for Synthetic Image Detection Against Real-World Perturbations
Efthymia Amarantidou, Christos Koutlis, Symeon Papadopoulos +1
The advent of accessible Generative AI tools enables anyone to create and spread synthetic images on social media, often with the intention to mislead, thus posing a significant th…
HAL-NeRF: High Accuracy Localization Leveraging Neural Radiance Fields
Asterios Reppas, Grigorios-Aris Cheimariotis, Panos K. Papadopoulos +2
Precise camera localization is a critical task in XR applications and robotics. Using only the camera captures as input to a system is an inexpensive option that enables localizati…
P-TAME: Explain Any Image Classifier with Trained Perturbations
Mariano V. Ntrougkas, Vasileios Mezaris, Ioannis Patras
The adoption of Deep Neural Networks (DNNs) in critical fields where predictions need to be accompanied by justifications is hindered by their inherent black-box nature. In this pa…
FaceX: Understanding Face Attribute Classifiers through Summary Model Explanations
Ioannis Sarridis, Christos Koutlis, Symeon Papadopoulos +1
EXplainable Artificial Intelligence (XAI) approaches are widely applied for identifying fairness issues in Artificial Intelligence (AI) systems. However, in the context of facial a…
