FUSED: Forensic-Semantic Mixture-of-Experts for AI Inpainting Detection and Localization
Anton Nuzhdin, Marcel Worring, Ivona Najdenkoska
Diffusion-based inpainting models modify only a localized part of an image, while many AI-image detectors rely on global artifacts and do not localize. These artifacts vary across…
InfoCIR: Multimedia Analysis for Composed Image Retrieval
Ioannis Dravilas, Ioannis Kapetangeorgis, Anastasios Latsoudis +3
Composed Image Retrieval (CIR) allows users to search for images by combining a reference image with a text prompt that describes desired modifications. While vision-language model…
Forensic Activity Classification Using Digital Traces from iPhones: A Machine Learning-based Approach
Conor McCarthy, Jan Peter van Zandwijk, Marcel Worring +1
Smartphones and smartwatches are ever-present in daily life, and provide a rich source of information on their users' behaviour. In particular, digital traces derived from the phon…
Hi-OSCAR: Hierarchical Open-set Classifier for Human Activity Recognition
Conor McCarthy, Loes Quirijnen, Jan Peter van Zandwijk +2
Within Human Activity Recognition (HAR), there is an insurmountable gap between the range of activities performed in life and those that can be captured in an annotated sensor data…
LATTE: Latent Trajectory Embedding for Diffusion-Generated Image Detection
Ana Vasilcoiu, Ivona Najdenkoska, Zeno Geradts +1
The rapid advancement of diffusion-based image generators has made it increasingly difficult to distinguish generated from real images. This erodes trust in digital media, making i…
