Analyzing large complex image collections in domains like forensics, accident investigation, or social media analysis involves interpreting intricate, overlapping relationships amo…
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…
Scraping the Shadows: Deep Learning Breakthroughs in Dark Web Intelligence
Ingmar Bakermans, Daniel De Pascale, Gonçalo Marcelino +2
Darknet markets (DNMs) facilitate the trade of illegal goods on a global scale. Gathering data on DNMs is critical to ensuring law enforcement agencies can effectively combat crime…
