Classification of bacterial biological warfare agent simulants through 2D Py-GC/MS data coupled with deep learning

Georgios Kirtsanis, Alejandra Vargas-Valderrama, Joeri Vercammen, Georgios Dolias, Spyridon Kintzios, Konstantinos Ioannidis, et al.

Identification and detection of biological warfare agents (BWAs) constitute a critical task for both biodefence applications and public health protection. Gas Chromatography coupled with Mass Spectrometry (GC/MS) represents a robust analytical platform due to its sensitivity to V…Read more

Learning Perceptual Hash Similarity for Image Copy Detection

Maria Pegia, Dimitrios Stefanopoulos, Björn Þór Jónsson, Anastasia Moumtzidou, Ilias Gialampoukidis, Stefanos Vrochidis, et al.

Image copy detection is commonly addressed using either local descriptors or deep learning models, which can be computationally expensive and rely on high-dimensional features. In contrast, this work explores copy detection using compact perceptual hash representations and learne…Read more
