Semantic Slots for Video Object-Centric Learning
Khalil Sabri, Guillaume-Alexandre Bilodeau, Nicolas Saunier +1
Video Object-Centric Learning (OCL) has traditionally focused on refining the encoder architecture to ensure temporal consistency. In this paper, we argue that the primary bottlene…
Suicide Risk Assessment from AI-powered Video Surveillance: An Interpretable Framework for Prevention in Metro Stations
Safwen Naimi, Wassim Bouachir, Guillaume-Alexandre Bilodeau +1
Understanding and monitoring human behavior in metro stations play an important role in supporting suicide prevention efforts, where early identification of high-risk situations ca…
Dual-Stream Attention with Multi-Modal Queries for Object Detection in Transportation Applications
Noreen Anwar, Guillaume-Alexandre Bilodeau, Wassim Bouachir
Transformer-based object detectors often struggle with occlusions, fine-grained localization, and computational inefficiency caused by fixed queries and dense attention. We propose…
InceptoFormer: A Multi-Signal Neural Framework for Parkinson's Disease Severity Evaluation from Gait
Safwen Naimi, Arij Said, Wassim Bouachir +1
We present InceptoFormer, a multi-signal neural framework designed for Parkinson's Disease (PD) severity evaluation via gait dynamics analysis. Our architecture introduces a 1D ada…
SigWavNet: Learning Multiresolution Signal Wavelet Network for Speech Emotion Recognition
Alaa Nfissi, Wassim Bouachir, Nizar Bouguila +1
In the field of human-computer interaction and psychological assessment, speech emotion recognition (SER) plays an important role in deciphering emotional states from speech signal…
Detection of Micromobility Vehicles in Urban Traffic Videos
Khalil Sabri, Célia Djilali, Guillaume-Alexandre Bilodeau +2
Urban traffic environments present unique challenges for object detection, particularly with the increasing presence of micromobility vehicles like e-scooters and bikes. To address…
