Occlusion-Robust Multimodal Emotion Recognition in VR via Fusion of Facial Images and EMG
Birgit Nierula, Karam Tomotaki-Dawoud, Mert Akguel +5
Head-mounted displays (HMDs) fundamentally limit emotion recognition in virtual reality (VR): by occluding the upper face, they render conventional image-based facial expression an…
Temporal Preservation over Processing: Diagnosing and Designing Spatiotemporal Single-Stage Video Detectors
Karam Tomotaki-Dawoud, Anna Hilsmann, Peter Eisert +1
Single-stage video object detectors are increasingly deployed in time-critical applications, yet it remains unclear whether these models genuinely reason over temporal context or m…
From Multimodal Signals to Adaptive XR Experiences for De-escalation Training
Birgit Nierula, Karam Tomotaki-Dawoud, Daniel Johannes Meyer +4
We present the early-stage design and implementation of a multimodal, real-time communication analysis system intended as a foundational interaction layer for adaptive VR training.…
The Impact of Federated Learning on Distributed Remote Sensing Archives
Anand Umashankar, Karam Tomotaki-Dawoud, Nicolai Schneider
Remote sensing archives are inherently distributed: Earth observation missions such as Sentinel-1, Sentinel-2, and Sentinel-3 have collectively accumulated more than 5 petabytes of…
Event-Level Detection of Surgical Instrument Handovers in Videos with Interpretable Vision Models
Katerina Katsarou, George Zountsas, Karam Tomotaki-Dawoud +6
Reliable monitoring of surgical instrument exchanges is essential for maintaining procedural efficiency and patient safety in the operating room. Automatic detection of instrument…
