Calibration-Free 3D Multi-Camera People Tracking for Indoor Environment

Ponleur Veng, Dominique Vaufreydaz, Phutphalla Kong

Multi-Camera People Tracking (MCPT) traditionally relies on precise intrinsic and extrinsic camera calibration to project 2D detections into a unified 3D world coordinate system.Ho…

Polyhedral Unmixing: Bridging Semantic Segmentation with Hyperspectral Unmixing via Polyhedral-Cone Partitioning

Antoine Bottenmuller, Etienne Decencière, Petr Dokládal

Semantic segmentation and hyperspectral unmixing are two central problems in spectral image analysis. The former assigns each pixel a discrete label corresponding to its material c…

''I don't want to break it'': An Exploration of Perceived Fragility in Shape-Changing Interfaces

Eva Mackamul, Tom Maillard, Noé Marceaul +6

Shape-Changing Interfaces (SCIs) dynamically alter their form, an inherent characteristic that introduces fragility into their design. As a result, users' perceptions of an interfa…
