Raw Imagery Impacting Your AI: Should You Care?
Adrien Dorise, Marjorie Bellizzi, Stéphane May
Onboard AI is gaining interest for space applications such as vessel, wildfire, and cloud detection, where real-time processing can improve mission reactivity and reduce downlink n…
Enhancing Photogrammetric Digital Surface Models with Pretrained Diffusion Models and Multimodal Conditioning
Antoine Lorentz, Stéphane May, Valentine Bellet +2
Large-scale Digital Surface Models (DSMs) can be produced cost-effectively from satellite images via stereo-photogrammetry. However, the resulting 3D maps are often contaminated by…
TriCCOT: Tri-part Convolutional Conformal Transformer for Onboard Space Object Detection
Adrien Dorise, Marjorie Bellizzi, Julia Cohen +1
Onboard object detection in Earth observation is constrained by limited computational resources and the absence of fully corrected imagery. While convolutional detectors are hardwa…
EoS-FM: Can an Ensemble of Specialist Models act as a Generalist Feature Extractor?
