AnySat: One Earth Observation Model for Many Resolutions, Scales, and Modalities

CVPR 2025highlight

Geospatial models must adapt to the diversity of Earth observation data in terms of resolutions, scales, and modalities. However, existing approaches expect fixed input configurations, which limits their practical applicability. We propose AnySat, a multimodal model based on joint embedding predicti…

The Change You Want To Detect: Semantic Change Detection In Earth Observation With Hybrid Data Generationf

CVPR 2025poster

Bi-temporal change detection at scale based on Very High Resolution (VHR) images is crucial for Earth monitoring. Such task remains poorly addressed even in the deep learning era: it either requires large volumes of annotated data - in the semantic case - or is limited to restricted datasets for bin…

OmniSat: Self-Supervised Modality Fusion for Earth Observation

ECCV 2024poster

"The diversity and complementarity of sensors available for Earth Observations (EO) calls for developing bespoke self-supervised multimodal learning approaches. However, current multimodal EO datasets and models typically focus on a single data type, either mono-date images or time series, which lim…

StegoGAN: Leveraging Steganography for Non-Bijective Image-to-Image Translation

CVPR 2024poster

Most image-to-image translation models postulate that a unique correspondence exists between the semantic classes of the source and target domains. However this assumption does not always hold in real-world scenarios due to divergent distributions different class sets and asymmetrical information re…

FLAIR : a Country-Scale Land Cover Semantic Segmentation Dataset From Multi-Source Optical Imagery

NeurIPS 2023poster

We introduce the French Land cover from Aerospace ImageRy (FLAIR), an extensive dataset from the French National Institute of Geographical and Forest Information (IGN) that provides a unique and rich resource for large-scale geospatial analysis. FLAIR contains high-resolution aerial imagery with a g…
