🛰️ FLAIR #2
<img src="assets/flair-2.png">The challenge involves a semantic segmentation task focusing on land cover description using multimodal remote sensing earth observation data. Participants will explore heterogeneous data fusion methods in a real-world scenario. Upon registration, access is granted to a dataset containing 70,000+ aerial imagery patches with pixel-based annotations and 50,000 Sentinel-2 satellite acquisitions.
This project was made possible by our compute partners 2CRSi and NVIDIA.
