HOSS ReID dataset

Hybrid Optical and Synthetic Aperture Radar (SAR) Ship Re-Identification Dataset (HOSS ReID dataset) is designed to evaluate the effectiveness of ship tracking using low-Earth orbit constellations of optical and SAR sensors. This approach ensures shorter re-imaging cycles and enables all-weather tracking. HOSS ReID dataset includes images of the same ship captured over extended periods under diverse conditions, using different satellites of different modalities at varying times and angles. 2025/07/11 Update: The pretraining data has been uploaded (pretrain_data.zip, pretrain_data.z01). It is constructed based on the SEN1-2 and DFC23 datasets. Note: The complete dataset format description is provided in the readme.txt file within the compressed archive.
