NTIRE2025_CDFSOD Small-shot Object Detection Dataset

This dataset is used by the first cross-domain small sample object detection challenge NTIRE 2025, which includes the source dataset COCO and multiple verification datasets such as ArTaxOr, Clipart1k, DIOR, DeepFish, NEU-DET, UODD, etc.

The competition was initiated by researchers Fu Yuqian, Wang Yu, Pan Yixuan and others at the CVPR conference in 2025. The core research problem of this dataset is how to perform target detection in cross-domain scenarios using only very limited annotated target images.
