RIGA+ Dataset for Unsupervised Domain Adaptation in Medical Image Segmentation

Different from the previous combined multi-domain dataset for unsupervised domain adaptation (UDA) in medical image segmentation, this multi-domain fundus image dataset contains annotations made by the same group of ophthalmologists. Hence the annotator bias among different datasets can be mitigated. Therefore, this dataset can provide a relatively fair benchmark for evaluating UDA methods in fundus image segmentation.

This dataset is based on the RIGA[1] dataset and MESSIDOR[2] dataset. We appreciate their efforts devoted by the authors of [1] and [2].

The six duplicated cases in the RIGA dataset are filtered out according to the Errata. We also remove the duplicated cases that exist in both the RIGA dataset and the MESSIDOR dataset by hash value matching.
