Colorectal Adenocarcinoma Gland (CRAG) Dataset (v2)

Description: This dataset contains 213 H&E colorectal adenocarcinoma image tiles at 20x magnification with full instance-level annotation. This data was used as a dataset within the MILD-Net paper, published at Medical Image Analysis. The data is split into train and test sets, which contain 173 and 40 images respectively. If you intend to publish research work that uses this dataset, you must give appropriate citation to the MILD-Net paper. Version 2 removed the 5 extra images that were in test/Annotation/.

Data Structure:

• train /Images/ /Annotations/ /Overlay/

• test /Images/ /Annotations/ /Overlay/
