PanNuke

Pan-Cancer H&E Nuclei Instance Segmentation and Classification dataset (Gamper et al., ECDP 2019; arXiv:2003.10778). Mirrored from the Warwick TIA Centre release.

Composition

—7,901 RGB patches of 256x256 at 40x magnification (~0.25 um/pixel)
—19 tissue types pooled from TCGA / GTEx (Breast, Colon, Lung, Kidney, Prostate, Stomach, Ovarian, Bladder, Esophagus, Pancreatic, Thyroid, Skin, Cervix, Adrenal_gland, Bile-duct, Liver, HeadNeck, Testis, Uterus)
—~189,744 annotated nuclei, multi-pathologist QC
—3 folds (PanNuke is designed for 3-fold cross-validation):
—fold1: 2,656 patches
—fold2: 2,523 patches
—fold3: 2,722 patches

Schema

Field	Type	Description
`image`	PIL RGB 256x256	H&E patch, uint8
`inst_map`	PIL grayscale uint16 256x256	Global per-pixel instance ID (0 = background)
`type_map`	PIL grayscale uint8 256x256	Semantic class per pixel (see table below)
`tissue`	int	Tissue ID 0-18 (alphabetical)
`tissue_name`	str	Tissue type name
`fold`	int	Source fold (1, 2, or 3)
`sample_id`	str	Unique ID, `foldN_NNNN`

Semantic class encoding (`type_map`)

Value	Class
0	Background
1	Neoplastic
2	Inflammatory
3	Connective / Soft tissue
4	Dead
5	Epithelial

Instance map (`inst_map`)

Each connected nucleus is assigned a unique 16-bit integer ID per patch (starting from 1). IDs are derived from the original 6-channel mask arrays released by Warwick: for each foreground class channel, instance IDs are offset by the running count of nuclei in previous channels so the result is globally unique within the patch.
