Fig. 3: Pathology and tissue substructure segmentation of GTEx histology samples.

A H&E WSI of tibial artery, esophagus mucosa and colonic tissue. B Segmentation of substructures and localised pathological features via k-Nearest neighbours on tile features. WSI tissue types have been labelled according to their GTEx descriptor which may not perfectly represent the specimen (e.g. the esophagus mucosa example includes submucosa).
