A Blood Dataset from Camelyon 17

This dataset is a subset of the Camelyon-17 Breast Cancer Challenge. It contains 224x224 H&E histological image patches where blood has been detected. It was originally sampled to validate the blood detection capabilities of the method presented in [1]. Blood was manually identified by a trained technician.

Summary:

• 25 images from center_0 
  • 7786 tissue patches
  • 527 blood patches
  • 104 patches of other artifacts (such as blur, folded tissue, image borders, cauterized, etc. Not labeled)

The folder structure is as follows:

center/image_id/pathology_label/patch_label/

pathology_label can take the following values:

• annotated: the patch comes from a tumor annotated region (see details in Camelyon-17 Challenge)
• no_annotated: the patch comes from a non-tumor slide (negative stage label)
• unknown: the patch comes from a slide with a tumor stage label which is not annotated.

patch_label can take the following values:

• tissue: no blood or less than ~25% of blood
• blood: more than ~25% blood
• other: the patch has a significant amount (>~25%) of pixels that are nor tissue nor blood.

Patches are sampled at the maximum resolution available 40x, and the filename includes the starting pixel in the x and y dimension. For the original .tiff images at high quality, please refer to the Camelyon-17 Challenge.
