## Description

This data set represents a collection of textures in histological images of human colorectal cancer.
It contains 5000 histological images of 150 * 150 px each (74 * 74 µm). Each image belongs to exactly one of eight tissue categories.

## Image format

All images are RGB, 0.495 µm per pixel, digitized with an Aperio ScanScope (Aperio/Leica biosystems), magnification 20x.
Histological samples are fully anonymized images of formalin-fixed paraffin-embedded human colorectal adenocarcinomas (primary tumors) from our pathology archive
(Institute of Pathology, University Medical Center Mannheim, Heidelberg University, Mannheim, Germany).

## Ethics statement

All experiments were approved by the institutional ethics board (medical ethics board II, University Medical Center Mannheim, Heidelberg University, Germany; approval 2015-868R-MA).
The institutional ethics board waived the need for informed consent for this retrospective analysis of anonymized samples.
All experiments were carried out in accordance with the approved guidelines and with the Declaration of Helsinki.
