Histology Tissue Fold Dataset with Pixel-Level Annotations for Artificial Intelligence-Based Detection and Segmentation of Tissue Fold Artifacts in H&E-Stained Teaching Slides

Description

This dataset contains 2,127 hematoxylin and eosin (H&E)-stained histological images collected from histology teaching slides representing five different tissues: brain, kidney, liver, small intestine, and testis. Images were acquired at 10× magnification.

The dataset consists of 899 clean (artifact-free) images and 1,228 images containing tissue fold artifacts. Pixel-level binary segmentation masks are provided for all 1,228 tissue fold images, enabling the dataset to be used for both image classification and semantic segmentation tasks.

Important: The slide_image_mapping.xlsx file in this version contains an earlier image-to-slide mapping. Please use Version 2 of this dataset for the corrected mapping consistent with the 302 specimens reported in the associated publication.

Slide-level image mapping

The file slide_image_mapping.xlsx provides the slide-level mapping for all images included in the dataset. Each image filename is linked to its corresponding histological slide ID, together with the tissue type and class label. This metadata allows images originating from the same histological slide to be identified and grouped consistently for slide-level data splitting and reproducible model evaluation.
