Gastric mucosa histopathology dataset for Helicobacter pylori infection diagnosis.

The DeepHP database comprises 394,926 histopathological images, of which ~111K were labeled as Helicobacter pylori positive and ~283K remained as Helicobacter pylori-negative. Our dataset evidenced high potential and application in the computational pathology field and contributes to emerging deep learning-based applications in precision medicine filling a gap in obtaining well-annotated data for deep learning applications.
