NoCodeSeg: Deep segmentation made easy!

⚠️Latest: Generic multiclass support has been added to the pipeline!

This is the official repository for the manuscript "Code-free development and deployment of deep segmentation models for digital pathology", published open access in Frontiers in Medicine.

The repository contains trained deep models for epithelium segmentation of HE and CD3 immunostained WSIs, as well as source code relevant for importing/exporting annotations/predictions in QuPath, both from DeepMIB and FastPathology.

All relevant scripts for working with our pipeline can be found in the source directory.

See here for how to access the trained models.

See here for how to download the 251 annotated WSIs.

Getting started

.

A video tutorial of the proposed pipeline was published on YouTube. It demonstrates the steps for:

• Downloading and installing the software
• QuPath
  • Create a project, then export annotations as patches with label files
  • Export patches from unannotated images for prediction in DeepMIB
  • (later) Import predictions for MIB and FastPathology as annotations
• MIB
  • Use the annotated patches/labels exported from QuPath
  • Configuring and training deep segmentation models (i.e. U-Net/SegNet)
  • Use the trained U-Net to predict unannotated patches exported from QuPath
  • Export trained models into the ONNX format for use in FastPathology
• FastPathology
  • Importing and creating a configuration file for the DeepMIB exported ONNX model
  • Create a project and load WSIs into a project
  • Use the U-Net ONNX model to render predictions on top of the WSI in real time
  • Export full sized WSI tiffs for import into QuPath

Note that the version of FastPathology used in the demonstration was v0.2.0 (this exact version can be downloaded from here). The software is continuously in development, and features presented in the video are therefore prone to changes in the near future. To get information regarding changes and new releases, please, visit the FastPathology repository.

Data

The 251 annotated WSIs are made openly available for anyone on DataverseNO. Alternatively, the data can be downloaded directly from Google Drive (click here to access the dataset). Information on how to cite the IBDColEpi dataset can be found on DataverseNO.
