MorphoDeep

MorphoDeep is a Python package for performing membrane instance segmentation using a pre-trained U-Net model based on the Semantic format.
It produces a dense labels image where each unique integer corresponds to a segmented cell instance. It also includes a napari plugin

The plugin is designed for:

• fluorescence images of cell membranes
• 2D and 3D volumes (with optional isotropic rescaling)
• interactive use in napari or scripted use in Python

---

Key features

• Pre-trained U-Net for 2D / pseudo-3D membrane instance segmentation
• Napari widget with:
  • image layer selection
  • network patch size (128 or 256)
  • 2D / 3D mode
  • optional tiling (“patches mode”) for large images
  • voxel size and Z-axis selection
  • optional isotropic rescaling for anisotropic volumes
  • Automatic model download and caching on first use

Installation

Setup your environnement

conda create -y -n morphodeep-env python=3.10
conda activate morphodeep-env

You can install morphodeep via ffpip:

pip install morphodeep

Installation with napari

Setup your environnement

conda create -y -n napari-env -c conda-forge python=3.11
conda activate napari-env

You can install morphodeep plugin with napari and Qt via:

pip install "napari[all]"
pip install "morphodeep[napari]"

MorphoDeep library Usage

You have 3 way to use the morphodeep library:

1. with a command line : python morphodeep.py <args>
2. directly inside the python code using the semantic library: MorphoModel(args)
3. directly in napari with the morphodeep plugin
