Introduction

This repository hosts the version of the code used for the publication Embedding-based Instance Segmentation of Microscopy Images.

We refer to the techniques elaborated in the publication, here as EmbedSeg. EmbedSeg is a method to perform instance-segmentation of objects in microscopy images, based on the ideas by Neven et al, 2019.

With EmbedSeg, we obtain state-of-the-art results on multiple real-world microscopy datasets. EmbedSeg has a small enough memory footprint (between 0.7 to about 3 GB) to allow network training on virtually all CUDA enabled hardware, including laptops.

Dependencies

One could execute these lines of code to run this branch with GPU support:

mamba create -n EmbedSeg python
mamba activate EmbedSeg
mamba install pytorch torchvision torchaudio pytorch-cuda=11.7 -c pytorch -c nvidia
git clone https://github.com/juglab/EmbedSeg.git
cd EmbedSeg
pip install -e .

For CPU support, one could execute the following lines of code:

mamba create -n EmbedSeg python
mamba activate EmbedSeg
pip install torch torchvision
git clone https://github.com/juglab/EmbedSeg.git
cd EmbedSeg

Getting Started

Look in the examples directory, and try out the DSB-2018 notebooks for 2D images or Mouse-Organoid-Cells-CBG notebooks for volumetric (3D) images. Please make sure to select Kernel > Change kernel to EmbedSegEnv.

Datasets

3D datasets are available as release assets here.

Training and Inference on your data

*.tif-type images and the corresponding masks should be respectively present under images and masks, under directories train, val and test. (In order to prepare such instance masks, one could use the Fiji plugin Labkit as suggested here). The following would be a desired structure as to how data should be prepared.

$data_dir
└───$project-name
    |───train
        └───images
            └───X0.tif
            └───...
            └───Xn.tif
        └───masks
            └───Y0.tif
            └───...
            └───Yn.tif
    |───val
        └───images
            └───...
        └───masks
            └───...
    |───test
        └───images
            └───...
        └───masks
            └───...
