but training data for this task is typically scarce and hard to obtain.
Here we propose DenoiSeg, a new method that can be trained end-to-end
on only a few annotated ground truth segmentations.
We achieve this by extendingNoise2Void,
a self-supervised denoising scheme that can be trained on noisy images alone,
to also predict dense 3-class segmentations. The reason for the success
of our method is that segmentation can profit from denoising, especially
when performed jointly within the same network. The network becomes a
denoising expert by seeing all available raw data, while  co-learning to
segment, even if only a few segmentation labels are available. This
hypothesis is additionally fueled by our observation that the best
segmentation results on high quality (very low noise) raw data are obtained
when moderate amounts of synthetic noise are added. This renders the
denoising-task non-trivial and unleashes the desired co-learning effect.
We believe that DenoiSeg offers a viable way to circumvent the tremendous
hunger for high quality training data and effectively enables few-shot learning
of dense segmentations.Paper:https://arxiv.org/abs/2005.02987InstallationIf you start from scratch...We recommend usingminiconda.
If you do not yet have a strong opinion, just use it too!After installing Miniconda, create a conda environment:conda create -n 'denoiseg' python=3.9
conda activate denoisegInstall TensorFlowThe best way to install TensorFLow is to follow theTensorflow guidelines.Note that, after installing TensorFlow, running the following commands in your environment will allow you to use the GPU without having to each
time run anexportcommand (refer to theTensorflow step by step):mkdir-p$CONDA_PREFIX/etc/conda/activate.decho'export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$CONDA_PREFIX/lib/'>$CONDA_PREFIX/etc/conda/activate.d/env_vars.shOption 1: PIP (current stable release)$ pip install denoisegOption 2: Git-Clone and install from sources (current master-branch version)This option is ideal if you want to edit the code. Clone the repository:$ git clone https://github.com/juglab/denoiseg.gitChange into its directory and install it:$ cd denoiseg
$ pip install -e .You are now ready to run DenoiSeg.How to use it?Have a look at our jupyter notebook:Example: DSB2018Example: Fly WingExample: Mouse NucleiHow to cite:@inproceedings{BuchholzPrakash2020DenoiSeg,
