A classification plugin for the ROIs of a segmentation mask.
Project description
# napari_svetlana
The aim of this plugin is to classify the output of a segmentation algorithm. The inputs are :
- A folder of raw images
- Their segmentation masks where each ROI has its own label.
Svetlana can process 2D, 3D and multichannel image. If you want to use it to work on cell images, we strongly recommend the use of Cellpose for the segmentation part, as it provides excellent quality results and a standard output format accepted by Svetlana (labels masks).
If you use this plugin please cite the paper:

This napari plugin was generated with Cookiecutter using @napari's cookiecutter-napari-plugin template.
Installation
First install Napari in a Python 3.9 Conda environment following these instructions :
conda create -n svetlana_env python=3.9
conda activate svetlana_env
conda install pip
python -m pip install "napari[all]"==0.4.17
Then, you can install napari_svetlana
via pip, or directly from the Napari plugin manager (see Napari documentation):
pip install napari_svetlana
WARNING:
If you have a Cuda compatible GPU on your computer, some computations may be accelerated using Cupy. Unfortunately, Cupy needs Cudatoolkit to be installed. This library can only be installed via Conda while the plugin is a pip plugin, so it must be installed manually for the moment:
conda install cudatoolkit=10.2
Also note that the library (Cucim) that we use to improve these performances, computing morphological operations on GPU is unfortunately only available for Linux systems. Hence, if you are a Windows user, this installation is not necessary.
Tutorial
Many advanced features are available in Svetlana, such as data augmentation or contextual information reduction, to optimize the performance of your classifier. Thus, we strongly encourage you to check our Youtube tutorial and our documentation. A button called TRY ON DEMO IMAGE is available in the annotation plugin and enables you to apply the YouTube tutorial to the same test images to learn how to use the plugin. Feel free to try it to test all the features that Svetlana offers.
Similar Napari plugins
Joel Luethi developed a similar method for objects classification called napari feature classifier. Also, apoc by Robert Haase is available in Napari for pixels and objects classification.
