DINOSim Segmentation

A napari plugin for zero-shot image segmentation using DINO vision transformers.

---

Overview¶

napari-dinoSim allows users to perform zero-shot image segmentation by selecting reference points on an image. The plugin then computes similarity maps based on features extracted by DINOv2 and generates segmentation masks.

For detailed information on the widget's functionality, UI elements, and usage instructions, please refer to the Plugin Documentation. A simple example notebook demonstrating how to use DINOSim via code is also available.

Installation¶

You can install napari-dinoSim via pip. For GPU support (recommended), ensure you have a compatible PyTorch version installed with CUDA or MPS support.

pip install napari-dinosim

or from source via conda:

# Clone the repository
git clone https://github.com/AAitorG/napari-dinoSim.git
cd napari-dinoSim

# Create and activate the conda environment
conda env create -f environment.yml
conda activate napari-dinosim

Open the Plugin¶

To launch napari, run the following command in your terminal:

napari

Within the napari interface, locate the DINOSim segmentation plugin in the Plugins section of the top bar.
