YoloV8 model for the detection of Tau fibrils in EM images.
Project description
🧬 Tau Fibrils Yolo - Object detection in EM images
We provide a YoloV8 model for the detection of oriented bounding boxes (OBBs) of Tau fibrils in EM images.

Installation
As a standalone app
Download and run the latest installer from the Releases page.
As a Python package
We recommend performing the installation in a clean Python environment. Install our package from PyPi:
pip install tau-fibrils-yolo
or from the repository:
pip install git+https://gitlab.com/center-for-imaging/tau-fibrils-object-detection.git
or clone the repository and install with:
git clone https://github.com/EPFL-Center-for-Imaging/tau-fibrils-yolo.git
cd tau-fibrils-yolo
pip install -e .
Model
The model weights (6.5 Mb) are automatically downloaded from this repository on Zenodo the first time you run inference. The model files are saved in the user home folder in the .yolo
directory.
Usage
In Napari
To use our model in Napari, start the viewer with
napari -w tau-fibrils-yolo
or open the Napari menu bar and select Plugins > Tau fibrils detection
.
Open an image using File > Open files
or drag-and-drop an image into the viewer window.
Sample data: To test the model, you can run it on our provided sample image. In Napari, open the image from File > Open Sample > [TODO - add a sample image]
.
As a library
You can run the model to detect fibrils in an image (represented as a numpy array).
from tau_fibrils_yolo import FibrilsDetector
detector = FibrilsDetector()
boxes, probabilities = detector.predict(your_image)
As a CLI
Run inference on an image from the command-line. For example:
tau_fibrils_predict_image -i /path/to/folder/image_001.tif
The command will save the segmentation next to the image:
folder/
├── image_001.tif
├── image_001_results.csv
Optionally, you can use the -r
flag to also rescale the image by a given factor.
To run inference in batch on all images in a folder, use:
tau_fibrils_predict_folder -i /path/to/folder/
This will produce:
folder/
├── image_001.tif
├── image_001_results.csv
├── image_002.tif
├── image_002_results.csv
Training
The instructions for training the model can be found here.

Acknowledgements
We would particularly like to thank Valentin Vuillon for annotating the images on which this model was trained, and for developing the preliminary code that laid the foundation for this image analysis project. The repository containing his original version of the project can be found here.
