LACSS

   pip install lacss

LACSS is a deep-learning model for single-cell segmentation from microscopy images. See references below:

• Communications Biology 6,232 (2023)

What's new (0.11)

You can now deploy the LACSS predictor as an GRPC server:

   python -m lacss.deploy.remote_server --modelpath=<model_file_path>

For a GUI client see the Trackmate-Lacss project, which provides a FIJI/ImageJ plugin to perform cell segmentation/tracking in an interactive manner.

Why LACSS?

LACSS is designed to utilize point labels for model training. You have three options: (1) Label each cell with a single point, (2) label each cell with a single point and then label each image with a binary mask that covers all cells, or (3) Label each cell with a separate segmentation mask (as in standard supervised training). You can of course also combined these labels in any way you want.

How to generate point label?

If your data include nuclei counter-stain, the easist way to generate point label for your image is to use a blob detection algorithm on the nuclei images:
