laptrack 0.10.0

LapTrack

Features

Provides a robust particle tracking algorithm using the Linear Assignment Problem, with various cost functions for linking.

See the publication and associated repository for the algorithm and parameter optimization by Ray-Tune.

Requirements

Python >= 3.7.11 is supported. The software is tested against Python 3.7-3.10 in Ubuntu, and 3.10 in MacOS and Windows environments, but the other combinations should also be fine. Please file an issue if you encounter any problem.

Installation

You can install LapTrack via pip from PyPI:

$ pip install laptrack

In Google Colaboratory, try

$ pip install --upgrade laptrack spacy flask matplotlib

to update the pre-installed packages.

Usage

Please see the Usage for details. The example notebooks are provided in docs/examples.

notebook name	short description	Google Colaboratory
api_example.ipynb	Introducing the package API by a simple example.
bright_spots.ipynb	Application example: detecting bright spots by scikit-image blob_log and tracking them.
cell_segmentation.ipynb	Application example: tracking centroids of the segmented C2C12 cells undergoing divisions.
napari_interactive_fix.ipynb	Illustrates the usage of the ground-truth-preserved tracking with napari.
overlap_tracking.ipynb	Illustrates the usage of the custom metric to use segmentation overlaps for tracking.

The API reference covers the main classes and functions provided by LapTrack.
