This study presents a portable cell tracking algorithm that accurately handles cell segmentation noise, divisions, and deaths. A parameter-free option and a semi-automated framework improve tracking performance and portability across diverse biological videos.

Area of Science:

Cell biology
Computational biology
Bioimage analysis

Background:

Cell tracking is crucial for high-throughput biological studies.
Existing trackers struggle with variable cell density and dynamics, limiting their portability.
Challenges include noise in cell segmentation, cell divisions, and cell deaths.

Purpose of the Study:

To develop a portable cell tracking algorithm addressing current limitations.
To improve the robustness and generalizability of cell tracking across different experimental videos.
To introduce a parameter-free variation and a semi-automated framework for enhanced tracking.

Main Methods:

Developed a novel cell tracking algorithm with a new method for recovering cell displacement distributions.
