📌 Tracking cell dynamics just got smarter!
We use Bayesian linking algorithms — KOFT and SKT — implemented in our ByoTrack 🐍 Python library.
Kalman filters + optical flow for links & mitosis detection.

Yes! The code is distributed in Python in the open-source ByoTrack library. A python script (cli) is available, as well as a standalone executable for Linux/MacOs. It can be found on the CTC website associated to our submission: celltrackingchallenge.net/participants...

Exactly! In this case, we are relying on Farneback to solve our optical flow.

Zoom into a human cell infected by Shigella, the bacteria behind dysentery. Using cryo-EM, @leaswistak.bsky.social and team revealed how it pierces cells with molecular syringes. Stunning science at the nanoscale.

👉To classify the dynamic behaviors governing biological particles, we developed a neural network model based on geometric trajectory descriptors and a framework to robustly detect dynamic changes in compound trajectories.

The stiffness of cells and their nuclei is a biomarker of several pathologies, yet is usually reduced to a single value. In our last paper, we propose a method to estimate heterogeneous maps of stiffness inside freely moving cells using only fluorescence imaging.
