Excited to share our new paper (CVPR 2026 πŸš€): "MuViT: Multi-Resolution Vision Transformers for Learning Across Scales in Microscopy" which enables local predictions to use global context.
Great work led by @albertdm.bsky.social & another fun collab w @gioelelamanno.bsky.social! @scadsai.bsky.social

It's ok I guess I'll click on some cars or bikes to get my open-source PRs merged now

We push the SOTA in bacteria tracking once more, the remaining errors are almost cut in half πŸŽ‰

This work was spearheaded by the super-talented Cyril Achard in @maweigert.bsky.social's group πŸ‘

For more on transformer-based tracking with pre-trained features, check github.com/C-Achard/Tra...

πŸš€β­οΈ Trackastra update πŸš€β­οΈ

We just released a new model that uses pre-trained image features from Meta’s SAM2 model.

This improves performance on many datasets, most notably for bacteria tracking.

To give it a try, simply install with the new optional dep `etultra` github.com/weigertlab/t...

Yes, and there is already a pretrained model trained on all Cell Tracking Challenge data, 2d + 3d.

We moved the AI@MBL course "Deep Learning for Microscopy Image Analysis" to HHMI Janelia (@hhmijanelia.bsky.social).

Join us for two weeks of intense lectures, exercise, and hands-on project work!

Course dates: June 4-18 2026
Application by: January 15 2026

TrackMate Trackastra Trackastra integration in TrackMate.

Trackastra is part of the brand-new TrackMate v8.

It is the first deep-learning-based ("AI") drop-in replacement for TrackMate's regular LAP-Track algorithm.

Tracks out of the box for many types of datasets (bacteria, fluorescent nuclei, phase contrast cell culture etc), zero parameters to tune πŸ€–

Preprint -
Excited to present WHOLISTIC, which extends the concept of whole-brain functional imaging to the entire body. Pioneering work by incredibly talented Virginia Ruetten @vmsruetten.bsky.social, this platform reveals whole-organism cellular dynamics in vivo.

So cool! Causal up until the penultimate layer, I bet the DiGradCam will look interesting. Also, as commonly known, if you can 3d print your neural network architecture you get to name it! GiuseppeNet ;) ?

I love that! A simple thing might be to spin out orthogonal to the major axis (of movement) in the few previous frames, and the sample could be rotated according to that. Not sure if our brains are ready to deal with that

Bonus: I added a 3D version, here is an example on the C. elegans dataset from the Cell Tracking Challenge.

I originally made these when developing my tracking algorithm Trackastra www.ecva.net/papers/eccv_..., and have finally made them easy-to-produce for anyone at this year's @hhmijanelia.bsky.social Trackathon.

Cell tracking is never perfect, and it's important to understand the types of errors your solution contains.

Here is my stab at this: Divisualisations in @napari.org. github.com/bentaculum/d...

You spin tracks out upwards from the playing video. Green edges are correct, FP in magenta, FN in cyan.

Looking for a great PhD position?
I had the pleasure of doing my doctoral research in Martin’s group - wholeheartedly recommended :)

First post and little update:

I’m super excited to share that I moved to the Bay Area and joined CZI as a Senior Research Scientist to continue working on Imaging & AI.
