Wow, just implemented the new Cellpose-SAM from @computingnature.bsky.social in NimbusImage and it's *awesome*! Give it a try!

My #BioimageTooloftheDay is an easy one: Cellpose by @computingnature.neuromatch.social.ap.brid.gy and colleagues
An awesome DL-segmentation network to segment cells from microscopy images

When we do not use StarDist, we use Cellpose 😀
Cellpose 2.0: how to train your own model - Nature Methods
Cellpose 2.0 improves cell segmentation by offering pretrained models that can be fine-tuned using a human-in-the-loop training pipeline and fewer than 1,000 user-annotated regions of interest.

Bring your samples into focus! A new version of the #Cellpose cell boundary mapping tool, developed at @hhmijanelia.bsky.social by @computingnature.bsky.social and @marius10p.bsky.social, now works on less-than-perfect microscopy images that are noisy, blurry, or undersampled.
Newest version of Cellpose can spot cell boundaries even in cloudy conditions
Picking out individual cells in distorted microscopy images is now as easy as clicking a button. A new version of Cellpose – the popular tool that maps the boundaries of diverse cells in microscopy

- new Cellpose 3 integration

Cellpose 3 is wonderful, easier to install and supports GPUs everywhere.

Cellpose-SAM outperforms human-to-human agreement and approaches an estimated absolute bound on performance.

Everyone in the lab is raving about Cellpose-SAM. Segmenting the previously unsegmentable across a range of different cell types and markers.

We combined:
1) SAM, a pretrained foundation model with good generalization properties.
2) Cellpose, a good cellular segmentation framework.

forum.image.sc/t/cellpose-3... Interesting forum question on 3D Cellpose that isn't answered yet. I played around a bit this morning but couldn't quite figure it out. Love to hear from others who work with 3D Cellpose (or other 3D segmentation methods)

A lot happening for microscopy segmentation. Thanks for highlighting our paper and CellPose 3, Rita!
So much happening in the segmentation space for bioimage analysis. These two papers that were published online today really stood out to me as noteworthy (a thread).

Reworked the Cellpose integration, and add Omnipose and Cellpose-SAM

The Cellpose integration has been rewritten in full. You will now find the following detectors:

I'm considering creating a video tutorial on bioimage analysis with PyImageJ, TrackMate, and Cellpose. It would focus on simplifying installation and include examples like multi-level tracking with single-cell and single-bacteria tracking within cells. Would anyone be interested?
