#Sketchpose is out in @MELBAJournal ! Go read it if you are interested in training cell segmentation models using few partial annotations😀 melba-journal.org/papers/202…

Thrilled to share MyoFuse, an AI-based workflow for automated skeletal muscle cell fusion quantification! 🥳 This is a collaboration with @Benjamin_Lair_ and @CedricMoro_I2MC (@I2mcT), improving the Fusion Index (FI) measurement. Preprint: biorxiv.org/content/10.1101/…

Researchers at @Imactiv3D and @maths_toulouse aim to streamline the classification of #histopathology segmentation results by minimizing the amount of manual annotation. 🖊️ Learn about the plugin they've created to address this issue in @SciReports: go.nature.com/3VCYnKE

Find out more about InstanSeg from Thibaut himself at his Virtual I2K tutorial next week! Register at i2kconference.org/virtual.ht…

Let me introduce: InstanSeg 🦠🔬💻👩‍🔬 This *would* have been a short thread about Thibaut Goldsborough’s PhD work… but he solved too many problems. Now it's a long thread about 2 preprints, a whole new approach to cell segmentation & #opensource software to make it easy to use

Last year, we found that diffusion models are nearly bridging the gap between human and machine (diversity vs. recognizability) for drawing arxiv.org/pdf/2301.11722. This year, we’re exploring which inductive bias best captures human-like creativity in VAE latents 🎨

🚀🎉 Thrilled to share our #Neurips2024 paper: “Latent Representation Matters: Human-like Sketches in One-shot Drawing Tasks”! We pit humans vs. regularized Latent Diffusion Models in the one-shot drawing task. Who’s the best sketch master? 🖌️🤖 (1/5) arxiv.org/abs/2406.06079

🚀 Thrilled to announce #inTRACKtive: a web-based tool for exploring massive cell-tracking datasets, no software installation required! Just open your browser and dive into terabytes of developmental biology data. We used it to build the virtual embryozoo.org of tracked embryonic development datasets 🐭🪰🪱🪲🐠, but you can also use it for your own data! 🔬 Preprint: biorxiv.org/content/10.1101/… Repository: github.com/royerlab/inTRACKt… This project was spear-headed by @TeunHuijben, together with engineers Andrew Sweet and @aganders3 from @cziscience @czbbiohub #CZBiohubSF #devbio #tracking #web #visualization 🧵1/n

Our Napari plugin Svetlana (napari-hub.org/plugins/napar…) for classifying ROIs in segmentation masks has improved. Try it! 1) The unbalance between classes is now managed better. 2) An interactive loss plotting is available in the GUI. 3) An automatic check-for-updates.

I implemented an oldie-but-goodie for Jupyter Notebooks: Interactive plotting and clustering with segmented images side-by-side; new in #stackview 0.7.11: "clusterplot", inspired by the napari-clusters-plotter 🔬💻🤩 github.com/haesleinhuepf/sta…

If you're not already following @Christophe21664, you definitely should! 😉 I'm super proud of this work, and there's more on the way. In case you're curious, Chris created these images without diffusion—just pure gradient ascent on a classifier. A true magician 🐇
So Im going to start being a socially engaged scientist and post papers. Here are two: 'Feature accentuation' w/ @Napoolar , Srijani Saha, @grez72, @talia_konkle - a visualization method for revealing 'what' different features 'see' in a given image. arxiv.org/abs/2402.10039

So happy to see how far @napari_imaging has gone! The repo was created with @jnuneziglesias on the Caltrain on the way to the @ComputerHistory Museum. Fast forward 6 (!) years and napari is an essential tool for bioimaging and the Python Science ecosystem. Thanks to a thriving and tireless community! Congrats to all contributors, past and present! #SoProud
6 years ago to the minute 🥳🎂, napari co-founder @loicaroyer made the 1st commit to the “napari-core” repo. github.com/napari/napari-cor… Since then, over 150 community members have contributed to the napari code, docs, & tooling, and over 400 plugins have been developed. #napariAt6

A simple example of what Svetlana can actually achieve !
Detecting Ki67-positive cells using #Svetlana. This model was trained in just 8 seconds, relying on 4 annotations post cell segmentation via #Cellpose. 😎

A long-awaited new feature in our #BioImageAnalysis software #CellACDC is finally out! You can now easily export to video directly from the GUI. Select your preferences (contours, timestamp, scale bar etc.), click on Export, sit back and enjoy the process 😎
