🧪 Now we’re talking – Episode 5:
Meet the gel permeation chromatograph! This machine helps us understand how big (or small) molecules really are 🧬 — and plays a key role in basic research at Hof University of Applied Sciences.

Picture of GPC and Johannes Küfner with short informations about the machine. The machine is supervised at the Institute for Circular Economy of Bio:Polymers (ibp) by Johannes Küfner and Benedikt Hiller, both research assistants, David Krieg, deputy research group leader and Lucas Großmann, deputy head of the institute.

Wanna use computer vision for more than image rendering?

Pre-print alert: we published on arxiv our preprint on building FEA-compatible voxel-based RGB+Thermal 3D models, effectively bridging computer vision and simulation in one framework (https://arxiv.org/abs/2504.04448).

While there is still some limitations to this work (e.g. related to surface reconstruction) I hope this work can be the catalyst to more research in using computer vision in #AppliedScience !

👩‍🔬 Thanks to all the co-authors: Etienne Chassaing, Florent Forest, and Olga Fink.

See some teaser images from the paper, where we run FEA on a 3D model built from computer vision without post-processing!

#computervision #fea #simulation #voxel #thermal #sustainability

The images shows a table of the results over multiple dataset. Comparing thermoxel to plenixel it shows that thermoxel is able to generate geometrically correct meshes and that finite elements analysis can be run on the meshes without pre processing

I don’t know Joe, but I came across Joe’s work in my role as a geologist (the world topobathy image), and I was impressed so I sought out more; I think you will be impressed as well… [not considered a specific endorsement though, just my personal opinion, you know the drill]…
