Had a lot fun adding new segmentation models trained on CoralscapesV2 (josauder.github.io/coralscapesv2/) and new 3D backends (VGGT-Ω and LingBot-Map) to the DeepReefMap repo (github.com/eceo-epfl/de...)! Happy I believed in learned dense 3D reconstruction wayyyy before it worked so incredibly well!

CoralscapesV2 is out! Come see my oral at the #ECCV2026 workshop on marine vision! TL;DR: 1. CoralscapesV2 is better than V1 in every way (bigger, higher quality, more diverse, more classes) 2. 65k *exhaustive* fish instance annotations (painstaking is an understatement) 3. Better models on HF 🤗!

Releasing a new version of DeepReefMap today! 🪸 Together with Hugues Sibille (EPFL), we reshaped the original DeepReefMap software to be more flexible and easier to work with!

Here's the link to the quick and dirty script to do this: github.com/josauder/cor...

Using the Coralscapes dataset, it becomes easy to transfer semantic information directly into 3D point clouds! Here's an example of a few images from a simple camera being used to make a semantic point cloud of an entire transect! #deeplearning #ai #coral #ai4conservation

New dataset & pre-print: The Coralscapes dataset for semantic scene understanding in coral reefs! 🤿🎥🐟🐠🐡 Coralscapes is the first dataset consistently annotated for general-purpose semantic segmentation in reefs, spanning 174k segmentation masks of 39 benthic classes on 2074 images!

What will be the moment where the American people finally stand up against this?
