PhD Student @EPFL and @TRSC_org Deep Learning | 3D Vision | Underwater SLAM | AI for Conservation
Lausanne, Switzerland
Joined March 2016
Looking forward to the ICCV CV4Ecology Workshop, where I'll speak about AI for coral reef monitoring! πͺΈππΈ
Excited for CV4E @ICCVConference in just 3 weeks! π Weβve got a fantastic lineup of speakers who will be giving diverse talks across ecosystems, CV methods, and real-world applications (hint: π¦πππ§¬π¦¬) - see you there!

Great work! But these kind of SfM/SLAM papers should visualize the accumulated 3D outputs. Showing per-frame 3D can be misleading, by hiding the misalignment between per-frame 3D reconstruction. For example, if the accumulated 3D output have multiple layer reconstruction for the

RGB-SLAM becomes a single forward through the network with no optimization needed. We still need to only keep keyframes to avoid exploding the costs. We simply check the 3D overlap between views and memory, ensuring new keyframes discover enough novel content...

@SecRubio This is democracy. This decision is the result of a thorough & independent investigation to protect our Constitution & the rule of law. It is independent courts that will have the final say. We have learnt from our history that rightwing extremism needs to be stopped.

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

This has been a colossal effort from the team: data acquisition, 1500+ hours of expert annotation, and benchmarking! π€ A big thank you to my co-authors @Viktor_Do_, Guilhem Banc-Prandi, Gabriela Perna, Anders Meibom, @devistuia, and all members and partners of the @trsc_org!

More details in the pre-print: https://t.co/7WvKa8QB2c Coral reefs are under unprecedented threat, and monitoring is crucial to devising and assessing effective conservation strategies. Automated coral surveys based on computer vision have potential to scale monitoring up!

Project website: https://t.co/oDv2NTCDCw, w/ code, pre-trained models, and the download. Coralscapes is deliberately designed to follow the structure of Cityscapes, facilitating the use of state-of-the-art semantic segmentation neural networks in a challenging ecological domain!

So the position of the Trump-Vance administration β and every member of Congress unless they explicitly say otherwise β is quite literally you do not have guaranteed free speech rights in America if you say things they don't like. That is the headline.
.@SecRubio on detained Turkish student: "We revoked her visa...We gave you a visa to come and study and get a degree not to become a social activist that tears up our university campuses. If we've given you a visa and then you decide to do that we're going to take it away.

So.. uhh... is anybody going to actually do anything meaningful about this? Or is it the new normal in the U.S. that those with legal status will be roughed up due to exercising their right to free speech?
Massachusetts has been welcoming students and immigrants for four centuries. The footage I saw today of Tufts graduate student Rumeysa Ozturk being detained by masked officers is contrary to that tradition. Ms. Ozturk has no reported record of violence or harassment; she did

Ukraine is Europe! We stand by Ukraine. We will step up our support to Ukraine so that they can continue to fight back the agressor. Today, it became clear that the free world needs a new leader. Itβs up to us, Europeans, to take this challenge.
