It finally snowed on our mountains. That's a nice change from skiing on ice.

There was about 100 km/h of wind over the Alps the other day. I went for a wave flight with Gab Bfe from Chambéry in France to Bolzano in Italy in his Stemme glider (About 800kms out and back). If you are interested in doing this yourself check out Gabriel's website www.soaring-adventures.eu

While Unsigned Distance Fields (UDFs), unlike Signed Distance Fields (SDFs), can naturally represent open surfaces, turning them into triangulated surfaces them is challenging. In a paper to appear in NeurIPs, we propose an effective iterative refinement approach. arxiv.org/abs/2407.18381 #ai

Reconstructed Viking ships in Roskilde, Denmark. Wonderful on a nice September day in port. Might have been a different story in Winter in the North Sea!

Traditional bonfire on August 1st, the Swiss National day, with Nancy for scale. Note that that there are no barriers and that can walk as close to the fire as you dare. Not something you would see in the US these days, I think.

Trying to understand how the steam engine of an early locomotive works at the York train museum. It took us a while but I think we gained a better understanding of practical thermodynamics.

While visiting friends near Sheffield, we stumbled upon Pemberley, aka Chatsworth house. Alas, Mr. Darcy was not in residence at the time. Nevertheless, It was worth seeing with our own eyes how vast such an estate is. You don't get a sense of that from the books or the movies.

In the context for my new aeronautics-related project, we are going to need some flight data to train our ML algorithms. And it needs to be acquired at a reasonable cost. So, we strapped a small GPS on a model plane and went flying. It seems to work nicely. Necessity is the mother of invention!

We released a large multi-view people-tracking dataset. We used 25 partially overlapping cameras placed over more than 400 meters. We acquired 24'000 images per camera, with full calibration data. scout.epfl.ch #VideoSurveillance #PeopleTracking #ComputerVision

In an upcoming MICCAI paper, we model the heart as interdependent SDFs representing a distinct anatomical component. By enforcing proper contact between adjacent ones, we ensure that they define anatomically and topologically correct structures. arxiv.org/abs/2307.08716

In a paper to appear at ICCV, we show how to count stacked objects such as those shown below, even though only those at the top are visible. Our key insight is that this suffices to estimate the number of objects per unit of volume. corentindumery.github.io/projects/sta...

In paper to appear in MICCAI, we propose a method that “GenAI-fies” atlas-based segmentation by training a diffusion model to learn the joint distribution of images and segmentation masks. arxiv.org/abs/2503.06748

To refresh our ideas before the conference, we went snorkeling in 3C amazingly clear water. With enough layers under our dry suits, we weren't cold. Putting one's head in the water is unpleasant initially but that passes quickly.

I have been invited to give a keynote at SCIA'05 and we took advantage of that to tour Iceland. The midnight sun yesterday night was spectacular! I highly recommend it.

Our paper written in collaboration with MBZUAI on modeling loose-fitting garments will be presented at SIGGRAPH. Crucially, we used guided diffusion models to synthesize the invisible parts while accurately modeling visible ones. arxiv.org/abs/2504.08353 #DeepLearning #Fashion

And today, @nancysuisse.bsky.social saw this beast parked at the glider field. Some people came IN STYLE for demonstration glider flights!

Supervised learning methods often assume that training and test data come from the same distribution. In a paper to appear in ICML, we show we can use idempotence to handle distribution shifts on-the-fly, without access to any additional labeled data. arxiv.org/pdf/2410.04201

Poster seen at the Lausanne train station. It advertises the fact that health-plans from “Groupe Mutuel” cover contraception. I can’t imagine seeing anything quite as explicit in a US public place.

Lab outing at the local Archery Center. I imagine some of us were thinking about Reviewer #2. It helps with accuracy ;-)

A busy 24 hours around the @iccv.bsky.social deadline: Pizza night at the lab on Friday, 15 hours to ICCV deadline; finalizing papers on Saturday morning, 10 mns to deadline; our son’s civil wedding, 4 hours after deadline; wedding dinner, 9 hours after deadline.

My Russian PhD student is defending his thesis today and he put up some bilingual slides. That's cute and I view this as one of the best answers we can give to unsavory politicians. Let's attract the best and brightest Russians to the west and then let's keep them around.

My PhD students have a good sense of humor. Seen in one of their offices after the last CVPR results were announced. Hoping for better luck this time around ;-)

I am back from visiting my “academic children” Xinchao Wang and Kaicheng Yu, now professors in Singapore and Hangzhou. They are all grown up and doing well ;-) And I am still flabbergasted at how much China has changed in the last three decades.

I am in Singapore to visit my former student Xinchao Wang, now a prof at NUS. And we stumbled upon the local version of snowboarding. It's different!

@nancysuisse.bsky.social has found a new way to do a looping. It probably wasn't planned though.

My titanium hips have now been field tested on steep terrain ( en.wikipedia.org/wiki/Pas_de_...). I am pleased to report that they work well, a mere 5 months after the second operation. The surgeon really did a good job!

After three long years, our paper on unsupervised reconstruction of a temporally consistent sequence of surfaces has finally been accepted for publication in PAMI. Remarkably, it still is current. Check it out at arxiv.org/abs/2111.06838 .

Power lines are dangerous for low-flying aircrafts, especially in low-visibility conditions. We have developed an approach to jointly detecting them and their pylons from images captured from several hundred meters away by aircraft-mounted cameras. See arxiv.org/pdf/2407.14352 to appear in MVA.
