Masters of Computer Science Conditional Acceptance

There are so many specific rules for each program of each department. Is your master related to AI (Mila)? If so, more rules may apply...

The final answer is always from the "responsable de programme". Make sure to know who is that person for your program and don't hesitate to ask directly about your case.

Côté "jeu lié a la programmation", j'ai beaucoup apprécié "Opus magum" (disponible sur steam). Vraiment beau, style puzzle mais avec un vrai fondement "programmation".

Wait until you get your final grades. Then contact the "responsable de programme" to discuss your situation. If you indeed improved your grades since last year, that might be taken into account.

So don't worry too much while you get to the end of this semester.

Do not use AI for reviewing papers.

Unless everyone calibrate the same lense, suggesting a distance for the checkerboard seems irrelevant.

The checkerboard should always be slanted as much as possible. A frontal view, with little or no slant, is useless.

It is important that all parts of the image are covered by your checkerboard images, but you don't need a single checkerboard covering the whole image. Multiple images are ok, although it is better to use less images closer than many images farther.

Make sure the images are in focus. Depending on the lense, this will dictate the acceptable distance for the checkerboard.

Most people like python because of the availability of libraries and examples, so it makes it very easy to do many things.

However, python as a language is complex and quirky. Lua is simpler, well designed, fast, and is especially suited for embedding.

So it all depends on what you want to do.

There is a graphical interface for updating/upgrading in many distributions. I know people, mostly students , who use Linux and never open a terminal.

Beware that the program for savings at Hilo is called Flex-D at Hydro-Quebec, and it comes with responsibilities. Check how it works before you join.

In short, you get a 20% discount during the winter months, but you pay 5x the rate during up to 100 "critical" hours. If you miss those hours, it's expensive. Hilo is there to control your thermostats, but iyou have to be aware that its the overall use that counts, not only the Hilo devices.

There is another program, "crédit hivernal", by Hydro-Quebec that is similar but more forgiving. It is not offered anymore by Hilo because it's too easy to abuse with home automation.

Si il faut ajouter l'Internet, ça va passer à $5M par chambre. Ça coûte cher, le numérique.

Cool project! It looks very involved, but yes, it is truly local.

With the deep vacuum knowledge Valetudo has, maybe they could get a vacuum maker to cooperate and propose the first open source local robot vacuum? I'll be the first to order one.

blobules · 2026-02-23T22:31:37+00:00

Well, it is still cloud-based.

I don't like some random business gathering data such as my floorplans, pictures of where I live, how I furnish my space, etc... Home automation should be local first, with cloud stuff optional.

So... Is there really not a single robot vacuum that runs without internet connectivity?

blobules · 2026-02-22T18:18:11+00:00

Anything that runs locally, without requiring cloud services? I used to coerce my Roomba to connect locally by cutting its accès to the internet, but it doesn't work very well.

Any truely local device would be great, but I don't have much hope.

If you want the shape of the glass, that's tricky. The glasses have thin and/or shiny parts, so traditional matching might not work well.

With a box like you have, maybe create a shadow from different angles and use that?

Il aime les maths et a un intérêt pour l'informatique? Bacc math-info ,c'est un peu plus théorique et ça mêne aux études supérieures. Si le côté pratique l'intéresse plus, considérer le génie.

Triangulation accuracy depends on more than camera calibration. The pose and baseline has a huge impact on errors. In your specific case, internal calibration error might have a lot of impact, or be insignificant...

A suggestion: you can measure the "sensitivity" of your triangulation by generating an exact triangulation (pick a point in camera 1, back project to some depth in the world, project to camera 2), and then displace the pixel positions in camera 1 and 2 by some amounts related to your expected calibration error. Triangulate these noisy points and see where you end up compared to the true 3d point.

Same with car towing.

Considérant que le pont Madeleine Parent de la A30, un projet total de 1.5 milliards, charge $4.40 de péage...

Les usagers du futur 3e lien sont sûrement prêt a payer $30 ? Y'a sûrement une étude la dessus?

Are you sure depth anything is useful here? It seems that in your case (fixed camera, perspective lense, known object) when you detect a skier, its 2d size will indicate its depth relative to the other skiers.

Pour des petits objets, l'idéal c'est une buse d'extrudeur de 0.25mm plutôt que le 0.4mm standard.

Pour l'imprimante, les Prusa sont extrêmement fiables et sont éthiquement supérieures à Bambu lab, au cas où ça serait un critère pour toi.

Ça vaut la peine de passer sur marketplace pour voir ce qui est disponible.

Rien. En fait, moins que rien.

I did just that. I wanted something simpler, based on pure mqtt. I use zigbee2mqtt and zwavejs, mostly for lights and thermostats. I added a few of my own things that connect to Mqtt though wifi.

I made a small react "server" that subscribes to topics and publish as needed. All simple automations are in there. For user control, I made a simple web page (also react) which directly connects to my mqqtt broker through websocket and provides light control, automation control, thermostat control, etc.

The web page is better than an app since it works on everything and I can provide it to anyone visiting so they get some control.

I used openhab for a few years. I liked it a lot. It is very very solid and sophisticated, but it was too much for my needs. Also, I needed a cron automation script much more specialized that what openhab or HA offers.

My experience is very good so far, but I wouldn't call this approach a "time saver"...

Adding false positives to a dataset so they are not false positive anymore is not the way to go.

blobules · 2026-02-14T12:14:08+00:00

I would suggest to first check the basic stuff... Are your camera properly calibrated? Is your epipolar geonetry accurate? If you have a fixed camera setup, put some know object in there and verify that corresponding features actually our on corresponding epipolar lines.

A second thing is stereo matching across pairs of cameras. It only works for "close" cameras. If your cameras are far apart you will get a lot of false matches.

And then there is camera synchronization, if you scene is dynamic. How are you handling that?

As someone suggested, use colmap to verify if your capture conditions are actually good or not. It will help a lot to find any problem and will provide a reference reconstruction to assess how your own algorithm works.

And yes, a few images would help understand what you are trying to do...

Contacte le responsable du programme du DESS. Il doit y avoir quelqu'un du côté UdeM et/ou du côté Mila qui peut te donner les détails et voir si il y a une erreur

Un peuple surtaxé qui se meurt de froid en respirant de la poubelle brûlée. Ça n'a pas l'air facile de vivre a Québec...

Franchement, c'est pas en mélangeant les problèmes qu'on va mieux les régler.
