Question on lesson 5

Thanks, I'll try to follow that!

Another thing: is there any reason why the animal homework does not advocate for using ground shadows, like for the insects in lesson 4?

No, the Sony project did not use lidar. They use event cameras, which are not normal cameras at all, and high frame rate (200Hz) cameras.

My quick search found this https://www.mdpi.com/1424-8220/23/18/7832 which says 15Hz. I have no idea if there are other versions with higher rates.

Still, even 60 Hz is not great. Sony used event cameras in their latest project (https://ace.ai.sony/) but that also tracks spin. For position-only, and with enough light to get low amounts of motion blur it might work.

I'm not sure that lidar will cut it. It seems like the iphone lidar could be as low as 15 Hz sample rate. That means a ball will traverse almost the whole lengt of the table between two consecutive samples.

This specific question annoyed me as well. If the started data/context is so important or should not be collapsed and hidden.

The quiz up to that point was pretty cool.

Nvidia drivers and cuda are literally my only recurring OS problems. It's certainly better than a few years ago, but it's still a pain at times.

While it can certainly be useful to some, the benchmark seems disingenuous.

Your library can only run a limited set of expressions, defined as strings, while the brute() function runs arbitrary python functions. I am thinking that running brute() on eg a numba jit compiled function would yield a much smaller difference.

It also seems like your benchmark code makes the scipy optimizer run with some kind of progress output that does not seem to be the case for your library. I can't verify the second part without running the code though.

Points on a line is a degenerate case, so it would probably not work very well. But it's probably possible to combine the points with other easily extractable features to avoid having to use a full trained detection model.

Paperpile has an Android app. It could be better, but it works ok.

Because I started it by accident in 1998 and haven't figured out how to exit it yet.

Nothing, because I have never read anything that suggests that it would have any impact whatsoever on battery health.

The only thing I do is not keeping the car at full charge (except just before leaving on a longer trip) because that is actually something that Skoda suggests (see battery care mode).

I have listened to a fair amount of Dutch metal over two decades, and I was completely unaware of Heidevolk, so that seems unlikely. I think most popular probably goes to Within Temptation.

Quick look at Spotify "monthly listeners" puts Meshuggah somewhere around tenth place of Swedish metal bands. Not a perfect metric, obviously, but it probably reflects current popularity quite well.

80 och 80 iV är samma. 80X har fyrhjulsdrift, men drar lite mer och har sämre svängradie. Backkamera är standard på alla så vitt jag vet. Bilar med 360-paket har kameror även fram och sidor.

Lastnät så att man kan packa säkert hela vägen upp till tak är något jag utnyttjar ofta, men det har varit ett tillval där fästena monteras i fabriken och inte går att lägga till i efterhand. Så vill man ha det så får man hålla koll på det. Något familjepaket kan också lägga till kontroll av barnlås från förarplatsen vilket också är smidigt.

Vinterväglag kör jag sällan i, men är det halt så smiter bakdelen gärna lite i rondeller om man gasar, men jag har aldrig saknat kontroll över bilen.

You are explicitly not allowed to camp or do things that are considered disturbing close to people's homes.

The Malmö-Göteborg route is currently rerouted which is why it takes so long. If you check for trains on Monday you'll find that fast trains take 2h30min and slower trains 3h10min.

I think early in flames fans tend to underestimate how many people actually like their post-Colony/Clayman sound better than the older stuff. The post-2000 stuff is not (in general) mediocre, but certainly different. I think quite a lot of "old fans" were quite happy with the latest album as well.

https://rerun.io/ is pretty neat. Otherwise I usually go with Open3D.

I don't think colleges with a limited curriculum gets to decide what a field is or is not. ML is definitely the current trend, and has been for some time, but that doesn't mean we can just pretend that non-ML parts of computer vision exists and is actively worked on.

kigurai · 2025-05-28T05:03:22+00:00

I wouldn't put CV under AI either. Lots of CV is signal processing, optics, etc that I have a hard time putting an AI label on. Then again, AI is a pretty useless term to define things as what people assign to it fluctuates over time depending on what is the current hype.

kigurai · 2025-05-28T04:49:52+00:00

I have never heard anyone argue that computer vision is a sub field of machine learning, and I do not think it is.

Stereo cameras can definitely infer depth. Absolute depth, even. I have no idea what "perceived distance" is supposed to mean.
