On: Ask HN: Why does Cloudflare/hCaptcha care so much ...

Whatever they're doing it's american-centric.

Identify "Crosswalks". What the hell is a crosswalk

"School bus" - what's the difference between a bus currently serving a school and another one?

"Show taxis", there are no black vehicles listed at all

[agilob → iso1631]

Or failing 3 in a row because 3 motorcycles or scooters are considered a bike. We will easily win AI uprising.

> AI uprising

There won't be one. But there will be more and more unethical rich people using Machine Learning and Deep Learning technologies and vast computing power, money, and political clout to gain things for their own, and many people will suffer or at least be worse off as a result of this.

To win we just need to print out millions of cardboard cut-outs of humans, AI won't be able to tell the difference and we can then destroy them!

I'm still not sure whether to include the squares with a tiny fraction of the border of the vehicle. And when they fail me I wonder if I'm doing the wrong thing.

[NavinF → YPPH]

The labeling instructions for every object detection dataset I’ve used say you should include every pixel of the object.

That said, I’m sure a lot of people don’t select squares that have only 1 relevant pixel so the captcha should be lenient.

Doesn't it make sense to make taxis bright colors so they're easier to see? Why would you paint them black?

[fennecfoxen → cdot2]

Because WWII era London sensibilities. Now it’s a tradition.

[cdot2 → fennecfoxen]

That's very English.

It's pretty obvious from the pictures. I get that it's US centric, but if you can't figure those basics out, you probably shouldn't be passing the captcha.

[austinjp → cheeze]

What sort of internet do we want? One where every captcha is only useful to US companies, regardless of who has to pass it?

Even though it's US-centric, it's still easy to do correctly for most non-US English speakers, even for non-natives.
