No such thing. Ask away!

!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must be legitimate questions. All post titles must include a question.

All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.



Rule 2- Your question subject cannot be illegal or NSFW material.

Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.



Rule 3- Do not seek mental, medical and professional help here.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.



Rule 4- No self promotion or upvote-farming of any kind.

That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding META posts and joke questions.

Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.

On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.

If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.



Rule 7- You can't intentionally annoy, mock, or harass other members.

If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.



Rule 8- All comments should try to stay relevant to their parent content.



Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.



Rule 10- Majority of bots aren't allowed to participate here. This includes using AI responses and summaries.

It is being called "cv dazzle" to defeat facial recognition like that used by Facebook.

I'm wondering if anyone has experience using this in protest, or if you've heard local coverage about it?

LOL. No such thing exists in the way you're alluding to. What crazy conspiracy subreddit did you get that on?

You peasants may be too poor to know the technology. Go search it up.

[–] just_another_person@lemmy.world 3 points 2 days ago (1 children)

I work in this field. No such thing exists. Thermal Imaging, including FLR, doesn't have the contours in 2D images needed to profile anything at all. There is no such thing as a depth ranging thermal camera sensor with complex stereoscopic images that can service contours for inference. It doesn't exist.

Straight from the USA army military website. I guess you just think are competent at your job. It DOES exist.

Your take on this is inaccurate, and this is not "facial recognition". This is pattern recognition, and shoddy at best from the description. It's using converted 2D imaging data with heat sensor data, and reduxing the resolution down to another 2D map, and ATTEMPTING to make a match. This is what we would call "fuzzy" recognition, and is not accurate at all. Fuzzy inference takes any range of accuracy as a success, meaning if it gets it right 5% of the time, it's considered accurate.

Bottom of the barrel bullshit that doesn't work. Don't even take my word for it, you can look up this same pipeline model of inference in countless GitHub repos that the original work came from and understand why.

Here's an example:

  • Person 1 goes for a run, then turns direct to FLR camera
  • Person 2 who looks similar, but 50lbs heavier walks out of their house and walks towards camera
  • 15% match on inference

The military would consider this a detection.

YOU on the other hand are talking some crazy conspiracy theory noise about how these cameras are used in crowds and can differentiate using heat detection maps on people wearing face paint.

NOT HOW THAT WORKS

This is saying they can map thermal to known faces. But this is far from being able to read faces through materials. Thermal/infrared doesn't provide that kind functionality, at least to my knowledge the signal would bleed into the mask. It could work for glasses or maybe thin masks.

Look, the government lies and lies some more. This would be damning if people realize they have this stuff. That article is from 2018, they just aren't telling you or anyone else over a megaphone.

[–] Proprietary_Blend@lemmy.world 2 points 2 days ago (1 children)

Can you just post all the applicable research in an easy-to-follow format that I can copy/paste into an angry email to someone? Cool.

Otherwise you're a Nazi somehow.

/S

[–] lunatique@lemmy.ml -4 points 2 days ago

Use an search engine. Why do i have to do your homework? Do i have to tuck you in at night and read you a bedtime story too? Also you calling someone a Nazi because they didn't do something for you is a highlight of your dullness. The irony
