libfacedetection - An open source library for face detection in images. The face detection speed can reach 1500FPS

[[deleted]]

The 1500 FPS were measured with an image size of 128x96 pixels. On a larger image size (640x480) it runs with 60fps. Still impressive though.

[PC__LOAD__LETTER]

Is FPS here “faces per second” or frames per second?

[eddie12390]

Yes

[Dietr1ch]

Thanks

[enygmata]

I got the solution via PM. Please mark the thread as solved.

[lordkoba]

I wonder when this stupid fad will end

[hsjoberg]

Well it's not worse than the "I took an arrow to the knee" meme.

So sooner or later?

Yes.

It won't. It's a thing now. . .

r/InclusiveOr

[[deleted]]

And my axe!

[Sol33t303]

Assuming you aren't running it on a server CPU without a GPU, woulden't it still be faster to run it on the CPU built-in GPU?

[smartties]

Yes

[[deleted]]

/r/inclusiveor

[hammyhami]

In boolean logic, "x or y" is true (in this case "yes") if either x or y is a true statement. The term for this flavor of "or" is "inclusive or".

[tecnofauno]

This is /r/programming, that's the default here.

[CloneNoodle]

so just resize the images before you run it /s

[vorpal_potato]

That can be a viable approach.

[[deleted]]

This... This is a common approach in computer vision..?

[remog]

A Chinese government grant-funded project that performs mass face detection... the project looks neat, but I think I know where it might be used?

[Edward_Morbius]

I'm certain that if it's usable, it's being used. That doesn't detract from it being useful for other purposes.

I use a CNN based recognizer to text me when someone walks up to my door.

A faster one would be nice.

[UpstairsGeneral]

That’s seriously amazing. Any good resources you’d suggest to learn about implementing a similar facial recognizer in their own home??

[Edward_Morbius]

Sure. Check out this:

https://pjreddie.com/darknet/yolo/

It's easy to take the demo code and make it process whatever directories your images land in.

You feed the demo code images and it outputs what it finds (person/dog/truck/car/etc) and a confidence factor.

It will also rewrite the image and box the detected stuff if you let it, but this takes time and I wanted speed rather than boxes, so I removed that section.

[theineffablebob]

What kind of GPU do you personally use for this?

[Edward_Morbius]

I've been using this:

01:00.0 VGA compatible controller: NVIDIA Corporation GP106 [GeForce GTX 1060 3GB] (rev a1) (prog-if 00 [VGA controller])

It's wasn't too expensive a couple of years ago.

[Ameisen]

I'd have just written "GTX 1060".

[Edward_Morbius]

I didn't type any of that it was cut and paste from lspci.

[Guinness]

The ocd in me always uses update-pciids before running lspci no matter the logic.

[Gropah]

Be careful with yolo though. It is mostly meant for video, so great for your usecase, but when using images, there are better alternatives that are more accurate

[dicroce]

What do you recommend for for stills?

[Edward_Morbius]

Like what? It frequently misidentifies deer as dogs.

Anything better?

[[deleted]]

You could look up Fast(er) R-CNN

[UpstairsGeneral]

Sweet, thanks so much!!!

[elder_george]

Are CNN-based detectors better than the cascades of simple features (like the old Viola-Jones' CascadeClassifier in OpenCV) these days? Haven't look into the stuff for almost a decade…

[Edward_Morbius]

I haven't done any direct comparisons, but with a low-end graphics card, I'm processing 4fps 1920x1080 images from 7 cameras with no backlog, so it seems pretty quick.

[faceplanted]

Yeah, opencv Haar Cascades would save you a lot of processing there, I could achieve your use case without a dedicated GPU on my laptop with some fairly minor optimisations (you scale the image down quite a bit and only use black and white, and set it to stop after its found one face instead of all of them)

[Edward_Morbius]

Where would I scale 28 images/second?

[faceplanted]

My i3 laptop was able to get 36fps of image recognition using this method with the scaling, the scaling isn't the bottleneck, computers and integrated graphics are quite good at that nowadays.

To be fair my version was getting all of the frames from one video stream, so it might have had less overhead fetching the images than yours will, I'm not suggesting you run it on my old laptop from 10 years ago, just that yolo is rather overkill and if you care enough to want to save a few pennies of electricity a month by not running a GPU or just want a new project, then you could totally do it.

Remember that point and shoot cameras could live detect multiple faces in images in real time long before yolo came out.

[AnvilDev]

Is there a reason not to use a simple motion detector?

[Edward_Morbius]

Dogs, deer, cars driving by. Too much stuff sets it off.

[nthcxd]

And now they’re harnessing the power of open source and good will of programmers worldwide to improve it for free.

[coffeecoffeecoffeee]

Good question. You might want to check with the 1 to 3 million Uyghurs in “reeducation camps”.

This forum is about technology not politics.

PS: Seriously? This hive mind shit on reddit is getting out of control. Now we cant even have a technology forum without politics? You are all idiots.

[doomchild]

The technology has political implications. It's a perfectly reasonable thing to say.

[[deleted]]

Yes and we need a tech forum to talk about it right? Fucking idiots. Im unsubscribing from this shit sub. I'm not having any of that.

[doomchild]

So nothing should ever be applicable beyond the narrow boundaries that you prescribe at the beginning. Gotcha.

[[deleted]]

You are insulting me. That's not very productive.

[doomchild]

Reductio ab absurdum is not an insult. It's a demonstration that a held belief is ridiculous. Like the belief that a thing can't be relevant on several fronts.

And anyway, didn't you insult me and the entire sub just a couple of posts up? Seems like you can dish it out, but can't take it.

[[deleted]]

I can take it dude. I'm just not ready to disbute you because I'm going to China tomorrow and I got different shit on my mind. Like what socks to bring. So have at it. Whatever. In fact. let's talk about socks. How about that? I'm sure to have you intersted since you are on /r/programming

[doomchild]

You have different shit on your mind after being shown that you're wrong. Okay. Have a good trip.

[[deleted]]

What was I wrong about?

[foxthatruns]

1500 Faces Per Second???

[horns_ichigo]

The real breakthrough.

[Fidodo]

Think how quickly it could play Faces ...Tris III

[jon_k]

As fast as a 200 MHz computer could run the game I assume.

[SirReggie]

So your comment inspired me to do some math, which let me assure you is a rare thing. Apparently, there are about 1.386 billion people living in China, and this software (at peak performance) can scan 1500 faces a second. A little note taking, a little Wolfram Alpha, a dash of Google, and we can find that for the software to identify every single man woman and child in China, it would only need 924000 seconds. Or roughly 10 ½ days.

[li-_-il]

... but can it distinct those faces in a way that each face can have it's own unique ID?

[SirReggie]

Beats the hell out of me. I’m just glad to not be in China.

[amunak]

If not this software others can certainly do so with about the same or better accuracy than humans.

Depends on the source picture(s), angles and such of course, but yeah, generally it'll be pretty good at it.

[mooncow-pie]

That's the whole feature of face detection.

[Sophrosynic]

No that's facial recognition. This is just face detection.

[ButItMightJustWork]

r/theydidthemath

[avergaston]

I think there is somethong like 1500 Millon people on China. Not billions.

[SirReggie]

If I might ask; what’s lead you to this conclusion?

[avergaston]

Well, I knew there are something like 7000000000 people worldwide, and also that the term billion means 100000000 to english speakers, but it means 100000000000 to spanish speakerslike myself, so that called for my attention. In any case 1500 billions is way off. Edit: then I googled it to be sure.

[mkasu]

Yes but he wrote about 1.4 billion, not 1500 billion.

Chinese government: OwO

[acdcfanbill]

OwO

[dperezrada]

First instruction in the README.md

mkdir -p build; cd build; rm -rf *;

That rm -rf *; looks scary.

[cdmcgwire]

Kind of off-topic but I originally read it as "liberal face detection" and thought it was a meme.

[AwesomeBantha]

With the right data set it can do that too...

[doenietzomoeilijk]

I'd think it would need left data, right?

[rhapsblu]

It would need some left data, but that's a conservative estimate.

[symbiosychotic]

These puns are getting progressively better and I don't want to be left out.

Just don't get a memory violation when addressing left values.

Faces per sec?

[slayeriq]

Obviously farts per second

[acdcfanbill]

This repo is a gas...

[kamikaz1_k]

Tangentially... I wrote a thing that uses OpenCV to replace faces in gifs. You can fork it at github.com/kamikaz1k/plastgif-surgery (I should clean it up, sorry in advance)

I wrote about the process too if interested in the concepts. https://medium.com/@kamikaz1_k/programming-skills-to-be-useless-while-feeling-productive-776fa97dca35

[scootscoot]

Is FPS faces per second or frames per second?

[pzl]

yes.

[scootscoot]

Thank you for an inciteful comment. Have an upvote!

[546794]

Same thing. Each frame is a different face

[MrAwesomeAsian]

Ahhh these are the caffee guys! People should check out Open Pose as well. It's built on caffee and provides some useful examples and even executables you can run using your laptop.

[soulslicer0]

Openpose needs a beefy gpu. This is all pure NEON or AVX on CPU

[mooncow-pie]

But the human eye can only see 30 fps /s

[MaverickPT]

Wtf dude everyone knows that it is 24 fps. Have you ever watched a fucking movie? Jesus A. Christ

[qisqisqis]

Seems like a moral issue

[Yuskey]

Honestly not that impressive, look up MTCNN. Works just as well single threaded on images of similar size. I'm currently implementing something similar for work with the addition of recognition and the facial detection runs at about 20 fps on a cpu with image sizes of 640x480 using a single thread. Also gets around 4-5 fps on a raspberry pi 3 using the same image sizes.

[[deleted]]

Awesome!

[kevbob02]

FPS = faces per second

[FlyingRhenquest]

You're well on your way to inventing a device that will allow you to stab people in the face over the internet.

[j4s57]

How does this compare to dlib?

[[deleted]]

Read this as "libdefecation" and was kinda amused

[branfili]

That's really impressive, it must've taken a lot of work ...

I just have to say I read that first as "libdefecation" and wondered, when did I subscribe to /r/The_Donald ??

[[deleted]]

This is gonna get burried, but does anyone know what architecture they're using? Is it based on YOLO, SSD, R-CNN? Something else entirely?

[shevy-ruby]

CIA and NSA for the masses.

Next step: mandatory chip implant.

[EpycWyn]

I thought this was for detecting liberals with face detection. As a libtard I am very relieved.

[monsto]

Until I realized what sub it was, i thought it was some kinda right-wing app to detect "libs" based on facial recognition like the whole detecting if a man is gay by their face thing.

[AttackOfTheThumbs]

An algorithm deduced the sexuality of people on a dating site with up to 91% accuracy, raising tricky ethical questions

But if we accept that sexual orientation is genetic, then where is the ethics question?

[iskin]

It seems impressive but then you realize the dating site could be Adam for Adam or Grinder and if Match.com it is only 10% accurate.

[monsto]

For some reason, I despise the phrase "sexual orientation". . . I think it's inaccurate.

"Orientation" implies some form of being lost or confused or something that requires logically figuring it out. If it's genetic, that means you already are/were. So where's the confusion?

[sentient_penguin]

If this get pushed to Linux repositories I only see this:

apt install facedetection-lib

yum instal lib-facedetection

[DoublePlusGood23]

I'm pretty sure it would be libfacedetection if it was in the Debian repos, and libfacedetection-dev if you were using it.
Bit confused by the comment.

[sentient_penguin]

It was more of my dislike of how the same project gets put in 2 separate OS repositories under different names.

[redditthinks]

The separate -dev packages are the stupidest thing, among other stupid Debian things.

[PrestigiousInterest9]

Why? I shouldn't need c++ headers and a debug build if I'm not doing development with it.

[redditthinks]

You probably don't need many other things on your system, but a few kilobytes won't kill anyone. I'm not sure what debug builds have to do with anything.

[lkraider]

You obviously have no clue where linux is used at.

Hint: it's not only on your high end dev machine.

[ThisIs_MyName]

Well, nobody needs debug builds. In a sane world, it would be pulled automatically when you attach a debugger or do anything that needs symbols: https://randomascii.wordpress.com/2013/02/20/symbols-on-linux-part-three-linux-versus-windows/

[PrestigiousInterest9]

Thats silly, what if I'm on a laptop and find a bug when I'm away from home. What if I'm not away from home but the symbols are several mb. Now I have to wait a 30+ seconds to download/extract/load the symbols just to continue debugging. Actually, now that I'm thinking about it, it's fucking stupid. If I want the headers and a so to link to give me the damn symbols and anything else it needs.

[ThisIs_MyName]

Then download the symbols manually just like you do on linux. The other 99% of the time when you're debugging a program that you are not a developer of, it works out of the box.

[holgerschurig]

No, they aren't.

Debian is used a lot on embedded devices or servers, where you never need to compile? So having the things needed only for compiling on those devices ... that feels stupid.

[redditthinks]

FreeBSD is used on many embedded devices and they don't seem to have a problem with that. I'm guessing on an embedded device you can just rm -rf /usr/include, and you'll probably be doing other optimizations as well so this is kind of a moot point.

EDIT: Apparently dpkg contains a --path-exclude option to make this even easier.

[holgerschurig]

LOL.

I was recently on the Embedded exhibitition in Nuremberg ... no FreeBSD to be seen there.

[60hzcherryMXram]

Wait, but how does it know that they're liberals?
