Real-Time, Detailed Face Tracking On a Nokia N900

Soulskill posted about 4 years ago | from the getting-your-head-on-straight dept.

Handhelds 139

ptresadern writes "Researchers at the University of Manchester this week revealed a detailed face tracker that runs in real-time on the Nokia N900 mobile phone. Unlike existing mobile face trackers (video) that give an approximate position and scale of the face, Manchester's embedded Active Appearance Model accurately tracks a number of landmarks on and around the face such as the eyes, nose, mouth and jawline. The extra level of detail that this provides potentially indicates who the user is, where they are looking and how they are feeling. The face tracker was developed as part of a face- and voice-verification system for controlling access to mobile internet applications such as e-mail, social networking and on-line banking."

Finally, something to do with this phone (4, Interesting)

Anonymous Coward | about 4 years ago | (#33328712)

I love my N900, it's a shame Nokia doesn't. Still waiting for MeeGo, and to get the best out of my device I've OC'ed it slightly, not to mention transition and touch screen sensitivity tweaks which all make the phone much more usable. What I want to know is why can't they get it right the first time? Since they didn't, how hard would it be to adopt similar tweaks directly into the OS so it doesn't feel so sluggish? It had/has so much potential, but I'm afraid for now, we'll never see it. As soon as Apple releases an iPhone with a slide out QWERTY keyboard, I'm in.

Why would you bother? That's a completely different class of gear.

iPhone is a phone with a bunch of toys, N900 is a full sub-notebook with phone capabilities tacked on.
The former can run just a few random "apps", the latter allows you to install a regular OS with all of its functionality.

The keyboard is one of significant advantages of N900, but definitely not the main one.
For one, the research done in this article would be flat out impossible on iPhone due to its closed nature.

Re:Finally, something to do with this phone (1, Insightful)

Darkness404 (1287218) | about 4 years ago | (#33328828)

They are two different classes, yes, but the iPhone has a lot of developer focus, the N900 has a few hobbyist developers. Of course you "can" do more for the N900... but only if you want to code it yourself.

In all honesty, just get a Droid, root it and be done with it. Better hardware and better support than the N900.

The N900 was a great idea with a terrible implementation, no ability to buy it subsidized in the US at launch from any major carrier, low amount of apps, etc.

Nokia should have just made the N900 with Android and made it be pre-rooted, it would be a lot more useful.

You can install Debian packages on an N900. It's essentially a tiny ARM tablet running Linux.

If I want something like an N900, but I don't plan to use it on a cell phone carrier, is the N810 any good?

Re:N900 without phone? (2, Informative)

xnpu (963139) | about 4 years ago | (#33329348)

The N810 is bulkier and a bit behind in software version. There's no obligation to use the N900 with a carrier. I don't. I use it with WiFi exclusively.

Re:N900 without phone? (1)

maeka (518272) | about 4 years ago | (#33329450)

re N810:
You can chroot Debian, but not run it natively. Too many drivers are locked down, so you're pretty much forced to use the shipping OS if you expect all your hardware to work.

If you want the unrestricted Linux freedom you're come to expect from a PC on a device of that form factor the N900 is 80% there, the N810 is 50% there.

If I want something like an N900, but I don't plan to use it on a cell phone carrier, is the N810 any good?

IMHO, you should still be much better off with an N900. The N810 is already quite old and have a lot of annoying limitations. It got only 128MB of RAM, which is a major limitation. You can easily get out of memory with the N810 if you browse a heavy web site, and multi-tasking is limited as well. In addition, it got a relatively slow CPU, no OS support for GPU accelaration, 2GB internal storage and a limited size of system space for installing apps.
The N900 got 256MB RAM and 1GB virtual memory (with swap space), faster CPU, 32GB internal storage and up to 2GB for applications.

The N810 have a larger screen, which can be an advantage in some cases, but it is also bigger and heavier.

Better go with an N900. You can find used/refurb units for quite cheap prices on ebay.

"There is an app for that!"
There is an app called "Cellular Modem Control Buttons" which turns off the cell phone circuits.
Once off you can have the N900 connected to Wifi and use Skype, Browse the web (including YouTube) ... use it as you please :)

beermad (961336) | about 4 years ago | (#33330282)

The N900 works fine without needing to use the 'phone capabilities. I have no intention (or need) of using it for telephony, I just use it as a pocket computer and it does a good job. The N810 might be a good option; it'll be cheaper, but it's a lot less powerful and the OS is a lot older, so not everything you might want will build for it (for example, I've ported MySQL 5 to the N900 OS, but the N8XX series will only run MySQL 4).

Re:N900 without phone? (1)

Weezul (52464) | about 4 years ago | (#33330422)

You'll get a warning message during boot up if your N900 has no SIM card, no other issues arise.

You could prevent this message by putting in some old SIM card. I'd recommend against that however as you'll probably save cpu time and batteries if the GSM stack does not initialize.

An N810's only advantage over an N900 is the larger screen, plus maybe you can find one uber cheap on ebay, but really I'd say either buy an N900 or wait for Nokia's first MeeGo device.

It's amazing how you managed to be spot on, but your signature is showing the sad, sad truth of the N900-fanboyish moderators.

I tried evening things out, by spending 15 mod points in this topic alone (and mainly the responses to this comment thread), but as has been noticed for ages when I was a mod on t.m.o and chanop in #maemo, one is not allowed to criticise the N900 in public.

N900 Fanboy: "I'm not a fanboy, I just love my device"

Oh, and from #maemo

(crashanddie) Slashdot has one article about the N900 doing something, and all the fucking fanbois are out
(crashanddie) The few guys who are trying to tell the truth have been modded to oblivion, either "troll" or "flamebait", and all the "I luvz my little n900, it has xterm" are marked as +5 insightful
(pupnik_) N900 Jeopardy! Answer = "LA LA LA LA LA! Not a problem! Don't want to hear about it!"
(pupnik_) Question = "How did nokia deal with pulseaudio taking 12-20% cpu?"
(pupnik_) that would be a specific criticism, crashanddie
(Jaffa) pupnik_: Or "how did Nokia deal with hildon-desktop regression causing 10-15% CPU?"
(Jaffa) pupnik_: Or "how have Nokia helped developers migrate from Maemo to MeeGo with 'legacy' applications?"
(pupnik_) they need to fund a 'this needs to get fixed' contract-based system imo
(crashanddie) pupnik_: Or how Ari Jaaski was talking about "how nokia was skeptical about Open Source, but Maemo and the community convinced them?"
(Jaffa) pupnik_: Or "how did Nokia make such a fast CPU have a laggy and unresponsive UI; which gets worse with updates?"
(crashanddie) Or how Nokia is so free to share their code that everyone can contribute to the code and make the device better?
(crashanddie) because, you know, throwing code out on gitorious and saying "This is dead fish now, we don't care about it anymore" is really "the spirit of open source"

Fanboy reponse?

(Venemo) crashanddie: actually, it was an experiment, and it was successful

and

(Venemo) crashanddie: fortunately, this situation is improved with MeeGo

Arhahahahahahahaha. At least, it's still as funny.

I don't care whether I can talk to my friends on it. I care whether it has connectivity. The 810 wifi is less than wonderful (it's OK, but no iTouch...) but as soon as I step away from a wifi hotspot, it's an island.

Adding cell connectivity is a big win for me.

Ahem.

I had an iPhone before my N900, and frankly I adore the N900. It's fast, responsive, and it's easy to understand what's going on. If the music's skipping (which happened on both devices), I pull up top, then renice my music player. If I want a nice note-taking program, I just run emacs & org-mode on it. Then I'll 'git push' those notes for my other machines. I use citrix to run an app at work (note: despite what the website says, it doesn't actually require motif). The map program (not the stock one, but one you can download a package for) is utterly fantastic. I even have a subway map for my city.

Really, advanced users of the iPhone really just want a mobile computer, with a phone tacked on. The UI on the N900 is pretty good, and it does what I want with few problems, and many, many wonderful plusses over the iPhone platform.

Also, it has a keyboard, replaceable battery, and flash :-) I can stream full-screen flash videos in a cab.

vinsci (537958) | about 4 years ago | (#33330384)

Probably Mappero. or if you want to edit OpenStreetMap, OSM2GO. These are golden. The Nokia Maps application has one big plus, though: you can store complete maps for the whole world on the N900 device (free downloads from Nokia, in case you managed to miss the commercials) so you don't need Internet access while finding your way. I still prefer Mappero though and simply zoom in to the required detail level and go over the route I intend to take in advance, so that Mappero downloads and caches the maps and I can do without Internet access again. Only if I get truly lost, i.e. when I am outside the cached maps in Mappero, do I switch over to the Nokia Maps application. Now if we could have the wonderful Mappero combined with the pre-downloaded Nokia Maps map database, it would be perfect.

Ah, but Nokia recognises the One True Text Editor, and the N900 runs vi out of the box. (It's the minimal BusyBox implementation, but vim is available as an optional package too.)

Re:Emacs? WTF? (1)

vinsci (537958) | about 4 years ago | (#33330586)

Well, you're in luck. The N900 comes with vi pre-installed. Personally, I prefer Emacs of course. After all, the N900 is much more powerful than the desktop computers that existed in the first 10-15 years of Emacs.

I guess our needs and tastes differ... what a surprise!

Re:Finally, something to do with this phone (1, Informative)

Anonymous Coward | about 4 years ago | (#33331074)

Actually there is fix for PulseAudio which reduces skipping by factor of magnitude. With this my overclocked (1GHz) N900 is able to play 256kbit/s oggs in background while surfing the web without skipping. However, it is not perfect, heavy multitasking still causes skips.

You're an idiot. The iPhone runs a regular OS (OS X) just with a different UI designed for small touch-screen usage and it is locked down so you can only do Apple approved things with it. The N900 runs a regular OS (a Linux variant) with a custom UI designed for small touch-screen usage and it is deliberately left wide open and unrestricted so the user can do whatever they want with the device. The big difference between the devices is the restrictions placed on the users and developers.

And who are you to tell me how to be happy, if I want to treat my N900 like the small computer it is rather than a phone that can run a few cool apps, I damn well will.

250,000 huh?

Most of the iPhone apps fall under the following categories:
-small flash-like games
-videos wrapped in an app api
-sound boards

If you are going to count apps like that, then lets add the following to the n900's list
-*actual* flash games (addictinggames.com, etc all work)
-built in unix tools (top, etc)

I'm fairly certain if you compared these now-equivalent lists, you would probably find the n900 has MANY more apps, and that most of them are probably MUCH better written to boot.

Oh, did I mention you can literally write your own apps in almost ANY language you want without paying $100 for a developers key. You can even distribute your own software repository publicly without paying a fee or asking users to void their warranties.

Course, Nokia is a phone company and that's how they market it.

The N900 is a Linux box, which fits in your pocket, and which can talk to GSM, UMTS, WiFi, Bluetooth, FM transmitter and receiver, infrared transmitter, GPS.. Has an accelerometer, touchscreen, 5MP camera, audio (obviously), and TV out.

Lets put it this way. The N900 is a general purpose mobile computing module with battery backup that can do everything, talk to everything, uses open standards and is easy to use.

You can write bog standard shell/python/java/c/ASM/whatever software for it and distribute them as Debian packages.

Anything you can think of to do with a computer, you can do with the blessing of Nokia and you can do it mobile with full knowledge of location and movement. That is the difference between open and closed.

No offense or anything, but it's a no brainer.

If you filled in the extensive questionnaire Nokia sent N900 owners, you were asked to rate the N900 on a scale from "computer with phone functions" to "phone with computer functions". Nokia understands the issue well. I don't think the N900 is anything at all to do with the iPhone/Android world. It is simply a completely different class of machine, and Nokia's low key approach suggests they regard it as a research vehicle. In exchange for supporting their research, you get a piece of equipment targeted at software developers. Yes, it's slower than an iPhone or recent Android devices. It's heavier. It's clunkier. But it's lighter, smaller and more convenient than anything else which I can use to do the same job.

Different in what way? Both use pretty much the same Cortex A8 processor and share many similar specifications - in that regard both units are just 'sub-notebook' type computers with different operating systems. Your argument would perhaps be better defined as "one has better applications for telephony than the other" - these things could be fixed on the N900 but...

Most of those tacked on phone capabilities are a half-arsed attempt, obviously Nokia has tagged the whole lot with "Wont Fix", though many requests have been made to open source it all so developers can hammer out the rough edges themselves. Reading Maemo and MeeGo forums, there is much talk of Nokia doing just this, so there is hope I guess.

To put the difference in a nutshell, iPhone is an "embedded device", ie. software and hardware are meant to be inseparable. It is a device with fixed features (of course running approved "apps" and limited (no Flash) browsing of web services are very powerful features). N900 is a PC in the sense that it/Nokia/Maemo does not try to limit what you can do with it. Real limits (as opposed to limits enforced by software only) of the hardware are the only limitation.

N900 has one software feature: it can run software. iPhone has only the software features explicitly approved by Apple.

Of course if Apple had it's way, they'd bring Macs to the same class as iPhone, running only approved software. But Macs are thought of as computers, so they can't do that. But wait for a displayless iPad Mini with wireless touchpad-keyboard and an HDMI-out, I'm sure that's on it's way... ;-) Actually, just give me "legal" Python or Ruby with reasonable UI library bindings and a developer community, and give me Flash with usable (Linux-like) performance, and I'd buy one as soon as I'd be able get my hands on one.

I love my N900, it's a shame Nokia doesn't. Still waiting for MeeGo, and to get the best out of my device I've OC'ed it slightly, not to mention transition and touch screen sensitivity tweaks which all make the phone much more usable. What I want to know is why can't they get it right the first time? Since they didn't, how hard would it be to adopt similar tweaks directly into the OS so it doesn't feel so sluggish? It had/has so much potential, but I'm afraid for now, we'll never see it. As soon as Apple releases an iPhone with a slide out QWERTY keyboard, I'm in.

You'll have to wait for N9 (if you haven't check the pics or videos of something that may be N9, google for it!). Hopefully it'll be this year, but I'm not holding my breath, even considering how important it would be to get it to stores before Christmas. There'll be a lot iPads and stuff bought for Christmas, and some of those are permanently lost sales for Nokia, if N9 isn't out and available by then.

About N900, I've got a feeling, that the desperate(?) need to get N9 ready and out ASAP might have something to do with N900 not being given more love by Nokia. Ie. the best people are needed to work on N9.

Minority Report would have been a very good picture, if not a great one, if not for a few needless ommissions and intrusions.

The Arwen sequence was included for no other reason than to give the highly overrated Liv Tyler screen time. There just doesn't seem to be enough of a reason to beef up her role. Yeah, sure, the reason commonly given is that it's supposed to give the female viewers something to watch, but it's not like the gals are bored with everything else that's going on. I'm not saying the romantic angle should go unplayed, just that it should be lavished with such loving detail.

Aragorn's fake death was played for dramatic purposes, as if there wasn't enough drama in the story to go around and if there hasn't been enough fake deaths in the first film.

Both of these sequences/occurrences squandered screen time that could have been used to include the Huorns (basically the reason the Ents were called Treeherders) and Shelob, the giant spider. The Huorns are instrumental in routing the Orcs at Helm's Deep; they are an important element in the story. In the film, the defeat of the Orcs wasn't terribly convincing since there were still hordes of them. There didn't seem enough of a reason for them to just turn and flee. A burst of sunlight wouldn't seem to be enough, especially since these Orcs were the Uruk-hai, specially bred to move about in sunlight. In the book, the Orcs were crushed between Gandalf's contigent and the Huorns, which make a lot more sense and would have made a much better movie. There was plenty of time to establish the Huorns if not for unnecessary dream sequences.

Shelob, the spider, was also ommitted for no clearly good reason. Presumably, Shelob will be featured in the the third movie (won't there be enough to take care of in the third movie?). In the book, Frodo seems to be mortally wounded by her and goes into a sort of coma, yet one more time the fake character death card will have to be played (making Aragorn's fake death seem all the more excessive) but at least with Shelob and Frodo, it's warranted and would have made an astounding finish to the film, as it did the second book of Lord of the Rings. (It probably inspired the less-than-happy ending in The Empire Strikes Back and look how good a film that was). It also would have given Samwise (and thus, the Hobbits, who have thus far been little other than "the little people) his moment to shine, as he takes on and defeats Shelob. I disagree there wasn't enough time. For one, as I said before, I don't think the time was spent wisely in telling the story; for another, an extra half an hour to 45 minutes would have been sufficient. Judging from audience reaction to the film, very few would have minded an extended film. Oh well, it will have to wait till the third film. But imagine the anticipation for Return of the King that would have been created if Shelob was included in Towers. Instead, it will just be something that happens in the third film that's quickly resolved (it will have to, I imagine, if the rest of the story is to be told with any sort of efficiency).

Also, the whole Faramir plot was a total, total, hack job that I don't even have the heart to comment on right now. Overall, a severe disappointment. The major bright spot was the performance of Andy Serkis/Gollum, truly an astonishing development in the world of CGI; he makes the severe disappointments of this film almost bearable.

Re:OpenCV (1, Insightful)

Anonymous Coward | about 4 years ago | (#33328816)

Should be easy enough to add detection to reduce the chances of this occurring. By asking the person to turn their head slowly, you can make sure that the various features move according to a 3-d object rotating as opposed to a flat object rotating. Another paper that I just found suggests checking for blinking. This wouldn't solve holding up the phone to a video display showing a person turning their head or blinking, of course, but it would make it marginally more difficult to spoof. And you should always back up biometric authentication with some other form of authentication, such as a password or RFID or something.

On a side note, this entire field is packed with patent landmines, especially from Japanese companies, so be careful before writing an "app for that" and trying to sell it.

Re:OpenCV (2, Informative)

queazocotal (915608) | about 4 years ago | (#33328902)

Not quite.
For example - face recognition plus "now smile" "now frown" - required the attacker to be using some sort of video system.

Face recognition plus a short list of words that the user has assigned an emotion - for example - the phone
displays in sequence the words
Fish (erman drowned) = frown
Localsportsteam (won) = smile ...

Or gaze tracking on a virtual keyboard.

It's the old convenience vs. security argument. Personally for things like my money, I'm willing to go the extra mile and enter a password (or some kind of one time code if only my bank offered it).

dbcad7 (771464) | about 4 years ago | (#33329430)

Yes a lot of people do some very stupid things, like use the same password for multiple accounts. Using the same username and password for your email, bank, and every other place you visit may be easy.. but it's also easy for the bad guys too.. Banking in particular is one account that should not have a username or password used on any other accounts..

Re:Gut reaction.. (0)

On a large number of sites the attacker can simply click the "I forgot my password" link and receive a new password (or a single-use link to change the password) in e-mail.

But.. A password, then face verification? Facebook et al. I'd be happy with face only, ditto with emails, but for the banking stuff it'd be great to have both. As you enter the password, the face recognition does it's business. I'd even love this on the unlocking screen (when the phone goes into keylock due to idleness). My N900 is great, but when someone says "what can it do that my phone can't?", I'm usually at a loss to demonstrate. I know its capable of lots of cool stuff, but currently its shining glory is the FM transmitter, and that's not blow-your-socks-of wow.

I log into my laptop with ssh, then remotely run cheese (remote-X) and check out my webcam from another floor. A really fun trick is to install mpd on the laptop, then watch the webcam until someone starts trying to mess with it and start playing a self-destruct audio file using mpc (or ncmpcpp, etc). My favorite is a star-trek recording with the start of a countdown :D

Re:Gut reaction.. (0)

Isn't mpd + mpc a bit overkill for palying a single sound file. If you just used mplayer from your ssh login it'd still come out of the laptop's speakers and work just as well for the effect you want.

Viola-Jones? (2, Interesting)

airfoobar (1853132) | about 4 years ago | (#33329028)

Can't find any detailed info, but from looking at their demo, I'll guess they are probably using the Viola-Jones method, possibly with a "tree" cascade to detect face angles. The last time I checked, libopencv provided most of the tools to build such as a system, as well as pre-trained detectors for individual face features. Not much invention going on here, but possibly some innovation -- I'd be interested to see more info, if anyone knows where to find it.

Re:Viola-Jones? (1)

hannson (1369413) | about 4 years ago | (#33329382)

They're using active appearance models [manchester.ac.uk] that (AFAICT) work quite differently from the Viola-Jones method.

There's also an open source C++ implementation. [imm.dtu.dk]

Ah, cheers. You are right, this is a very different approach than VJ. When I posted that comment I was actually looking at the YouTube video linked in the /. article that is definitely using VJ -- why is there a completely unrelated video linked in the article?!?

Anyway, I remember I did some work with Active Shape Models many many years ago, though we were trying to fit a 3d face model on the image instead of a 2d template -- much harder (and painfully slow with the computers we had in those days).

Photos (1)

gilesjuk (604902) | about 4 years ago | (#33330614)

Can it be fooled with a photo though? this is the whole problem with using face recognition alone for security.

It really needs to do more than just look at the front of your face.

Two cameras would be better, 3D image. Although even that could be fooled with a 3D model of someone's face. If gaining access to a famous person's bank account you could steal a waxwork dummy head and use that, okay a bit far fetched but if the stakes were high?

Let's not forget the scene in Demolition Man where Simon Phoenix needs a retina scan to get out of the jail, so he uses an eye of a prison guard stuck on the end of a pencil.

Biometrics should be used in conjunction with existing methods, they are not a replacement for passwords or PIN codes.

Some weird anomalies in that video... (1)

knarf (34928) | about 4 years ago | (#33330700)

If you look close at the video during the '360 rotation' segment you'll see the tracking dot for the guy's chin on top of the video camera lens and after that on top of his finger. Does it actually track that part of the face or does it merely deduce the presence of a chin in that region from the position of the eyes?
