Real-Time, Detailed Face Tracking On a Nokia N900

Posted by Soulskill on from the getting-your-head-on-straight dept.

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."

    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.

    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.

    Yeah, 250 000 apps sounds kind of pathetic to me...
