Cellphone App Developed that Could Allow For 'Pocket Supercomputers' 73

Jack Spine writes "A robotics researcher at Accenture has given a demonstration of a 'Pocket Supercomputer' — a phone behaving like a thin client. It can be used to send images and video of objects in real time to a server where they can be identified and linked to relevant information, which can then be sent back to the user. 'The camera on the phone is used to take a video of an object — such as a book ... By offloading the processing from a mobile device onto a server, there are few limits on the size and processing power available to be used for the storage and search of images.' To pinpoint the features necessary to identify an object, the image is run through an algorithm called Scale-Invariant Feature Transform, or SIFT, a technology developed by academic David Lowe. The software extracts feature points from a jpeg and makes a match against images in the database. If a match exists then the software on the server retrieves information and sends it back to the user's phone. A 'three-dimensional' image of an object can also be uploaded onto the phone, to look at the virtual object from different angles. The motion-tracking technology Accenture uses for this is a free library of algorithms called Open Computer Vision."

      Actually, yes. This is not new. There are already many robots out there that use this exact same technology. The only difference is that this guy used a cell phone.

        I agree completely, the title is highly misleading. The cyclical nature of our industry does make me laugh though, its like every few years the balance of power between the network and the device shifts and WOW!!! a whole new way of computing!!! Repeat and rinse. How people fail to recognize its the same thing over and over, boggles my mind. Oddly though, the cell phone has basically been a thin client all along, and its only recently with Palms Treos, Windows smartphone, Apple iPhone's, etc... that things started trended towards thick clients again.

        Lastly, atleast here in Canada, this idea is completely unrealistic anyways as the bottleneck is essentially the network not the device. A combination of high data charges, no flat rate billing plans and slow networks just doesn't mix well.

            It's getting better... you can get a gb/month or so (subject to the usual restrictions, like no voip, msn, etc.) whereas a couple of years ago you were lucky if you got 4mb/month.

            I still remember the £300 bill I got from connecting my laptop to the phone one day and leaving windows update still enabled.. aargh. That was when the excess was something like £5/mb.

            Mobile data will become useful to me when it's at about the rate of DSL.. or even in the same ballpark would be nice.
        • Canada is slowly getting better though. It wasn't that long ago that a $100 data plan with Rogers earned you only 100mb of wireless downloads. Now with the newly unveiled Flexrate data plans (mainly intended for their hsdpa laptop data card users) you can get 5gb of downloads for $100. That's definitely not garnished with an 'unlimited' label, but they're definitely getting closer.

    Wasn't there a segment on NPR about a cellphone with an integrated 'reader' that did OCR on pictures taken with your cell phone? I could definately see OCR as something that you would want to offload to a server, potentially one designed just for that.

      My HTC Tytn II phone has a built-in app called WorldCard Mobile that does something similar. You take a picture of a business card, and the software does OCR on the image & creates a Pocket Outlook contact record with the OCR text. It's not the best OCR I've seen, but it's not the worst, either.

      If a computer is linked to others and performs better than original specs indicate that it should, then maybe it earns the elite term of super.

    While this sounds cool, it interests me more because of the fact that the Open Computer Vision algorithms [intel.com] are open sourced and in this case by Intel's research groups. While I might prefer if another microprocessor company was more dominant, there are some areas where Intel's interests diverge from the unholy Wintel alliance, and in these areas they do some really good stuff.

      I agree that QRCode [wikipedia.org] is nifty, and hope that it and/or similar systems take off around the world, but this is a little different.

      All the QRCode processing is done on-phone. This idea has a tightly-coupled client-server relationship, and is a step in the direction of distributed mobile code and data (overdue and welcome, in my book).

    It's just a thin client on a mobile phone, and not an especially interesting one. They use SIFT, so they don't stand a chance in hell of doing anything useful on the phone. There are other, modern, much more lightweight ways of identifying features. It would be more interesting performing as much processing on the phone as possible (for instance to reduce bandwidth and/or latency).

    Other than that, it's a neat hack.

      It would be more interesting performing as much processing on the phone as possible (for instance to reduce bandwidth and/or latency).

      However, a cell phone has hardly the processing power to be able to perform image classification, let alone against a database of trained patterns. It might be able to extract one or two features from an image, such as RGB concentrations and hue/luminescence, but today's cell phones would have great difficulty extracting text from an image -- something that Accenture's "hack" can't yet do.

          Is corner detection in the same league as far as doing object recognition in a real environment as SIFT?
          • SIFT is part of an object recognition system. Sift finds "interesting" points, and computes useful features from the pixels around those interesting points. An object recognition system would then do something useful with SIFT points, such as matching in to a database.

            SIFT relies on finding interesting points to start with, and the field of finding interesting points is "corner detection". The standard SIFT implementation uses a difference-of-gaussian detector which is pretty slow.
