Image Recognition on Mobile Phones
mysticalgremlin writes "In a recent presentation, Semacode founder Simon Woodside presents his company's bar code scanning technology that is used in mobile phones. Simon also discusses many places where bar code scanning powered phones are being used. Not bad for an 'image recognizer for a 100 MHz mobile phone processor with 1 MB heap, 320x240 image, on a poorly-optimized Java stack'"
Beleive it or not this is pretty impressive. Computer vision gets quite difficult when you don't have a lot of pixels to work with, as the shapes are all "helpfully" smeared together by the imager. And with the cheap lenses in camera phones, edges can be smeared by more than one pixel. In some of my prior work doing vision systems for Sony Aibos for RoboCup, we had to deal with similar problems (find an orange ball in an image that may be only 3x2 pixels, while ignoring the boundaries between red and yellow objects). So, kudos for the technical achievement, and hopefully they find a better application than the cuecat :)
