As an update to my earlier post, David Cohen, LA Lisper, let me know that slashdot posted about Evolution's partnership with Wowwee.
The thread is terrible, except for a followup from the original poster, a Caltech grad student with an interest in computer vision, in which he gives a nice short description of the actual technology that WowWee will be using.
The first bit of technology Evolution Robotics will probably be contributing is their ViPR [evolution.com] (Visual Pattern Recognition) tech, which allows for real-time recognition of objects in the environment. It's really quite impressive to see it in action -- it can learn how an object looks using just a single training example, has a high recognition rate, is resilient to occlusion/rotation/scale, and can operate at 15fps on an ordinary computer. It works by efficiently extracting a few hundred SIFT [wikipedia.org] (scale-invariant feature transform) features from an image, and then learns what affine arrangement of them indicate an object. A downloadable demo is available on the ViPR page.
(Apparently the slashdot editors cut all that interesting stuff from the original submission because it didn't have anything to do with beer. Way to stay interesting, guys.)Posted by jjwiseman at April 05, 2006 10:22 AM
