A major assumption in modern computer vision is that you have to track points on surfaces in order to see in 3D. You can use 2 images from 2 static cameras (“stereo”), or 2 images from 1 moving camera (“motion”).

What components do you need to get Augmented Reality (AR) technology running on your mobile phone?

No more fiddling with weirdly shaped controllers. Just step in front of your television and you can control games with your own gestures (and your… Continue reading Revolution in motion
This photograph was taken about a year ago and shows 15-year-old Blake Robbins asleep in his bedroom. The picture in itself is not that interesting. What is remarkable is that it was taken with the built-in iSight camera of his Apple MacBook laptop, remotely operated by technicians at Harriton High School in Rosemont, Pennsylvania in… Continue reading School’s looking at you, kid
