“Microsoft Research has recently published a scientific paper and a video showing how the Kinect body tracking algorithm works – it’s almost as amazing as some of the uses the Kinect has been put to!
There are a number of different components that make Kinect a breakthrough. Its hardware is well designed and does the job at an affordable price.
However once you have stopped being amazed by the fast depth measuring hardware your attention then has to fall on the way that it does body tracking.
In this case the hero is a fairly classical pattern recognition technique but implemented with style.”
