OpenCV FAST corners and OpenGL on iPhone 3Gs

This video demonstrates detection of FAST corners on an iPhone 3Gs on iOS4 using only the official (and Appstore accepted) SDK.
The corners are drawn on a transparent OpenGL-ES (EAGL) layer in orthographic view mode. As you can see it is quite stable.
Total processing time per frame is 10ms. Thousands of corners can be detected and displayed every cycle.

I'll be posting a cool video showing Augmented Reality based on this technique soon!

The difference between this video and my previous videos is that
1. It's extremely fast (10ms total processing time per frame)
2. It does not use any unofficial APIs.
3. It's on an iPhone 3Gs with iOS 4.0.1 (jailbreak not required).

We've also done this in our Success Labs. Source code available:

Hey, this is very cool. We are currently trying to develop something similar, though for a known object which we need to track in 3D space. Are you able to give any pointers? please email james@labibo.com if you can offer any suggestions :) cheers

Wow, very nice job. Any chance of seeing the source code behind this?
