FAST Corner Detection port

[matchy]

Here a GLB port of Fast Corner Detection with a still demo by me and some C++ cleaning by Kitty.

If you are wondering what it is, here's a quick cool clip with it demonstrating detection on video frames.

uau! that looks very promising!

That's pretty cool!
If you can get it working on the iPhone, you could do games like ARDefender, an augmented reality tower defense game.

Slydog, it's corner detection, not pattern tracking which requires algorithms. So you can use a web-cam on the PC for now to configure the augmentation as it's only a matter of getting the video preview frame (array data) repeatedly.

Anyhow, that is a cool game.  Alternatively, I wonder about this sort of thing also (mini-projectored gyro-iPhone screen).

Ha, nice gyro video!  So simple in concept, but looks very fun!  Be better will an all white round room!


Ya, but with corner detection, you could still detect your environment perhaps, like a sheet of paper, if nothing else distracting was in the scene.  Heck, rip off one corner (45 degree angle?) so you know the orientation.   

Then plot the game onto the virtual paper since you now know where the corners are, or something. 
Can even go 3D if you *assume* its a sheet of paper and figure out the the angles between the corners to determine the perspective.

Or detect billboards and display your email instead of the boring billboard ad!  (Ha, seen that done a few years ago).
