Made with Max5. Using jit.freenect and cv.jit objects... and some GLSL, Java, and JavaScript...

TRACKING UPDATES: (for when tracking is enabled)

Now there's a "frame buffer" parameter that defines how long a blob's location/label will be remembered by the tracker after it has disappeared from the frame.

- Default is 0, meaning no frames of memory (when a blob disappears, it's forgotten). This is the original behavior from previous version.
- Value of -1 sets memory to be infinite. When a blob disappears, it's coord/label remains indefinitely. When a new blob appears within that specified distance threshold, the tracker interprets it as that old blob and assigns the old label.
- A value of 30-300 (1-10 sec., assuming 30fps) will remember a blob's coord/label for a short amount of time. This may be good if, for example, a person turns sideways and is momentarily too small to register as a blob.


When autoplay is enabled, a suggested video will automatically play next.
