this one i think is really interesting.
it reminds me of Ive claing's work and Kandinski's Idea of color and motion and inspirational real time merge and come as an interactive installation awa an interactive performance.

Motion detection and Blob detection

I wanted to do blob detection and motion detection in flash, and make kind of a touch table and a reactable object.

Still, I am experimenting, but I think I found a very good way, and pretty satisfied.
I will use 2 cameras. 1 camera will be infrared light camera underneath the table, to detect the object. I will put some aluminum foil or reflectable markers underneath the object, so that the camera will only see the object, and not the hand. The second camera will be just ordinary camera, detecting dark shadows of human. I hope the rear projection will be able to be a strong light source for people to cast shadow, enabling the camera to see.

For the first IR camera, I will use an external blob detecting program called "tbeta" and use DI technique to detect blobs of the object. Because tbeta is suitable for small blobs, and also, in my unstablized interface, tbeta would not detect the fingers as well as expected.

For the second camera, I will use flash for capturing and detecting the motion of human, because movement of the visitor is more meaningful information as a reaction, rather than a stand still shadow. (honestly speaking, it's simply because the code and the effects are easier to use :P)

I hope i will be able to utilize it well. I should now figure out how to match the stage, and how to draw beautiful image out of the blobs.
