Multitouch recognition test

My first multitouch test, using technique called diffused illumination. Setup build of plexiglass, tracing paper, and desk lamp for illumination. Software written in C++, using DirectShow for camera input and DirectX for visualization (no video lib). Algorithms are based on Touchlib.

Can you tell me how to filter? (0:40~0:42)

Just say how to do.

Gaussian Smoothing Filter ?

Thanks.

(My English is not well,Because I am Taiwanese,But you can tell me by English.)

Filtered = Original - BoxBlur(Original)

So there are two filters:

-BoxBlur (Linear Smoothing)

-Image subtract

Box Blur kernel size need to be adjusted to the fingers size.

With what language did you write the driver?

[DamianXVI]

C++, but it's not a "driver", just a user-mode application connected to DirectShow.
