Just a quick note to let everyone know that I posted the source code requested for the webcam motion tracking that I did.

It is in this post: http://visualadvance.com/blog/?p=127

I decided my next step with the webcam was to attempt some motion tracking. After a couple nights work I managed to get something working fairly well.

The short explanation: I created a grid of squares over the webcam input, and each square is checking to see if there is a bright light under it. If it sees a bright light then it tells a green square to move to that position.

Update 12.17.08:
Here is the source code folks:

This is the code for exactly what you are seeing in the video. I won’t be providing a whole lot of support for this version since I have moved past it now in the interest of improving it, and am focusing my energies on those versions (which I may be releasing at a future date).

I am going to keep on posting my explorations with BitmapData until someone stops me.

My latest iteration turns the input from a webcam (or video) into a haltone effect (an idea given to me by Brandon Breaux). The squares analyze the intesity of the color they are over. If they are over a dark color they will get smaller, and if they are over a light color they will get bigger. This naturally causes a halftone effect.

As I promised I integrated the webcam into my last BitmapData test. I also decided to add some repulsion to the mouse so that you can push the squares around, and they will eventually return back to their origin.

BitmapImage_v09

Furthering my explorations with the BitmapData and classes, I came up with this effect. It’s surprisingly easy to change one or two variables and have it give off an entirely different effect. I think my next step will be integrating this with your webcam.
