Color detection in AS3 possible?

Question

Hey, i was wondering what do the AS3 experts would do to detect a color with the webcam (red) and draw a sprite on those color boundaries.

Thanks in advance.

Answer 1

You can access the pixel data in BitMap (Or more correctly, the associated BitMapData) to write your own filter, or you could use a BitmapFilter.

You should be able to capture a bitmap from the webcam by drawing Video to a bitmap you create (use draw() to draw the current video image).

So this should get you a bitmap and a way of detecting pixels in it. Now you can change the bitmap to add your own graphics (or put them in a sprite that is on top of the bitmap). Show the bitmap on screen after you've changed it, and repeat this for every frame :-)
