Re: [Flashcoders] Webcam color tracking
Hey guyz, Thank you all for the replies. I've sorta hacked it... Before I do the getColorBoundsRect, I now do a threshold on the image to make the colors that are close to what my LED looks like, 100% red. I then do the getColorBoundsRect on the red and that works just fine. Now I'll try different colors of LEDs to see which works best and to make sure there's nothing else in the camera's eye that has the same color. It would indeed be great to see how Grant did his Mister Glove... But I'm guessing it's somewhere along the line of what I'm doing here...

As long as you've only got one light, that approach should work. Alias On 12/09/06, Serge Jespers <[EMAIL PROTECTED]> wrote: Well... I need to be able to track a LED light.

Re: [Flashcoders] Webcam color tracking
No, I still used getColourBoundsRect. It works OK until you get more than one object of the same colour - then you end up getting big rectangles which span the distance between the two, which is bad. You could *probably* get around this with some kind of quadtree-type algorithm, it's something I've been meaning to look into, and will probably be going back to soon. (As soon as I get five spare minutes...) Also - Grant Skinner claims to have solved the problem, but AFAIK, he's only posted videos, not working examples, so I don't know what approach he used.

Re: [Flashcoders] Webcam color tracking
Serge, Though I can not provide the source code, I have seen Grant Skinner demo an application that tracks LEDs. You can see it here: http://incomplet.gskinner.com/index2.html#mister In particular, at the link above select "MISTER glove video". Grant explained the details. Perhaps others on this list recall details? g On 9/12/06, Serge Jespers <[EMAIL PROTECTED]> wrote: Well... I need to be able to track a LED light.

Re: [Flashcoders] Webcam color tracking
Interesting... So you didn't use getColorBoundsRect? Did you 'walk through' all pixels then? Or how exactly do you search for the color? Serge Yeah, I've done some work with it. The trick is to apply some contrast filters to reduce the colour depth, and be a bit more picky about getting your source colour. You can do the getColourBoundsRect thing, but it's still pretty inaccurate though.
