Sorry about that, Cat. I was in a hurry.
The greatest problem I am having is the lack of contrast in the image. The camera will be above, like the projector. The project is a floor projection of water-like graphics. And it must be interactive. Okay, the visuals part, the interactivity and these problems are all solved, but the tracking part is driving me nuts.
I tried to use visible light filters on the cameras so that the images projected on the floor do not interfere with the image the camera is capturing, as usual. But this makes the image appear with a very low contrast, messing up with the Trautner output (people appear in parts, and some parts of the body are blended in the background, generating multiple blobs of one person in the Contour). This also messes up the Trautner with a 16 x 16 grid mask. Also, tried using the Difference of Textures shader that comes into the Shaders for Newbies tutorial, but it is suffering the same problems as the Trautner with Hold Background set (obviously). Haven’t tried the ColorTracker or CamShiftTracker, because I don’t know in advance which color to track, and also, the floor will be somewhat blue, so people in blue clothes would not be tracked. But I didn’t tested it for real, so…
Is there a way to improve contrast between the floor and the people that walks on it? Repositioning the IR illuminators, or even using some other tracking technique?
