converting luma levels

So I am tracking in with a Kinect with a Kinect Top and want to make my body a white blur with no background, have room to walk back maybe 3-10 feet back with the kinect tracking anything else or loose the body. This possible? Any suggestions?

Can you rephrase your question? It is not clear to me what you mean.

You should be able to use your player index in the kinect TOP, then use a threshold TOP to end up with some alpha, blur and feedback to get the rest of the way there?

Hope that gives you a nudge.

Yes . Thank you . Player index and a little threshold tweaks does the job nice!
