"Depth Camera" is a new and intriguing ter= m for me. Diving in deep in that promising direction. Looks like IntelRealS= ense is a packaged product that allows us to get this done fairly easily wi= th a proven SDK available in a variety of languages.=C2=A0

kinect or similar (better) cameras , can provide you with the thresho= ld depth you want.

if you prefer difference matte,= it depends often too much on lighting, transparency, color.

Or openFrameworks using C++ (compile in Xcode or Visual Studio)


Not sure what kind of camera you will be using but this is where depth= cameras can really shine.

Unity will do that or you could use OpenCV in Processing.

Personally I would use Processing.

This may be a long shot for this group

I need to build a box that pulls a difference matte continuously.=C2= =A0

We'll setup a camera in a rock solid position. Have complete contr= ol of the background. Need to replace it behind talent in near real time fo= r an installation.

C, C++, Python, almost any language will work.

Thanks!
