I'm trying to use Kinect depth map to mask the RGB image (with jit.freenect.grab). But because of the disalignment of the sensors, I can't get good result. Does anybody have a method to correct this disalignment in Max world ?

kinect-rgb-depth-alignment

You 'd be better off using kinect software based on the OpenNI libraries (eg. jit.openni). It has alignment built in.

I'm going to try this way. Many Thanks dtr.
