  1. I don’t have a kinect to test here, but it looks like you are trying to find contours on the color image – not on the depth image. Is that what you meant to do? Are you working from an example sketch? What kind of contour are you trying to find – the silhouette of a person?

  2. I believe that the two cameras (the color camera and depth camera) are different sizes. Many kinect tutorials suggest ways of dealing with this issue.

Have you tried the MaskTest example from the library you are using?
