Summary

Several image processing approaches can yield improved results when using the Kinect's depth image. In some cases, using the depth image will provide completely different results from the standard image, which can be useful for tracking different interactions. This chapter presented just a few examples of image processing techniques that can be helpful with your Kinect hacks.

Libraries can also be useful in successfully executing many of these types of image processing techniques. However, it is always good to be able to understand how to do pixel-level image processing yourself. This will not only help you understand how the libraries work, but allow you to write your own versions of image processing that are specifically tailored to the interaction you are attempting to create.
