CHAPTER 3: Depth Image Processing > Seeing Through the Eyes of the Kinect

Seeing Through the Eyes of the Kinect

Kinect is different from all other input devices, because it provides a third dimension. It does this using an infrared emitter and camera. Unlike other Kinect SDKs such as OpenNI, or libfreenect, the Microsoft SDK does not provide raw access to the IR stream. Instead, the Kinect SDK processes the IR data returned by the infrared camera to produce a depth image. Depth image data comes from a DepthImageFrame, which is produced by the DepthImageStream.

Working with the DepthImageStream is similar to the ColorImageStream. The DepthImageStream and ColorImageStream both share the same parent class ImageStream. We create images from a frame of depth data just as we did with the color stream data. Begin to see the depth stream images by following these steps, which by now should look familiar. They are the same as from the previous chapter where we worked with the color stream.
