The final app will consist of the following modules and scripts:
gestures: A module that consists of an algorithm for recognizing hand gestures. We separate this algorithm from the rest of the application so that it can be used as a standalone module without the need for a GUI.gestures.HandGestureRecognition: A class that implements the entire process flow of hand-gesture recognition. It accepts a single-channel depth image (acquired from the Kinect depth sensor) and returns an annotated RGB color image with an estimated number of extended fingers.gui: A module that provides a wxPython GUI application to access the capture device and display the video feed. This is the same module that we used in the last chapter. In order to have it access the Kinect depth sensor instead of a generic camera, we will have to extend some of the base class functionality.gui.BaseLayout: A generic layout from which more complicated layouts can be built.
