Architecture

To use this module, first make sure that you have the ALVideoInput module loaded on your robot's NAOqi. Refer to the Vision system section for more details on modules and how the vision system is architectured.

In the Vision system page, we explain that the Video Input Module (VIM) manages the video source and provides every client module (GVM) an access to the video stream. The face detection module is a GVM. When it is started it will register itself to the VIM. All this is handled in the ALFaceDetection module and you don't need to take care of this "registration to the VIM" step.
