Before we start to detect a face in front of the Kinect camera, we should set up the include and library files of the face tracking library. For Visual Studio users, first add ${FTSDK_DIR}/inc
to the current include directories of your project, and add ${FTSDK_DIR}/Lib/x86/FaceTrackLib.lib
to the additional dependencies. You may also have to manually copy all the files in ${FTSDK_DIR}/Redist/x86
to your executable folder to help find these dynamic library files smoothly.
Now we will work on a Kinect example we have done before, which has already initialized the Kinect context for the new face tracking library that is ready to use.
